Description

Technical Field

[0001] The invention belongs to the technical field of animal health products, and in particular relates to an animal calcium supplement product and a preparation method thereof. Background Art

[0002] Calcium is one of the essential mineral elements in animals. It plays a key role in supporting bone structure, nerve conduction, muscle function and many other biological processes. For animals, especially domestic pets, livestock and wild animals, an adequate supply of calcium is extremely important to maintain their health. With the continuous development and professionalization trend of the pet market, the health and nutritional management of pets have gradually received more and more attention, among which calcium intake and management have become a core topic.

[0003] However, despite the presence of a variety of calcium supplement products on the market, existing calcium supplementation technology still faces some challenges. Currently commonly used calcium supplement products are mainly based on inorganic calcium compounds, such as calcium phosphate and calcium chloride. Although these inorganic calcium sources have a high calcium content, their absorption rate in animals is generally low due to the limitations of their chemical structure. In addition, although organic calcium compounds such as calcium citrate are easier for animals to absorb, their calcium content is relatively low, and due to the presence of large molecular organic groups, the overall effect is still not ideal.

[0004] The main drawbacks of the prior art are the selection of calcium sources and the efficiency of calcium absorption. Although inorganic calcium has a lower cost, its low absorption rate leads to insufficient calcium utilization in animals, which may cause a variety of health problems such as calcium deficiency and osteoporosis. For organic calcium, although its absorption rate is better, its cost is high and its calcium content is insufficient, which cannot meet the growing calcium needs of pets and livestock, especially during the rapid growth stage or breeding period.

[0005] In summary, existing calcium supplementation technologies have significant limitations in animal health management, especially in terms of calcium bioavailability and economic efficiency. These limitations not only affect the overall health of pets and livestock, but also restrict the further development of the related product market. Therefore, finding an efficient and economical calcium supplement method to improve the absorption rate and utilization efficiency of animal calcium is an urgent problem to be solved in the current field of animal health technology.

[0072] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0073] In an embodiment of the present application, an animal calcium supplement product is provided, including: calcium hydrogen phosphate, milk calcium, natural plant products, lactose-free milk powder, animal oil, animal hydrolyzate, fructooligosaccharide, casein phosphopeptide, thickener, microbial fermentation product, L-lysine hydrochloride, collagen, preservative, natural antioxidant and vitamin D3;

[0074] In the above embodiments of the present application, the animals targeted may include but are not limited to pets, domestic animals, wild animals, etc. Among them, pets, such as dogs, cats, etc., may be particularly targeted.

[0075] The animal calcium supplement product may be at least one of food (such as staple food, snacks), health care product and medicine.

[0076] The form or dosage form of animal calcium supplement products may include but are not limited to tablets, granules, powders, pills, oral solutions, injections and microneedles, etc. In addition, it may also be other forms suitable for administration to animals and conducive to calcium absorption, which will not be repeated here.

[0077] Animal calcium supplements include a variety of different ingredients, each of which has its own specific functions and effects, as follows:

[0078] (1) Calcium hydrogen phosphate: This is an inorganic calcium source that contains a higher proportion of calcium. Calcium hydrogen phosphate is added to provide a stable calcium content. Although its absorption rate is not as high as that of organic calcium, its cost is lower, which can reduce the overall cost of the product while ensuring efficient and safe calcium supplementation.

[0079] (2) Milk calcium: An organic calcium source extracted from milk that is more easily absorbed by the body than inorganic calcium. Milk calcium not only provides calcium, but also contains other minerals and trace elements that help calcium absorption. This calcium source can improve the overall absorption efficiency of calcium supplement products.

[0080] (3) Natural plant products: These may include plant extracts rich in trace minerals and vitamins, which help improve the overall nutritional status of the animal and thus indirectly promote calcium absorption and utilization.

[0081] (4) Lactose-free milk powder: Provides protein and other nutrients to lactose-intolerant animals without causing discomfort. This makes calcium supplement products suitable for a wider range of animal groups. For example, cats are lactose-intolerant animals. Most adult cats lack sufficient lactase, an enzyme required to digest lactose (the sugar in milk). Therefore, when cats ingest milk or dairy products containing lactose, they may not be able to fully digest these sugars, leading to indigestion, diarrhea, or gastrointestinal discomfort. For calcium supplementation, it is important to choose a lactose-free formula for cats or other lactose-intolerant animals to avoid causing unnecessary gastrointestinal problems.

[0082] (5) Animal oil: mainly provides energy and essential fatty acids, helps dissolve and transport fat-soluble vitamins such as vitamin D, which is essential for calcium absorption.

[0083] (6) Animal hydrolysates: These are small molecule proteins and amino acids obtained by hydrolyzing animal proteins. They are easy to absorb, can improve nutritional efficiency, and support intestinal health.

[0084] (7) Fructooligosaccharide: A natural prebiotic that helps promote the growth of a healthy intestinal microbiome, which is important for nutrient absorption and overall health.

[0085] (8) Casein phosphopeptide: It is a bioactive peptide that can improve calcium absorption and help enhance the bioavailability of calcium, especially in the absorption of organic calcium.

[0086] (9) Thickeners: used to improve the taste and stability of the product, making it easier to mix and store while ensuring even distribution of nutrients.

[0087] (10) Microbial fermentation products: These products may contain probiotics, which help maintain intestinal health and improve the absorption of nutrients, especially minerals and vitamins.

[0088] (11) L-Lysine hydrochloride: Lysine is an essential amino acid that helps optimize the absorption and utilization of calcium by binding with calcium to form a more absorbable complex.

[0089] (12) Collagen: It is beneficial for supporting the joint health and overall bone strength of animals, especially while supplementing calcium, helping to improve the health of bones and soft tissues.

[0090] (13) Preservatives: Ensure the stability and safety of the product during the shelf life and prevent microbial contamination.

[0091] (14) Natural antioxidants: Help prevent product oxidation, maintain the effectiveness and safety of active ingredients, and reduce reliance on chemical preservatives.

[0092] (15) Vitamin D3: A vital vitamin that promotes the absorption and metabolism of calcium and phosphorus, enhances the bioavailability of calcium, and is an indispensable component of calcium absorption.

[0093] If you do not supplement vitamin D3 while supplementing calcium, it is very easy to reduce the absorption efficiency of calcium, thus affecting the utilization and retention of calcium. Specifically, it includes the following: reduced absorption rate, vitamin D3 is a key factor in promoting calcium absorption. Without sufficient vitamin D3, the intestinal absorption capacity of calcium will be significantly reduced, resulting in the ineffective utilization of supplemented calcium; increased calcium excretion, because vitamin D3 helps regulate the kidney's reabsorption of calcium, vitamin D3 deficiency may lead to reduced renal reabsorption of calcium, thereby increasing calcium excretion in urine; blood calcium level fluctuations, vitamin D3 helps maintain the stability of blood calcium levels. Vitamin D3 deficiency may cause fluctuations in blood calcium levels and affect calcium balance; impaired bone health, due to reduced calcium absorption and utilization efficiency, long-term vitamin D3 deficiency may lead to bone health problems, such as osteoporosis and increased risk of fractures; metabolic disorders, vitamin D3 is also involved in regulating calcium and phosphorus metabolism in the body, vitamin D3 deficiency may lead to calcium and phosphorus metabolism disorders, affecting the normal development and maintenance of bones; affecting other nutrients, vitamin D3 also affects the absorption of other nutrients, such as phosphorus. The absorption and utilization of calcium and phosphorus are interdependent. A lack of vitamin D3 may affect the absorption of phosphorus; immune function: Vitamin D3 has a positive effect on the immune system. A lack of vitamin D3 may affect the pet's immune function and increase the risk of infection; overall health: long-term lack of vitamin D3 not only affects bone health, but may also have a negative impact on the pet's overall health, including muscle function, nervous system health, etc.

[0094] Therefore, in the embodiments of the present application, in order to ensure the effectiveness and safety of animal calcium supplement products, vitamin D3 is added to increase the absorption rate of calcium, maintain calcium balance, and support bone health.

[0095] These ingredients work together to not only provide an efficient calcium supplement solution, but also support the overall health of the animal, increase the product's overall calcium supplement performance and efficiency, as well as its competitiveness and attractiveness in the market.

[0096] In short, this animal calcium supplement product provides a comprehensive solution through the compatibility and combination of different components to support the animal's bone health, improve nutrient absorption efficiency, and comprehensively enhance the animal's overall health.

[0097] Further, the natural plant product includes at least one of sucrose, yucca powder and marigold powder;

[0098] Sucrose is usually used as a sweetener to improve the taste of products.

[0099] Yucca powder contains a variety of beneficial compounds and has certain anti-inflammatory and antioxidant effects.

[0100] Marigold powder, rich in lutein and zeaxanthin, which are beneficial for eye health, also helps to increase the antioxidant properties of the product.

[0101] Further, the lactose-free milk powder includes at least one of lactose-free goat milk powder and lactose-free cow milk powder;

[0102] Above, lactose-free goat milk powder and lactose-free cow milk powder: provide high-quality protein and other nutrients to avoid digestive problems in lactose-intolerant animals such as cats.

[0103] Further, the animal hydrolyzate includes at least one of beef hydrolyzate paste, chicken hydrolyzate powder and chicken hydrolyzate paste;

[0104] Above, Beef Hydrolyzed Paste, Chicken Hydrolyzed Powder and Chicken Hydrolyzed Paste: provide easily digestible protein and amino acids to help enhance nutrient absorption and utilization.

[0105] Furthermore, the microbial fermentation product includes at least one of yeast hydrolysate, fermented soybean meal and fermented apple pomace;

[0106] As mentioned above, yeast hydrolysate, fermented soybean meal and fermented apple pomace can be used to provide prebiotics and enzymes, promote intestinal health, and enhance the absorption of calcium and other nutrients by animals.

[0107] Further, the preservative includes at least one of potassium sorbate, sodium benzoate, and citric acid;

[0108] Above, Potassium Sorbate, Sodium Benzoate, Citric Acid: Help prevent product spoilage, extend shelf life, and maintain product freshness and safety.

[0109] Further, the natural antioxidant includes at least one of natural vitamin E, rosemary extract, and L-ascorbic acid;

[0110] Above, Natural Vitamin E, Rosemary Extract, L-Ascorbic Acid (Vitamin C): Protect sensitive ingredients in the product from oxidative damage, prolong product stability while providing additional health benefits.

[0111] Further, the animal oil includes at least one of chicken oil, fish oil, beef tallow and duck oil;

[0112] As mentioned above, chicken oil, fish oil, butter and duck fat are used to provide essential fatty acids, help promote the absorption of fat-soluble vitamins (such as vitamin D), and are beneficial to heart health and immune function.

[0113] Furthermore, the thickener includes at least one of pectin, gellan gum and sodium carboxymethyl cellulose.

[0114] As mentioned above, pectin, gellan gum and sodium carboxymethylcellulose are used to improve the texture and stability of the product, ensure the uniform distribution of ingredients, and enhance the overall sensory quality of the product.

[0115] The combined effect of these ingredients enables calcium supplement products to not only effectively provide calcium, but also optimize the overall nutritional status and digestion and absorption efficiency of animals, while ensuring the acceptability of the product and safety for long-term use.

[0116] It should be noted that lactose-free milk powder (such as lactose-free cow's milk powder and goat's milk powder) provides protein and other nutrients, while animal oil (such as fish oil) is rich in Omega-3 fatty acids, which can help improve the absorption of fat-soluble vitamins. Therefore, lactose-free milk powder and animal oil have a certain synergistic effect in the components.

[0117] Animal hydrolysates (such as beef hydrolyzate) provide easily absorbed amino acids, and thickeners (such as sodium carboxymethyl cellulose) can help stabilize the distribution of these proteins in the product, ensuring uniform release and absorption of nutrients.

[0118] It should be noted that natural antioxidants and vitamin D3. Natural antioxidants (such as natural vitamin E and rosemary extract) can help protect vitamin D3 and other sensitive ingredients from oxidative damage. Vitamin D3 is an indispensable factor for calcium absorption. The protective effect of antioxidants can ensure the effectiveness of vitamin D3.

[0119] Furthermore, the animal calcium supplement product comprises the following components in parts by weight:

[0120] 2 to 20 parts of calcium hydrogen phosphate; 2 to 20 parts of milk calcium; 1 to 10 parts of natural plant products; 1 to 10 parts of lactose-free milk powder; 1 to 10 parts of animal oil; 1 to 10 parts of animal hydrolyzate; 1 to 10 parts of fructooligosaccharides; 0.5 to 5 parts of casein phosphopeptide; 0.5 to 5 parts of thickener; 0.5 to 5 parts of microbial fermentation products; 0.5 to 5 parts of L-lysine hydrochloride; 0.05 to 0.5 parts of collagen; 0.05 to 0.5 parts of preservatives; 0.05 to 0.5 parts of natural antioxidants; 0.005 to 0.1 parts of vitamin D3.

[0121] For further reference, Figure 1 and Figure 2 The animal calcium supplement product is in the form of composite sandwich particles; wherein, Figure 1 It is the appearance structure of composite sandwich particles. Figure 2 It is a schematic diagram of a local cross section.

[0122] The composite sandwich particles include calcium hydrogen phosphate, milk calcium, natural plant products, lactose-free milk powder, animal oil, animal hydrolyzate, fructooligosaccharide, casein phosphopeptide, thickener, microbial fermentation products, L-lysine hydrochloride, collagen, preservatives, natural antioxidants and vitamin D3 as calcium supplement cores, and also include a gastric acid secretion-promoting shell coated on the outer surface of the calcium supplement core;

[0123] The particles of the calcium supplement product are the composite sandwich particles consisting of the calcium supplement core and a gastric acid secretion promoting shell coated on the outer surface of the calcium supplement core.

[0124] It should be noted that the animal calcium supplement product provided by the present invention contains organic calcium and inorganic calcium. Among them, milk calcium, as an organic calcium source, has high bioavailability, that is, it has high efficiency of absorption and utilization in the body. Milk calcium contains not only calcium, but also other minerals and trace elements that help calcium absorption, such as magnesium, phosphorus and vitamin D, but the relative calcium content of milk calcium is low; calcium hydrogen phosphate is an inorganic calcium source, which is characterized by a relatively high calcium content and relatively low cost. Although its bioavailability is not as good as organic calcium, it provides an economical and effective way to increase the total calcium content in the product.

[0125] The use of dicalcium phosphate can increase the total calcium content in the product without significantly increasing the cost of the product. This is an important consideration for commercial calcium supplement products that need to be mass-produced and widely distributed. The addition of milk calcium at the same time ensures the bioavailability of calcium, allowing animals to better absorb and utilize the supplemented calcium, thereby improving the overall effect of calcium supplementation. In addition, different animal species and different health conditions may require different forms of calcium. By providing two forms of calcium, the product can be more widely adapted to the nutritional needs and health conditions of different animals. In addition, it is very important to maintain an appropriate ratio of calcium and phosphorus in animal feed and nutritional supplements. The phosphorus component provided by dicalcium phosphate can help balance the ratio of calcium to phosphorus, which is essential for animal bone health and cell function.

[0126] In summary, by combining milk calcium and calcium phosphate, animal calcium supplement products can more effectively meet the various calcium supplementation needs of animals, while improving the economic and biological effectiveness of calcium supplementation. This formulation strategy is designed to optimize the animal's calcium absorption and utilization, thereby better supporting the animal's overall health.

[0127] It should be noted that when calcium hydrogen phosphate is used as calcium supplement in animals, its absorption pathway is specifically as follows:

[0128] (1) Entering the digestive system: Calcium hydrogen phosphate first enters the digestive system through oral ingestion. It begins to decompose after encountering gastric acid in the stomach, which helps release the calcium and phosphorus ions in it.

[0129] (2) Gastric acid effect: In the stomach, calcium hydrogen phosphate partially dissolves to form ionic calcium (Ca 2 +) and phosphorus (H2PO4 - ), this is because gastric acid is mainly hydrochloric acid HCl, which can provide a sufficiently acidic environment to promote the decomposition of calcium hydrogen phosphate.

[0130] (3) Absorption in the small intestine: After entering the small intestine from the stomach, the absorption of calcium hydrogen phosphate mainly occurs in the upper part of the small intestine, especially in the duodenum and jejunum. The pH of the small intestine is higher than that of the stomach, which helps to further dissociate and absorb calcium and phosphate ions.

[0131] (4) The role of vitamin D: Vitamin D plays a vital role in the absorption of calcium hydrogen phosphate. Vitamin D increases the active transport and channel absorption of calcium ions by promoting the production of calcium binding proteins in small intestinal epithelial cells. Without sufficient vitamin D, the absorption efficiency of calcium will be greatly reduced.

[0132] (5) Transmembrane transport: The absorption of calcium and phosphate involves several mechanisms, including active transport and passive diffusion: Active transport: relies on calcium pumps on the cell membrane (such as Ca 2+ -ATPase) and transport proteins (such as calcium transporters), all of which require regulation by vitamin D; passive diffusion: driven by the concentration gradient of calcium and phosphate in the small intestine, through the intercellular space.

[0133] (6) Blood transport and utilization: Once absorbed, calcium and phosphorus are transported through the blood to tissues and organs that need them, such as bones, where they participate in bone formation and maintenance. Calcium is also involved in nerve signal transmission, muscle contraction, and other important physiological functions.

[0134] (7) Excretion and regulation: The levels of calcium and phosphorus are regulated by the kidneys, and excess calcium and phosphorus can be excreted from the body through urine. In addition, hormone systems (such as parathyroid hormone and calmodulin) are also involved in regulating the balance of calcium and phosphorus in the body.

[0135] From the above absorption pathway of calcium hydrogen phosphate, it can be seen that the absorption of calcium hydrogen phosphate focuses on the role of gastric acid. The hydrochloric acid in the stomach fully reacts with calcium hydrogen phosphate to release calcium ions and phosphate ions. The following is a simplified representation of this reaction:

[0136] Ca(H2PO4)2+2HCl→CaCl2+2H3PO4; (1)

[0137] Among them, calcium hydrogen phosphate (Ca(H PO)) is an acidic salt with two replaceable hydrogen atoms. Hydrochloric acid (HCl) is a strong acid that reacts with calcium hydrogen phosphate to replace the hydrogen ions in it, forming calcium chloride (CaCl) and phosphoric acid (HPO). Calcium chloride is a water-soluble salt that dissolves easily in the stomach. The phosphoric acid produced is a weak acid, but it is also relatively stable in the environment of stomach acid. This reaction helps to convert the calcium ions in calcium hydrogen phosphate into a form that is easier to absorb in the small intestine, thereby improving the bioavailability of calcium.

[0138] When calcium chloride (CaCl) is dissolved in water, it dissociates into calcium ions (Ca 2 +) and chloride ion (Cl-). This process can be represented by the following chemical equation:

[0139] CaCl2→Ca 2+ +2Cl - ; (2)

[0140] In this reaction: Calcium chloride is an ionic compound. When it dissolves in water, its crystal structure is destroyed, and calcium ions and chloride ions are surrounded by water molecules and dispersed into the solution. 2 +) is a positive divalent ion in aqueous solution. It is the active form of calcium and can directly participate in various physiological processes in organisms, such as bone mineralization. Chloride ion (Cl-) is a negative monovalent ion, and its main function is to maintain electrolyte balance and acid-base balance of body fluids.

[0141] Therefore, the dissolution of calcium chloride in water helps to provide calcium ions that can be absorbed and utilized by organisms, which is very important in calcium supplementation and various biological functions.

[0142] As an inorganic calcium source, the absorption process of calcium hydrogen phosphate in animals is highly dependent on the secretion of gastric acid. Gastric acid not only helps calcium hydrogen phosphate dissociate into absorbable calcium ions, but also indirectly promotes calcium absorption by affecting the intestinal environment. Therefore, when the animal is fasting, or when the stomach does not produce sufficient gastric acid under other circumstances, the absorption efficiency of calcium hydrogen phosphate will be reduced, resulting in a significant reduction in calcium absorption efficiency and conversion efficiency, affecting the calcium supplementation of animals.

[0143] In the embodiments of the present application, in response to the situation that the animal is on an empty stomach or other situations that cause the stomach to not produce enough gastric acid, the form of the animal calcium supplement product is set to be a composite sandwich particle, including a calcium supplement core and a gastric acid secretion-promoting functional shell, wherein the calcium supplement core serves as the core material, and the gastric acid secretion-promoting functional shell serves as the coating material, which is coated on the outer surface of the calcium supplement core.

[0144] The core of calcium supplement consists of calcium hydrogen phosphate, milk calcium, natural plant products, lactose-free milk powder, animal oil, animal hydrolyzate, fructooligosaccharide, casein phosphopeptide, thickener, microbial fermentation products, L-lysine hydrochloride, collagen, preservatives, natural antioxidants and vitamin D3, which play the main role of calcium supplement after oral administration.

[0145] The outer coating material, i.e., the gastric acid secretion promoting shell, is used to contact the gastric mucosa when entering the stomach of an animal to promote the production of gastric acid. Its advantages are:

[0146] (1) Improve the absorption rate of inorganic calcium: Since inorganic calcium such as calcium hydrogen phosphate requires gastric acid to dissociate into absorbable calcium ions, the shell with gastric acid secretion promoting function can increase gastric acid secretion, thereby improving the dissociation and absorption rate of inorganic calcium.

[0147] (2) Optimizing the bioavailability of calcium: By promoting gastric acid secretion, the digestive environment of animals can be improved, so that the calcium source in calcium supplement products (whether inorganic calcium or organic calcium) can obtain better bioavailability.

[0148] (3) Adapt to the digestive capacity of different animals: Especially for young animals or animals with insufficient gastric acid secretion, this design can compensate for their insufficient gastric acid secretion and ensure that they can effectively absorb the supplemented calcium.

[0149] (4) Improve product applicability: For animals that are fasting or have not eaten for a long time, the gastric acid secretion-promoting shell can help them quickly produce sufficient gastric acid when they ingest calcium supplements, thereby absorbing calcium in a timely manner.

[0150] (5) Enhanced calcium supplementation effect: By increasing gastric acid secretion, the calcium supplementation effect can be enhanced, so that calcium supplement products can better meet the calcium needs of animals, especially for rapidly growing animals or animals in special physiological states (such as pregnancy and lactation).

[0151] (6) Promote overall digestion: Increased gastric acid not only helps calcium absorption, but also promotes overall digestion, improving the animal's appetite and nutrient absorption.

[0152] (7) Improve product stability: The gastric acid secretion-promoting functional shell may contain some protective ingredients that can protect the stability of the calcium supplement core during storage and transportation and prevent the ingredients from degrading or becoming ineffective.

[0153] (8) Considering that calcium supplement products also contain other nutrients and additives, the gastric acid secretion-promoting functional shell helps the simultaneous absorption and utilization of these ingredients, thereby achieving comprehensive nutritional supplementation.

[0154] The animal calcium supplement product provided in the present application is provided in the form of a composite sandwich particle. This design provides a novel calcium supplement method, and by combining gastric acid secretion promotion and calcium supplementation, provides a new idea for the research and development and application of animal calcium supplement products. The calcium supplement product with this special design is unique in the market, can attract consumers, and improve the market competitiveness of the product.

[0155] In summary, the design of the gastric acid secretion-promoting functional shell can not only improve the calcium absorption efficiency, but also improve the overall digestion and nutritional status of animals. It is an innovative technical solution with practical application value.

[0156] In addition, it should be noted that animals, such as cats and dogs, usually swallow their staple food, feed and / or snacks. They do not chew slowly like humans, but tend to swallow the food whole or in large mouthfuls. This way of eating is related to their physiological structure and evolutionary history. The reasons are:

[0157] Tooth structure: The tooth structure of animals such as cats and dogs is adapted to tearing and cutting meat food. Their canines and carnassial teeth are very suitable for catching and tearing prey, while molars are used to bite off large pieces of food.

[0158] Saliva composition: Compared with humans, dogs and cats have less salivary amylase in their saliva, which means that they have limited ability to digest carbohydrates (such as starch) in their food and rely more on stomach acid and intestinal digestion.

[0159] Feeding behavior: The feeding behavior of dogs and cats is usually rapid, and they will swallow their food quickly, which may be due to the need to eat quickly in the wild to avoid predators or competitors.

[0160] Digestive efficiency: The digestive systems of dogs and cats are adapted to high-protein diets. Their stomachs can quickly secrete gastric acid when they come into contact with protein, which helps to break down the protein in food, while the intestines can quickly absorb nutrients.

[0161] Food form: Many feeds and snacks designed for dogs and cats are in easy-to-swallow forms, such as small pellets or easy-to-bite bars, to suit their eating habits.

[0162] Intestinal microorganisms: The intestinal microbial communities of dogs and cats are different from those of humans. They can break down and ferment certain components of food, such as protein and fat, but their ability to break down cellulose is weaker.

[0163] Nutrient absorption: Although dogs and cats mainly swallow food, their gastrointestinal structure and the secretion of digestive enzymes can still effectively absorb nutrients in food, including minerals such as calcium.

[0164] Feed processing: Taking into account the eating habits of dogs and cats, pet food manufacturers use special processing techniques to ensure that the nutrients in the food (such as inorganic calcium) can be effectively released and absorbed in the digestive tract of dogs and cats.

[0165] To sum up, although the way animals such as cats and dogs eat is different from that of humans, their physiological structure and digestive system have adapted to this way of swallowing food and can effectively absorb the required nutrients.

[0166] In the embodiments of the present application, in view of the dietary habits and feeding habits of animals, and taking into account the fact that the animals are fasting or other conditions that cause the stomach to not produce sufficient gastric acid, the form of the animal calcium supplement product is set to composite sandwich particles, including a calcium supplement core and a gastric acid secretion-promoting functional shell, wherein the calcium supplement core is used as a core material, and the gastric acid secretion-promoting functional shell is used as a coating material, which is coated on the outer surface of the calcium supplement core. After the animal swallows the animal calcium supplement product in the present application, the composite sandwich particles directly enter the stomach through the esophagus as a whole, and the gastric acid secretion-promoting functional shell of the composite sandwich particles directly contacts the gastric mucosa, thereby promoting the animal's stomach to produce a large amount of gastric acid. After dissolving and decomposing the gastric acid secretion-promoting functional shell, the gastric acid directly contacts and infiltrates the inorganic calcium in the calcium supplement core, i.e., calcium hydrogen phosphate, and decomposes, producing the above-mentioned reactions (1) and (2), thereby decomposing the calcium bicarbonate to produce Ca 2+ , and then enter the Ca 2+ The decomposition, absorption and utilization process.

[0167] Even if some of the composite sandwich particles are broken by animals, firstly, according to the eating habits of animals, most of the composite sandwich particles will be swallowed directly, and only a small part will be broken, which will not affect the calcium supplement effect; secondly, the calcium supplement core and the gastric acid secretion-promoting functional shell of the crushed composite sandwich particles will also enter the stomach of the animal, and the gastric acid secretion-promoting functional shell will also directly contact the surface of the animal's gastric mucosa, which will also stimulate the stomach to instantly secrete a large amount of gastric acid for decomposition, and will also not affect the decomposition of inorganic calcium, as well as the absorption of calcium and the efficiency of calcium supplementation.

[0168] Furthermore, the gastric acid secretion promoting shell comprises the following components:

[0169] Meat meal, starch, animal fat and thickeners;

[0170] The above-mentioned gastric acid secretion promoting functional shell includes a plurality of different components, through which the components play a certain role in promoting gastric acid secretion:

[0171] (1) Meat powder: The protein content of meat powder can stimulate the G cells in the stomach to produce gastrin after contacting the gastric mucosa. Gastrin is a powerful stimulating factor for gastric acid secretion. In addition, protein decomposition products can also directly stimulate gastric acid secretion.

[0172] It should be noted that when food containing animal protein enters the stomach, specific receptors on the gastric mucosa can sense the presence of protein and send signals to the brain through the vagus nerve. The brain then sends signals to the stomach through the vagus nerve to stimulate the gastric wall cells to secrete gastric acid.

[0173] (2) Animal oils: Animal fats and oils can stimulate K cells in the stomach to secrete gastrin, thereby promoting the secretion of gastric acid. The fatty acids in animal oils, especially those that can activate gastrin receptors in the stomach, can promote the secretion of gastric acid.

[0174] It should be noted that fats and oils can slow down the emptying of the stomach, making food stay in the stomach longer, which helps to continuously stimulate the secretion of gastric acid. In addition, some fatty acids, especially those that can activate specific receptors in the stomach, can also promote the secretion of gastric acid.

[0175] (3) Starch: As a carbohydrate, starch’s decomposition products can also indirectly affect gastric acid secretion. Although starch itself does not have as significant direct effect on gastric acid secretion as protein and fat, it can be used as part of the overall food composition and work together with other ingredients to affect gastric emptying rate and gastric acid secretion.

[0176] (4) Thickeners: Thickeners such as pectin, gellan gum, and sodium carboxymethyl cellulose can be used to adjust the viscosity and stability of the shell. Although their direct effect on gastric acid secretion is still unclear, they help control the dissolution rate of the shell, which may indirectly affect the contact time between food and gastric mucosa and the release of gastrin.

[0177] Combining the effects of these components, the design of the gastric acid secretion promoting functional shell can promote gastric acid secretion in the following ways:

[0178] Quick response: The combination of meat meal and animal oil can quickly stimulate gastric acid secretion, providing a timely acidic environment for the dissociation and absorption of calcium salts.

[0179] Sustained effect: The addition of animal oil can slow down the rate of gastric emptying and prolong the residence time of food in the stomach, thereby achieving continuous stimulation of gastric acid secretion.

[0180] Adaptability: By adjusting the types and proportions of meat meal and animal oil, it can adapt to the digestive physiological characteristics and nutritional needs of different animals.

[0181] Protective Mechanism: Starches and thickeners may help protect the core calcium supplement while indirectly regulating the rate and duration of gastric acid secretion by controlling the dissolution rate of the outer shell.

[0182] The advantage of this design is that it can provide animals with an environment that promotes gastric acid secretion, thereby improving the dissociation and absorption efficiency of inorganic calcium salts such as calcium hydrogen phosphate, while also taking into account the overall nutritional and digestive health of the animal.

[0183] Further, the meat meal includes at least one of beef meal, mutton meal and chicken meal;

[0184] As mentioned above, meat powder from different sources (beef powder, mutton powder, chicken powder), as high-quality animal protein, can not only stimulate the secretion of gastric acid after contacting the gastric mucosa, but also have different flavors, which can improve the taste of calcium supplement products and improve the palatability of animals.

[0185] Further, the starch includes at least one of potato starch, corn starch and wheat starch;

[0186] As mentioned above, different types of starch (potato starch, corn starch, wheat starch) have different digestion rates and gastric emptying rate effects. By properly selecting the type of starch, the gastric emptying rate can be adjusted, thereby affecting the secretion of gastric acid and the digestion time of food in the stomach.

[0187] Further, the animal oil includes at least one of chicken oil, fish oil, beef tallow and duck oil;

[0188] As mentioned above, different animal oils can adapt to the digestive characteristics of different animals: different animals may have better digestion ability for specific types of proteins and fats. For example, ruminants may be more adapted to beef tallow, while carnivorous animals may be more adapted to fish oil. By providing a variety of meat meals and animal oil options, products can be customized for different types of animals to improve calcium absorption and product adaptability. In addition, animal oils not only promote gastric acid secretion, but also provide essential fatty acids and energy, which helps maintain the overall nutritional balance of animals.

[0189] Furthermore, the thickener includes at least one of pectin, gellan gum and sodium carboxymethyl cellulose.

[0190] Furthermore, the gastric acid secretion promoting functional shell includes the following components in parts by weight: 60 to 90 parts of meat powder; 3 to 30 parts of starch; 1 to 10 parts of animal oil; and 0.2 to 2 parts of thickener.

[0191] For further reference, Figure 3The animal calcium supplement product provided in the embodiment of the present application is a composite sandwich particle, which includes two parts: a calcium supplement core and a gastric acid secretion promoting functional shell. The gastric acid secretion promoting functional shell includes a shell and at least one strip-shaped groove arranged on the surface of the shell.

[0192] For further reference, Figure 4 In A, the outer surface of the shell of the gastric acid secretion promoting functional shell of each of the composite sandwich particles is provided with a plurality of strip-shaped grooves.

[0193] Furthermore, a plurality of strip-shaped grooves are arranged in parallel on the outer surface of the shell of the gastric acid secretion promoting functional shell of the composite sandwich particle.

[0194] It should be noted that the gastrointestinal structure of animals such as dogs and cats is somewhat different from that of humans, and these differences will affect the absorption efficiency of inorganic calcium (such as calcium bicarbonate) in conventional calcium supplement products to a certain extent. The following are some influencing factors (taking dogs and cats as an example):

[0195] Stomach morphology and gastric acid secretion: Dogs have a single-chamber stomach with a strong ability to secrete gastric acid. Cats have a pear-shaped sac-like stomach with relatively active gastric acid secretion. In theory, this is conducive to the reaction of inorganic calcium with gastric acid, promoting its dissociation into absorbable calcium ions.

[0196] Intestinal length and structure: Dogs have shorter intestines, which are 5 times their body length, with an average small intestine length of 4 meters. Cats have relatively short and wide intestines, thick intestinal walls, and strong digestive capacity. This means that food passes through the intestines of dogs and cats faster. If gastric acid secretion is insufficient or food passes through the stomach quickly after ingestion, inorganic calcium may not have enough time to react with gastric acid and be excreted from the body.

[0197] Food intake habits: Dogs and cats usually eat in a hurry and are not good at chewing, which may lead to insufficient mixing of food in the mouth and affect the contact and reaction between gastric acid and inorganic calcium.

[0198] The form of calcium supplements: The form (such as granules, powder or liquid) and dosage of calcium supplements may also affect the absorption efficiency of calcium. Smaller particle size or liquid form helps increase the contact area between inorganic calcium and stomach acid, thereby improving absorption efficiency.

[0199] Influence of other nutrients: Dogs and cats have a strong ability to digest protein and fat, and the metabolites of these nutrients may affect the absorption of calcium. For example, the amino acids produced by protein digestion may form soluble complexes with calcium, which helps calcium absorption.

[0200] In summary, the gastrointestinal structure of dogs and cats may affect the absorption efficiency of inorganic calcium bicarbonate, but this mainly depends on many factors, including gastric acid secretion, intestinal length and structure, food intake habits, and the form of calcium supplements.

[0201] In the present technology, for animals such as dogs and cats, which eat very quickly, after the animal calcium supplement product enters the esophagus, due to the animal's own physiological structure, the particles may be directly discharged into the intestine without producing enough gastric acid, decomposing or reacting completely, thereby causing direct loss of calcium. In order to improve the efficiency of calcium supplementation, the above factors are taken into consideration in the embodiments of the present application, and the structure of the animal calcium supplement product is improved.

[0202] In animal calcium supplement products, the particles are designed as composite sandwich particles, including a calcium supplement core and a gastric acid secretion-promoting shell with a specific surface structure. This design has multiple purposes, functions and advantages:

[0203] (1) Increasing surface area: Providing strip-shaped grooves on the shell surface can increase the surface area of ​​the overall particles, thereby providing more contact surfaces to promote gastric acid secretion.

[0204] (2) Improved dissolution rate: The strip-shaped groove design helps the shell dissolve faster, allowing the gastric acid secretion-promoting ingredients (such as meat powder, starch, animal oil and thickener) to contact the gastric mucosa more quickly, thereby accelerating gastric acid secretion.

[0205] (3) Controlled release: Multiple parallel strip grooves can control the release rate of gastric acid secretion promoting components, ensuring continuous and stable gastric acid secretion to support calcium absorption.

[0206] (4) Enhanced mechanical strength: The wavy or zigzag grooves can enhance the mechanical strength of the shell, making it more stable and less prone to breakage during processing and storage.

[0207] In addition, in the composite sandwich particles of animal calcium supplement products, the shell surface is designed with multiple strip-shaped grooves, which have the following potential effects on the fluidity of the particles in the animal body, the wall adhesion effect, and the contact mode with the gastric mucosa:

[0208] (1) Reduced flowability: The groove design may increase the friction between particles, thereby reducing their flowability in the animal digestive tract. This effect of reducing flowability may help the particles stay in the stomach longer.

[0209] (2) Enhanced wall-hanging effect: The strip-shaped grooves can provide a mechanical hooking effect, making it easier for the particles to adhere to the stomach wall. This wall-hanging effect helps the particles to contact the gastric mucosa and increase gastric acid secretion.

[0210] (3) Delayed transfer to the intestine: Because the particles stick to the stomach wall and come into contact with the gastric mucosa, the time it takes for the particles to transfer from the stomach to the intestine is delayed, thus providing more time for calcium absorption.

[0211] (4) Improved absorption efficiency: By increasing the contact time and surface area with the gastric mucosa, the dissociation and absorption efficiency of calcium hydrogen phosphate in the calcium supplement core can be improved.

[0212] (5) Reduce gastric discomfort: The groove design may help reduce the accumulation of particles in the stomach, reducing the risk of gastric discomfort or obstruction.

[0213] In summary, the design of multiple strip-shaped grooves on the surface of the particles is intended to improve the effect of the particles in the animal's stomach, increase the efficiency of calcium supplementation, and ensure the safety of the product and the comfort of the animals.

[0214] For further reference, Figure 4 In C, the plurality of parallel strip-shaped grooves are arranged in a wave shape on the outer surface of the shell of the gastric acid secretion promoting functional shell of the composite sandwich particle.

[0215] The plurality of wavy strip-shaped grooves are parallel to each other, so that more grooves formed by wavy lines are presented on the surface of the composite sandwich particle, thereby further increasing the contact surface area.

[0216] For further reference, Figure 4 In D, the plurality of parallel strip-shaped grooves are arranged in a zigzag shape on the outer surface of the shell of the gastric acid secretion promoting functional shell of the composite sandwich particle.

[0217] As mentioned above, on the shell surface, a plurality of strip-shaped grooves are arranged in a zigzag shape, for example, a zigzag shape formed by broken lines, or a zigzag shape formed by connecting the ends of a rectangular frame with an opening, thereby greatly increasing the surface area of ​​the particle surface in contact with the gastric mucosa.

[0218] For further reference, Figure 4 In B, the strip-shaped grooves include linear grooves and cross grooves intersecting the linear grooves;

[0219] Both ends of the linear groove extend to the head and tail ends of the composite sandwich particle, and at least one of the cross grooves crosses the linear groove.

[0220] As mentioned above, in order to further increase the contact area between the particles and the body fluids and gastric juices in the gastric mucosa and accelerate the production of gastric acid, in the embodiment of the present application, grooves in two directions can be set on the surface of the strip groove, namely linear grooves and cross grooves. The linear grooves can be longer grooves connecting the head and tail ends of the particles, while the cross grooves can be grooves connected to and intersecting the linear grooves, or continuously intersecting.

[0221] For example, the particle is a rectangular particle in a top view, having a length direction, including an upper surface and a lower surface, and the length directions of the upper surface and the lower surface are each provided with three parallel wavy linear grooves connecting the head and tail ends; and each side surface is provided with three cross grooves that intersect with the linear grooves, and the cross grooves on each side surface are parallel to each other.

[0222] By providing the cross grooves, the surface area of ​​the particles in contact with the gastric mucosa is further increased, the production of gastric acid is accelerated, and the decomposition efficiency of calcium ions is improved.

[0223] For further reference, Figure 5 The inner surfaces of the strip-shaped grooves of the composite sandwich particles are coated with an animal oil layer, and freeze-dried meat powder adheres to the surface of the animal oil layer.

[0224] In order to further improve the palatability, the inner surface of the strip groove of each composite sandwich particle is coated with animal oil, and then freeze-dried meat powder is adhered to the animal oil. The freeze-dried meat powder may include but is not limited to chicken powder, beef powder, pork powder, etc., and may be the same component as the aforementioned meat powder, but the processing method is freeze-dried meat powder.

[0225] After the animal oil is applied, an animal oil layer is formed, and the freeze-dried meat powder can adhere to the inner surface of the strip groove, and because the strip groove is groove-shaped, the freeze-dried meat powder can be more firmly embedded therein, and will not fall off later due to the smooth surface. The animal oil can be the same as the animal oil in the aforementioned calcium supplement core and gastric acid secretion promoting functional surgery, or it can be different.

[0226] As mentioned above, compared with conventional particles with certain defects or holes on the surface, the composite sandwich particles provided in the embodiments of the present application increase the contact area with the gastric mucosa through the strip groove design on the shell, which may promote the wall hanging effect, so that the particles stay in the stomach for a longer time, thereby prolonging the release and absorption process of calcium. The groove design provides more contact points, which helps the particles to better contact with the gastric mucosa and promote the secretion of gastric acid in local areas. This may be more effective than a smooth surface or a simple hole structure. Due to the promotion of gastric acid secretion and the extension of the residence time in the stomach, the particles of this technology can increase the residence time by hanging on the wall and adhering to the stomach wall, thereby improving the absorption efficiency of calcium. The shell in the composite sandwich design can protect the calcium supplement core from the external environment. When biting, chewing or swallowing, it can protect the calcium supplement core as much as possible until the particles enter the stomach and contact with gastric acid, which helps to maintain the stability and activity of the calcium supplement component, and better promote gastric acid secretion in the first place; the strip groove provides a structural optimization, which may help to improve the mechanical strength and crushing resistance of the particles, while the traditional defect or hole structure may make the particles more fragile.

[0227] As mentioned above, the grooves coated with animal oil and adhered with freeze-dried meat powder may increase the attractiveness of the particles, improve the palatability and appetite of animals by improving the taste and flavor. The special coating and adhesion on the inner surface of the groove may help control the release rate of the calcium supplement ingredients and achieve a more stable and sustained calcium supplement effect.

[0228] Since freeze-dried meat powder is a freeze-dried powder, it can adhere firmly to the strip-shaped grooves. Compared with the conventional granular feed mixed with meat powder or freeze-dried powder on the market, which is just a mixture of finished feed particles and freeze-dried powder and packaged for sale, there is no synergistic effect between the two, and the two are not tightly combined. When taken out, there are only particles with a small amount of powder adhered to them, and a large amount of remaining debris, crumbs, dust, and freeze-dried residue, which makes it difficult to four-dimensional and causes waste.

[0229] In the present technology, animal oil acts as an adhesive to adhere the freeze-dried powder to the strip-shaped grooves during the preparation process. However, there is no separately coated animal oil at other locations on the outer surface of the particle shell, so the freeze-dried powder will not adhere to other locations.

[0230] In summary, in the embodiments of the present application, a potentially more effective, safer, and more popular calcium supplementation method for animals is provided through an innovative composite sandwich particle design, aiming to improve the overall performance and user experience of calcium supplement products.

[0231] refer to Figure 6 In the embodiments of the present application, a method for preparing the animal calcium supplement product as described above is also provided, comprising:

[0232] Step S1, preparing mixed wet material;

[0233] Step S2, forming the mixed wet material into strips;

[0234] Step S3, steaming the strips and cutting them into wet granules;

[0235] Step S4, drying the wet granules to obtain the animal calcium supplement product;

[0236] Furthermore, the step of making the mixed wet material into a strip-shaped object comprises: placing the mixed wet material into a strip-shaped material production device to prepare the strip-shaped object;

[0237] Furthermore, the temperature of the steaming treatment is 85°C to 95°C;

[0238] Furthermore, the steaming process lasts for 20 to 30 minutes.

[0239] It should be noted that steaming is an important step in the preparation of animal calcium supplement products, which has the following purposes and functions:

[0240] Sterilization: The high temperature during the steaming process can kill the microorganisms that may exist on the surface and inside the particles, ensuring the hygiene and safety of the product.

[0241] Promote gelation: During the steaming process, collagen and other high molecular substances will gel after being heated to form a stable structure, which helps to enhance the stability and mechanical strength of the particles.

[0242] Improved structure: Steaming helps to form a fixed structure inside the particles, so that the dried particles have good rehydration and stability.

[0243] Promote starch gelatinization: Starch gelatinizes when heated to form a stable gel-like structure, which helps improve the taste and digestibility of the particles.

[0244] Fixing shape: Steaming can initially fix the shape of the particles, making it easier to cut and dry them.

[0245] Promote component fusion: At high temperatures, the components in the coating material and the core material can be better fused, bonded, and combined to form complete and highly stable particles.

[0246] Improve drying efficiency: Steamed pellets can remove moisture faster during the drying process, improving drying efficiency.

[0247] Improved taste: Steaming helps improve the taste of pellets, making them more palatable to animals.

[0248] Enhanced nutrient retention: Appropriate steaming time can preserve the nutrients in the raw materials to the greatest extent and avoid nutrient loss caused by long-term high-temperature treatment.

[0249] Easy to handle: Steamed pellets are easier to cut and dry, which helps improve the efficiency of the production line.

[0250] The steaming step ensures that the animal calcium supplement granules maintain their nutritional content while having good physical and chemical stability, as well as a taste and structure suitable for pet consumption.

[0251] Furthermore, the drying process is freeze-drying process; the conditions of the freeze-drying process include:

[0252] Freezing temperature: -50℃~-40℃; Freezing time: at least 24 hours;

[0253] Furthermore, the freeze drying equipment of the freeze drying process is set up with the following conditions: cold trap temperature is -45°C; heating rate is 10°C / h; final temperature is 60°C; vacuum degree is 10-70Pa;

[0254] Furthermore, during the freeze-drying process, the moisture content of the animal calcium supplement product is controlled to be between 2% and 5%.

[0255] As described above, the animal calcium supplement product is prepared by freeze drying (lyophilization) to have the following advantages:

[0256] Preserve active ingredients: Freeze drying is a gentle drying process that removes moisture at low temperatures, thereby preserving the active ingredients in the product, such as vitamins, enzymes and proteins, to the greatest extent possible.

[0257] Extending shelf life: Freeze drying can significantly extend the shelf life of animal calcium supplement products - composite sandwich particles by removing moisture from the product, as moisture is a key factor in microbial growth.

[0258] Maintaining structural integrity: During freeze-drying, ice crystals change directly from solid to gaseous state during sublimation, leaving behind the original pore structure, which helps maintain the structural integrity of the particles.

[0259] Easy to store and transport: Freeze-dried particles are light in weight and small in size, making them easy to store and transport without the need for refrigeration.

[0260] Provide a variety of administration methods, such as direct administration or rapid rehydration: Among them, freeze-dried products have good rehydration properties and can quickly absorb water to return to a near-original state, making it easier for managers (such as owners, breeders or veterinarians) to administer the drug.

[0261] Improved taste and flavor: Freeze drying helps maintain the taste and flavor of the product, avoiding flavor changes that may occur during high-temperature drying.

[0262] Reduce oxidation: During the freeze-drying process, due to the low temperature and vacuum environment, the oxidation of active ingredients can be reduced, maintaining the nutritional value and quality of the product.

[0263] Improved safety: Freeze drying improves product safety by removing moisture that could cause bacterial growth.

[0264] Easy to control dosage: Freeze-dried particles are easy to weigh accurately, making it easier for managers to control dosage according to the needs of animals.

[0265] Suitable for multiple uses: Freeze-dried pellets can be used directly as a stand-alone product or as a functional ingredient added to regular animal food.

[0266] In summary, freeze-drying is an effective processing method that can maintain the nutritional content of animal calcium supplement products-composite sandwich particles, improve product stability, and provide convenient storage and use.

[0267] Further, the mixed wet material includes calcium-supplemented core wet material;

[0268] The preparation method of the calcium-supplemented core wet material comprises:

[0269] Calcium hydrogen phosphate, milk calcium, natural plant products, lactose-free milk powder, animal oil, animal hydrolyzate, fructooligosaccharide, casein phosphopeptide, thickener, microbial fermentation product, L-lysine hydrochloride, collagen, preservative, natural antioxidant, vitamin D3, and water are mixed and heat-treated to obtain the calcium supplement core wet material.

[0270] As mentioned above, the mixing device may be a blender, a homogenizing device, etc., and may also be other mixing devices.

[0271] Furthermore, the calcium hydrogen phosphate, milk calcium, natural plant products, lactose-free milk powder, animal oil, animal hydrolyzate, fructooligosaccharide, casein phosphopeptide, thickener, microbial fermentation product, L-lysine hydrochloride, collagen, preservative, natural antioxidant, vitamin D3, and water are mixed and heat-treated to obtain the calcium supplement core wet material, including:

[0272] Based on a unit dose of 100 parts, 2 to 20 parts of calcium hydrogen phosphate, 2 to 20 parts of milk calcium, 1 to 10 parts of natural plant products, 1 to 10 parts of lactose-free milk powder, 1 to 10 parts of animal oil, 1 to 10 parts of animal hydrolyzate, 1 to 10 parts of fructooligosaccharide, 0.5 to 5 parts of casein phosphopeptide, 0.5 to 5 parts of microbial fermentation products, 0.5 to 5 parts of L-lysine hydrochloride, 0.05 to 0.5 parts of preservatives, 0.05 to 0.5 parts of natural antioxidants, 0.005 to 0.1 parts of vitamin D3, and water are mixed to obtain a core slurry;

[0273] In the core slurry, 0.5 to 5 parts of thickener are added and mixed, and the mixture is heated to 70° C. to 80° C., and then 0.05 to 0.5 parts of collagen are added, and the mixture is heated to boiling. After cooling, the calcium-supplemented core wet material is obtained.

[0274] Furthermore, the mixed wet material also includes a shell wet material with the function of promoting gastric acid secretion;

[0275] The preparation method of the gastric acid secretion promoting shell wet material comprises:

[0276] Mixing meat powder, starch, animal oil, thickener and water to obtain the gastric acid secretion promoting shell wet material;

[0277] As mentioned above, the mixing device may be a blender, a homogenizing device, etc., and may also be other mixing devices.

[0278] Furthermore, the meat powder, starch, animal oil, thickener, and water are mixed to obtain the gastric acid secretion promoting shell wet material, including:

[0279] Based on a unit dose of 100 parts, 60 to 90 parts of meat powder, 3 to 30 parts of starch, 1 to 10 parts of animal oil, 0.2 to 2 parts of thickener, and water are mixed to obtain the wet shell material with the function of promoting gastric acid secretion.

[0280] Furthermore, the step of forming the mixed wet material into strips comprises:

[0281] The gastric acid secretion promoting function shell wet material and the calcium supplementing core wet material are placed in two strip material production devices respectively, and the strip material sandwiched by the gastric acid secretion promoting function shell wet material and the calcium supplementing core wet material is extruded simultaneously;

[0282] Furthermore, in the strip, the diameter of the calcium-supplemented core wet material is 0.5 cm;

[0283] Furthermore, in the strip, the outer diameter of the wet material of the gastric acid secretion promoting shell is 0.7 cm.

[0284] The strip material production equipment mentioned above may be an extruder or other equipment for producing strip materials.

[0285] In the above-mentioned step S2, in the process of making the mixed wet material into a strip, a strip groove processing device is also provided on the strip material production device, for example, it can be installed at the strip output port of the extruder.

[0286] The strip groove processing equipment may be provided with a strip groove processing device, and the prepared particles have linear grooves in the strip grooves. In addition, the strip groove processing device may be controlled by an algorithm setting, so that both linear grooves and cross grooves can be produced at the same time. Alternatively, the strip groove processing equipment may be provided with a strip groove processing device and a cross groove processing device to work together, so that the prepared particles have both linear grooves and cross grooves.

[0287] Wherein, the strip groove processing equipment may include a strip groove processing device, a first horizontal moving rail, a first telescopic rod, a first horizontal moving motor, a first telescopic motor, a cross groove processing device, a second horizontal moving rail, a second telescopic rod, a second horizontal moving motor, a second telescopic motor and a fixing device;

[0288] The strip groove processing device is connected to the first telescopic rod, and the other end of the first telescopic rod is connected to the first horizontal moving rail. Driven by the first horizontal moving motor, the first telescopic rod drives the strip groove processing device to reciprocate along the length direction of the first horizontal moving rail, so as to engrave a linear groove on the surface of the strip under controllable conditions; the first telescopic rod moves in the vertical direction under the control of the first telescopic motor, so as to control the length of the engraved line.

[0289] The cross groove processing device is connected to the second telescopic rod, and the other end of the second telescopic rod is connected to the second horizontal moving rail. Driven by the second horizontal moving motor, the second telescopic rod drives the strip groove processing device to reciprocate along the length direction of the second horizontal moving rail, so as to engrave a cross groove intersecting with the linear groove on the surface of the strip under controllable conditions; the second telescopic rod moves in the vertical direction under the control of the second telescopic motor, so as to control the length of the engraved line.

[0290] Further, the strip groove processing device and the cross groove processing device can be scrapers with a certain tooth-like structure, and the tooth pitch and tooth length can be adjusted. The structure for adjusting the pitch can be a conventional adjusting structure. For example, multiple tooth-like scrapers are arranged in parallel on the adjusting frame, and a connecting structure is provided between the tooth-like scrapers. By pushing one of the scrapers through a knob or a pull rod, etc., the pitch between all the tooth-like scrapers can be adjusted.

[0291] In addition, in the strip groove processing device and the cross groove processing device, an animal oil release device is further included, so that the animal oil flows onto the tooth-like scraper, and then when opening the strip-shaped groove, the animal oil is coated on the inner surface of the strip-shaped groove.

[0292] In step S4, after drying the wet particles, the dried particles are put into the freeze-dried meat powder for tumbling mixing, and then sieved, so that the freeze-dried meat powder adheres to the strip-shaped groove, and the freeze-dried meat powder at other positions on the surface of the particles is shaken off, thus completing the preparation.

[0362] Comparative test experiment:

[0363] 1. Test experiment 1: Investigation of growth and development status:

[0364] (1) Experimental methods:

[0365] Experimental animals: In this study, 80 weaned SD rats of about 4 weeks old were used, with an approximate weight range of 90 g to 110 g of the same sex (male). The experimental animals were healthy in clinical examination and had similar physical conditions. Ten rats were considered as a group, with a total of 8 groups. In order to improve the accuracy of the study and reduce errors in the study and avoid competition for food, the rats were kept in separate metal cages during meals.

[0366] Grouping: The rats were divided into 8 test groups. For groups 1 to 6, mixed feed was used for mixed feeding, and the rats were allowed to eat freely; wherein the mixed feed was obtained by premixing the feeds in Examples 1 to 6 with the feeds in Comparative Example 1 at a final calcium content of 0.5%. For group 7, the rats were fed with the feed in Comparative Example 1 and allowed to eat freely; for group 8, the rats were fed with the feed in Comparative Example 2 and allowed to eat freely.

[0367] During this period, rats in each experimental group were provided with fresh and free deionized water as drinking water to avoid obtaining calcium from drinking water.

[0368] From the beginning to the end of the experiment, the body weight of rats in each experimental group was measured every week for a total of 5 times during 4 weeks.

[0369] (2) Experimental results:

[0370] Table 6. Weight test results of different experimental groups

[0371]

[0372] In the above table, compared with groups 1 to 6: b, P < 0.05; compared with group 8: c, P < 0.05.

[0373] As shown in Table 6, at the end of the experiment, the weight of rats in group 7 was significantly lower than that of rats in group 8 (p < 0.05), and the weight of rats in group 8 was significantly lower than that of rats in groups 1 to 6 (p < 0.05), while there was no significant difference in weight between groups 1 to 6 (p > 0.05), indicating that calcium deficiency caused malnutrition in rats and slow weight gain. The experimental group supplemented with both inorganic and organic calcium was relatively higher than the experimental group supplemented with inorganic calcium alone, indicating that the addition of organic calcium sources can improve the overall absorption efficiency of calcium supplement products and lead to better development.

[0374] 2. Test experiment 2: Investigation of calcium ion metabolism.

[0375] (1) Experimental methods:

[0376] Based on the experiment in test experiment 1, the metabolic test was started after 21 days of the experiment. The food intake was recorded for 3 days and feces were collected for 72 hours. The calcium content in the feed and feces was determined, and the apparent calcium absorption rate was calculated.

[0377] Calcium intake (mg / d) = calcium content in feed (mg / g) × feed consumption (g / d);

[0378] Fecal calcium (mg / d) = fecal calcium content (mg / g) × fecal excretion (g / d);

[0379]

[0383] In the above table, calcium intake: compared with groups 4 to 6: b, P<0.05; compared with group 1: c, P<0.05; compared with groups 2 and 4: d, P<0.05; compared with group 6: e: P<0.05; fecal calcium: compared with group 8: b, P<0.05; compared with group 5: c, P<0.05; compared with group 4: d, P<0.05; compared with groups 3 and 6: e, P<0.05; apparent calcium absorption rate: compared with group 7: b, P<0.05; compared with group 6: c, P<0.05; compared with groups 1 to 5: d, P<0.05.

[0384] As can be seen from Table 7, the calcium intake and fecal calcium of rats in the low-calcium feed group (Comparative Example 1) were significantly lower than those in the other groups (p < 0.05), but the apparent calcium absorption rate was the highest (p < 0.05). This was due to the severe lack of calcium intake in this group, indicating that the calcium absorption rate of rats in a state of severe calcium deficiency will be significantly higher than the normal level, so as to improve the physiological condition of calcium deficiency in the body as soon as possible.

[0385] The calcium intake of groups 4 to 6 was significantly higher than that of groups 1 to 3, indicating that the shell covering the outer surface of the calcium supplement core can effectively promote gastric acid secretion, thereby further increasing the calcium intake of rats.

[0386] The apparent calcium absorption rates of groups 1 to 6 were significantly higher than those of group 8 (p < 0.05), indicating that the products prepared in Examples 1 to 6 not only contain milk calcium to provide calcium, but also contain other functional substances and functional structures that contribute to calcium absorption, thereby improving the overall calcium absorption efficiency. The calcium supplementation effects are significantly better than those of the simple inorganic calcium group.

[0387] The apparent calcium absorption rate of group 6 was significantly better than that of other groups, indicating that the strip-shaped grooves effectively improved the particle structure, increased the contact area between the gastrointestinal tract and the sample, stimulated gastric acid secretion, and thus facilitated the digestion and absorption of calcium by rats.

[0388] 3. Test experiment 3: blood biochemistry test.

[0389] (1) Experimental method: Based on the experiment in test experiment 1, blood was collected from each experimental group 3 weeks after the experiment using the rat tail blood collection method. Cut off about 0.2-0.3 cm of the tail tip and wipe off the first drop of blood. Then use a capillary to quantitatively draw tail blood, and use cotton balls to press and stop bleeding after blood collection. The amount of blood collected each time is 0.3-0.5 mL. The collected blood samples are transferred to a test tube containing EDTA anticoagulant, and then the changes in the content of major minerals (calcium and phosphorus) in the blood are analyzed using a fully automatic biochemical analyzer.

[0393] In the above table, blood calcium: compared with group 6: b, P<0.05; compared with group 3: c, P<0.05; compared with group 8: d, P<0.05; blood phosphorus: there was no significant difference between groups 1 to 8, P>0.05.

[0394] As shown in Table 8, the serum calcium of the rats in Group 7 was significantly lower than that of the other groups (p < 0.05), indicating that calcium deficiency can cause blood calcium content to be lower than normal levels, seriously affecting the growth and development of rats. Although the samples in Groups 1 to 6 and Group 8 can effectively maintain normal blood calcium levels, the serum calcium of the test group that consumed the calcium supplement product was significantly higher than that of the group that only added inorganic calcium (p < 0.05), indicating that the calcium supplement product in the embodiment can promote the absorption of calcium in rats better than inorganic calcium. There was no significant difference in serum phosphorus between the groups (p > 0.05), indicating that the body supplementation of calcium supplement products had no significant effect on serum phosphorus.

[0395] 4. Test experiment 4: Investigation of gastric juice secretion.

[0396] (1) Experimental method: Based on the experiment in test experiment 1, before the last test sample was consumed in each experimental group for 4 weeks, 3 rats were taken from each group for gastric juice secretion test, and they were fasted and deprived of water for 12 hours. Before the experiment, the rats were anesthetized intraperitoneally with sodium pentobarbital solution, the hair on the upper abdomen was cut off, an incision of about 3 cm long was made in the middle of the abdomen below the xiphoid process, the abdominal cavity was opened along the linea alba, and the wound was sutured with thread at the cardia. After the rats woke up, they were fed with the test samples of each experimental group. After 1 hour, the animals were killed, the abdomen was opened, the esophagus was clamped to remove the stomach, and the gastric juice was carefully collected and separated and the gastric juice volume (L) was recorded. The pH value of the obtained gastric juice was measured with a pH meter.

[0397] Gastric acid output (mmol) = NaOH concentration × NaOH consumption.

[0401] In the above table, gastric juice pH value: compared with groups 1 to 3: b, P < 0.05; gastric juice secretion: compared with groups 4 to 6: b, P < 0.05.

[0402] As shown in Table 9, the gastric juice pH value of rats in groups 4 to 6 was significantly lower than that in groups 1 to 3 (p < 0.05), and the gastric juice secretion of groups 4 to 6 was significantly higher than that of other groups (p < 0.05), indicating that the shell covering the outer surface of the calcium supplement core can effectively stimulate the gastric acid secretion function, increase the gastric juice secretion, significantly reduce the gastric juice pH value, and dissociate calcium through gastric acid, which is beneficial to the digestion and absorption of calcium.

[0403] 5. Test experiment 5: Palatability assessment.

[0404] (1) Experimental method: 30 adult domestic cats were selected for palatability test, and single bowl test was performed using samples of Examples 1 to 6, Comparative Example 1 and Comparative Example 2. 100 g of one of the samples of Groups 1 to 8 was placed in the feeding plate every day for 8 days. First, the weight of the test sample before feeding was measured within each 24 hours, and then the remaining weight of the test sample after feeding was measured, so as to calculate the feed intake (g / d) and feed intake rate (%) respectively by the following formulas.

[0405] Formula 1: Feed intake (g / d) = sample weight - sample remaining weight;

[0406] Formula 2:

[0410] In the above table, feed intake: compared with group 4: b, P<0.05; compared with groups 1 to 3: c, P<0.05; feed intake rate: compared with group 4: b, P<0.05; compared with group 1: c, P<0.05; compared with groups 2 to 3: d, P<0.05.

[0411] As shown in Table 10, the food intake and feeding rate of cats in Group 7 and Group 8 were significantly lower than those in other groups (p < 0.05), indicating that the calcium supplement product had a higher palatability.

[0412] In Examples 4 to 6, compared with Examples 1 to 3, the feed intake was relatively increased (p < 0.05), and the feed intake rate was also increased accordingly (p < 0.05), indicating that the shell coated on the outer surface of the calcium supplement core can effectively improve the palatability of calcium supplement products for domestic cats, which is beneficial to calcium intake.

[0413] There was no significant difference between groups 1 to 6 (p>0.05), indicating that cats have a higher palatability for calcium supplement products, which is more conducive to the animal's calcium intake, thereby supporting the animal's bone health, improving nutrient absorption efficiency, and enhancing the animal's overall health.

[0414] In summary, through animal experiments such as growth and development tests on rats, metabolic tests, blood biochemistry tests, gastric juice secretion tests, and palatability tests on cats, it is proved that the calcium supplement products of the six embodiments can significantly promote the weight gain of rats, significantly increase the calcium absorption rate and serum calcium level, and the shell coated on the outer surface of the calcium supplement core can effectively promote gastric acid secretion function, and the strip grooves on the calcium supplement particles effectively improve the particle structure and are beneficial to the digestion and absorption of calcium by rats. The calcium supplement effect of the calcium supplement product is significantly better than that of feed containing only inorganic calcium, and Example 6 is the best calcium supplement formula.

[0415] The above are preferred implementation modes and corresponding embodiments of the present invention. It should be pointed out that, for those skilled in the art, without departing from the creative concept of the present invention, several modifications and improvements may be made, including but not limited to the adjustment of proportions, processes, dosages and reaction vessels, which all fall within the scope of protection of the present invention.
