Description

Technical Field

[0001] The invention relates to the technical field of animal feed, in particular to a concentrated feed for piglets with growth-promoting properties using traditional Chinese medicine. Background Art

[0002] Piglets refer to piglets from birth to a weight of about 30 kilograms. During this stage, piglets grow and develop rapidly, have poor body temperature regulation function, and weak digestive ability. After a period of feeding and raising, piglets grow into adult pigs and are mainly used for meat production.

[0003] For example, CN104431605A involves a concentrated feed for promoting the healthy growth of piglets and a preparation method thereof, wherein the concentrated feed mainly comprises puffed soybeans, fish meal, second-rate flour, whey powder, milk replacer, calcium hydrogen phosphate, stone powder, salt, lysine, methionine, threonine, yeast selenium, choline chloride, multivitamins, multiminerals, quinolone, colistin sulfate, etc.; the concentrated feed provided by the invention is added with organic zinc and yeast selenium, and also with high-protein feed fish meal, whey powder, milk replacer and puffed soybean powder, which has reasonable nutrition, improves the absorption and utilization rate of feed, is green, organic, It is pollution-free; microecological preparations and acidifiers are also added, which is also beneficial to the intestinal health of piglets, improves the digestion and utilization rate of feed by piglets, and thus promotes the healthy growth of piglets. However, the concentrated feed also contains calcium hydrogen phosphate, which supplements calcium and phosphorus elements, but the problem is that calcium hydrogen phosphate has poor solubility, and the piglet's digestive system has limited ability to digest calcium hydrogen phosphate. Too much calcium hydrogen phosphate will affect intestinal peristalsis and digestive juice secretion, thereby interfering with the digestive system, causing piglets to have problems such as loss of appetite, loose stools, and diarrhea, which in turn affects the growth quality of piglets.

[0004] In order to promote the digestion and absorption of nutrients by piglets and ensure the growth quality, a concentrated feed for piglets with traditional Chinese medicine for promoting growth is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a concentrated feed for piglets with Chinese medicine for promoting growth, so as to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides a concentrated feed for piglets that promotes growth with traditional Chinese medicine, comprising the following raw materials in the following weight proportions:

[0007] 20-30% protein raw materials, 10-15% vegetable scraps, 3-5% whey powder, 4-7% vegetable oil, 1-3% chicken gizzard powder, 3-6% peach kernel, 6-9% composite acidulant, 2-5% monocalcium phosphate, 1-4% Shenqu, 1-3% bupleurum volatile oil, and the balance is water.

[0008] As a further improvement of the present technical solution, the protein raw materials include soybean meal, fish meal, meat and bone meal, peanut cake, silkworm pupa meal and sunflower meal, and the mass ratio of soybean meal, fish meal, meat and bone meal, peanut cake, silkworm pupa meal and sunflower meal is 4:4:3:1:3:2.

[0009] As a further improvement of the technical solution, the peanut cake is fermented peanut cake, and the sunflower meal is shelled sunflower meal.

[0010] As a further improvement of the technical solution, the vegetable scraps include potato peels, sweet potato leaves and radish leaves, wherein the mass ratio of potato peels, sweet potato leaves and radish leaves is 4:4:1.

[0011] As a further improvement of the present technical solution, the vegetable oil is canola oil or soybean oil.

[0012] As a further improvement of the technical solution, the composite acidulant includes potassium diformate, phosphoric acid and benzoic acid, and the mass ratio of potassium diformate, phosphoric acid and benzoic acid is 1:5:1.

[0013] As a further improvement of the technical solution, the mass proportion of the monocalcium phosphate in the concentrated piglet feed is one of 2.2%, 2.8% or 3.4%.

[0014] As a further improvement of the technical solution, the mass proportion of the chicken gizzard lining powder in the concentrated piglet feed is one of 1.2%, 1.8% or 2.7%, and the mass proportion of the peach kernel in the concentrated piglet feed is one of 3.5%, 4.1% or 5.5%.

[0015] As a further improvement of the technical solution, the bupleurum volatile oil is a volatile oily liquid extracted from the natural plant bupleurum.

[0016] As a further improvement of the technical solution, the mass proportion of the Bupleurum volatile oil in the concentrated piglet feed is one of 1.7%, 1.9% or 2.2%.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The concentrated feed for piglets using traditional Chinese medicine to promote growth uses vegetable scraps as feed to provide sufficient dietary fiber, which in turn promotes the growth of intestinal flora and the production of metabolites in piglets. Chicken gizzard powder and peach kernels are used to lubricate the intestines and promote intestinal wall peristalsis, thereby enhancing the intestinal health of piglets.

[0019] Calcium dihydrogen phosphate and bupleurum volatile oil are added to the feed. Calcium dihydrogen phosphate serves as a phosphorus source, and the phosphate ions produced by calcium dihydrogen phosphate in water can combine with free calcium to form calcium phosphate, which helps to increase the solubility of calcium and thus promote calcium absorption; Bupleurum volatile oil, with its ingredients such as myrtenol, can promote the intestinal development of piglets, and myrtenol containing hydroxyl functional groups can undergo esterification reaction with phosphoric acid to produce phosphate esters that can promote the bone development and growth of piglets, thereby ensuring the growth quality of piglets.

[0023] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not 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.

[0024] The present invention provides a concentrated feed for piglets with traditional Chinese medicine for promoting growth, comprising the following raw materials in proportion by weight:

[0025] 20-30% protein raw materials, 10-15% vegetable scraps, 3-5% whey powder, 4-7% vegetable oil, 1-3% chicken gizzard powder, 3-6% peach kernel, 6-9% composite acidulant, 2-5% monocalcium phosphate, 1-4% Shenqu, 1-3% bupleurum volatile oil, and the balance is water.

[0026] The above raw materials are weighed according to the proportion, crushed into powder, mixed and stirred with water, and finally concentrated to obtain concentrated piglet feed.

[0027] Among them, the protein raw materials include soybean meal, fish meal, meat and bone meal, peanut cake, silkworm pupa meal and sunflower meal, and the mass ratio of soybean meal, fish meal, meat and bone meal, peanut cake, silkworm pupa meal and sunflower meal is 4:4:3:1:3:2.

[0028] Protein is the basic substance that constitutes the body tissue of piglets, including muscles, bones, skin, hair, etc. Adequate protein supply can meet the growth and repair needs of piglet tissue cells and promote rapid growth of weight and body shape. Among them, the role of soybean meal is to provide high-quality protein, reduce feed costs, and improve digestion and absorption; fish meal is rich in lysine, tryptophan, methionine and cystine, which are nutritional amino acids required for the growth of piglets, and can promote muscle development and weight gain; meat and bone meal has a strong meaty aroma, which can improve the taste and flavor of feed, promote the appetite of piglets, increase food intake, and thus increase growth rate and weight; the protein in peanut cakes is easy to digest and absorb, which helps piglets better utilize the nutrients in feed; the nutrients in silkworm pupa powder can improve the meat quality of piglets, increase muscle content and tenderness of meat, and increase the nutritional value and edible quality of pork; oil sunflower meal is rich in protein and rich in a variety of essential amino acids, which can optimize the amino acid composition of feed and improve the nutritional value of feed.

[0029] The peanut cake is fermented peanut cake. After fermentation, the protein in the peanut cake is converted into small molecule peptides and free amino acids. The protein in these forms is easier to digest and absorb, thereby improving the protein absorption rate. The sunflower meal is shelled sunflower meal. Compared with the shelled sunflower meal, the shelled sunflower meal has a lower crude fiber content, making it easier to digest and absorb.

[0030] Vegetable scraps include potato peels, sweet potato leaves and radish leaves, among which the mass ratio of potato peels, sweet potato leaves and radish leaves is 4:4:1. Vegetable scraps refer to the parts of vegetables discarded during the processing process. Potato peels are rich in nutrients such as cellulose, minerals and vitamins, especially potassium, iron and other minerals. These ingredients have a positive effect on the growth and development and health maintenance of piglets. By adding potato peels, the volume of feed can be increased, and piglets can feel full, thereby reducing the intake of other feeds and improving the overall utilization of feed. In addition, the cellulose in potato peels can promote intestinal peristalsis and improve digestive function; the dietary fiber in sweet potato leaves helps promote intestinal peristalsis and prevent constipation in piglets; the cellulose in radish leaves can promote digestion in piglets and help them better absorb nutrients.

[0031] Vegetable oil is either canola oil or soybean oil. The unsaturated fatty acids in vegetable oil can reduce the deposition and accumulation of fat in pigs, promote the growth of lean meat, and increase the lean meat rate. Canola oil is oil extracted from canola seeds. The unsaturated fatty acids it contains can accelerate the decomposition and metabolism of fatty acids. Soybean oil is rich in high-energy fat. Adding it to pig feed can significantly increase the energy level of the feed.

[0032] The composite acidifier includes potassium diformate, phosphoric acid and benzoic acid, and the mass ratio of potassium diformate, phosphoric acid and benzoic acid is 1:5:1. Adding acidifier to feed can reduce the pH value in the pig's stomach and provide a more suitable working environment for digestive enzymes, thereby promoting food digestion and improving nutrient absorption rate. Among them, potassium diformate and benzoic acid can affect the proliferation of intestinal microorganisms, activate pepsinogen, improve the energy utilization rate of natural metabolites, improve animal absorption of protein, prevent diarrhea and diarrhea, and increase the survival rate and daily weight gain of piglets; phosphoric acid is a nutrient element necessary for bone growth. Piglets need a lot of phosphoric acid during the growth and development period to promote bone development and growth.

[0033] In piglet feed, calcium dihydrogen phosphate, as a phosphorus source, can improve the piglet's ability to resist diarrhea and stress, improve the piglet's survival rate, and enhance immunity. It can also increase the piglet's feed intake and promote growth and development by improving the palatability of the feed.

[0034] Chicken gizzard powder, as a good medicine in traditional Chinese medicine, one of its most significant effects is that it can promote the peristalsis of the small intestine. Combined with peach kernels rich in oil, it can lubricate the intestines, promote intestinal wall peristalsis, help piglets digest and absorb, and reduce the occurrence of constipation.

[0035] Bupleurum volatile oil is a volatile oily liquid extracted from the natural plant Bupleurum. The ingredients such as myrtenol contained in it can promote the intestinal development of piglets.

[0036] The following specific examples are used to further illustrate the concentrated piglet feed for promoting growth provided by traditional Chinese medicine provided by the present invention.

[0049] The peanut cake is fermented peanut cake, and the sunflower meal is shelled sunflower meal; the vegetable scraps include potato peels, sweet potato leaves and radish leaves, among which the mass ratio of potato peels, sweet potato leaves and radish leaves is 4:4:1.

[0050] The vegetable oil is canola oil; the composite acidulant includes potassium diformate, phosphoric acid and benzoic acid, and the mass ratio of potassium diformate, phosphoric acid and benzoic acid is 1:5:1; the bupleurum volatile oil is a volatile oily liquid extracted from the natural plant bupleurum.

[0051] Example 3

[0052] The purpose of this embodiment is to provide a concentrated feed for piglets with Chinese medicine for promoting growth, comprising the following raw materials in proportion by weight:

[0053] 30% protein raw materials, 10% vegetable scraps, 5% whey powder, 4% vegetable oil, 3% chicken gizzard powder, 3% peach kernel, 9% composite acidifier, 2% monocalcium phosphate, 4% Shenqu, 1% bupleurum volatile oil, and the balance is water.

[0054] The above raw materials are weighed according to the proportion, crushed into powder, mixed and stirred with water, and finally concentrated to obtain concentrated piglet feed.

[0055] Among them, the protein raw materials include soybean meal, fish meal, meat and bone meal, peanut cake, silkworm pupa meal and sunflower meal, and the mass ratio of soybean meal, fish meal, meat and bone meal, peanut cake, silkworm pupa meal and sunflower meal is 4:4:3:1:3:2.

[0056] The peanut cake is fermented peanut cake, and the sunflower meal is shelled sunflower meal; the vegetable scraps include potato peels, sweet potato leaves and radish leaves, among which the mass ratio of potato peels, sweet potato leaves and radish leaves is 4:4:1.

[0057] The vegetable oil is canola oil; the composite acidulant includes potassium diformate, phosphoric acid and benzoic acid, and the mass ratio of potassium diformate, phosphoric acid and benzoic acid is 1:5:1; the bupleurum volatile oil is a volatile oily liquid extracted from the natural plant bupleurum.

[0058] The effect test of the concentrated piglet feed prepared in Examples 1-3 was carried out. Since the growth rate of piglets is relatively fast, they generally start to gain weight immediately after birth, and the first month is the period when piglets grow fastest. In order to verify the growth-promoting effect of the concentrated piglet feed, this example selects two-month-old piglets as experimental subjects, feeds them with the concentrated piglet feed prepared in Examples 1-3, and records the weight changes of the piglets, and the average daily weight gain of the piglets is included in Table 1 (average daily weight gain = (piglet weight value after feeding-piglet weight value before feeding) / feeding days).

[0059] Table 1 Comparison of the average daily weight gain of piglets after feeding with the concentrated feed for piglets provided in Examples 1-3

[0060] Example 1 Example 2 Example 3 Average daily weight gain / g 176 203 181

[0061] According to Table 1, after feeding with the concentrated piglet feed prepared in Examples 1-3, the average daily weight gain of the piglets was higher than 176 g, which indicates that the concentrated piglet feed prepared in Examples 1-3 has a good growth-promoting effect.

[0062] The digestive system of piglets is not yet fully developed, and the secretion of digestive enzymes is relatively low, so indigestion is prone to occur. In the present invention, vegetable scraps are used as feed to provide sufficient dietary fiber, and then the dietary fiber is used to promote the growth of intestinal flora and the production of metabolites in piglets. Chicken gizzard powder and peach kernels are used to lubricate the intestines and promote intestinal wall peristalsis, thereby enhancing the intestinal health of piglets.

[0063] By adding calcium dihydrogen phosphate as a phosphorus source in the feed, the phosphate ions produced by calcium dihydrogen phosphate in water can combine with free calcium to form calcium phosphate, which helps to improve the solubility of calcium, thereby promoting calcium absorption. In addition, the volatile oil of Bupleurum chinense added to the feed can promote the intestinal development of piglets with its ingredients such as myrtenol, and myrtenol containing hydroxyl functional groups can undergo esterification reaction with phosphoric acid to produce phosphate esters that can promote the bone development and growth of piglets, thereby ensuring the growth quality of piglets.

[0064] Example 4

[0065] After weaning, the pH value in the stomach and intestines of piglets will change, gradually changing from the acidic environment during lactation to neutral or alkaline. The phosphate ions produced when calcium dihydrogen phosphate in the feed dissolves in water can help regulate this change and maintain normal acid-base balance in the intestine, thereby reducing the stress response caused by environmental changes.

[0066] In order to determine that the monocalcium phosphate component and the 2-5% mass proportion of monocalcium phosphate are one of the important factors that the concentrated piglet feed provided by the present invention can promote the growth of piglets, this embodiment, on the basis of the above-mentioned embodiment 2, only changes the mass proportion of monocalcium phosphate, and sets the mass proportion of monocalcium phosphate to 0%, 1.5%, 2.2%, 2.8%, 3.4% or 5.5%, and then prepares a concentrated piglet feed, and uses it for feeding piglets. According to the detection method for the average daily weight gain of piglets provided in the above-mentioned embodiment, the detection results are as follows: Figure 1 shown.

[0067] according to Figure 1 It can be seen that when the mass proportion of monocalcium phosphate is 0%, that is, when the concentrated piglet feed does not contain monocalcium phosphate, the average daily weight gain of the piglets is significantly reduced, indicating that monocalcium phosphate is one of the important components in the concentrated piglet feed that promotes the growth and development of piglets;

[0068] In addition, when the mass proportion of calcium dihydrogen phosphate in the prepared piglet concentrated feed is 1.5% or 5.5%, that is, the mass proportion of calcium dihydrogen phosphate is not 2-5%, the average daily weight gain of piglets is significantly lower than the average daily weight gain of piglets when the mass proportion of calcium dihydrogen phosphate in the prepared piglet concentrated feed is 2.2%, 2.8% or 3.4%.

[0069] This indicates that the monocalcium phosphate component and the 2-5% mass proportion of monocalcium phosphate are one of the important factors that enable the concentrated piglet feed provided by the present invention to promote the growth and development of piglets.

[0070] Example 5

[0071] The weaning stress after weaning causes a sudden drop in the level of digestive enzyme secretion in piglets, which reduces the digestive ability of piglets to feed. It takes 1-2 weeks to recover before it can increase again. The concentrated feed for piglets provided by the present invention adds chicken gizzard powder and peach kernels to help piglets digest, wherein:

[0072] Chicken gizzard powder is a powder made from the inner membrane layer of the chicken's internal organs after cleaning, drying, and grinding. It is rich in digestive enzymes, which can help piglets better digest the nutrients in the feed, improve the utilization rate of the feed, and thus promote the growth and development of piglets.

[0073] Peach kernels are rich in oil, which can stimulate gastrointestinal motility. Adding peach kernels and chicken gizzard powder to concentrated piglet feed can help promote gastrointestinal motility in piglets, prevent and relieve constipation, regulate the piglet's stomach, enhance its digestion and absorption capacity, and reduce intestinal problems such as diarrhea.

[0074] In order to verify that the compatibility of chicken's gizzard lining powder and peach kernel is one of the important factors that the concentrated piglet feed provided by the present invention can promote the growth of piglets, this embodiment, on the basis of the above-mentioned embodiment 2, only changes the mass proportion of chicken's gizzard lining powder and peach kernel, and sets the mass proportion of chicken's gizzard lining powder to 0%, 0.8%, 1.2%, 1.8%, 2.7% or 3.5%, and sets the mass proportion of peach kernel to 0%, 2.5%, 3.5%, 4.1%, 5.5% or 6.5%, and then prepares the concentrated piglet feed, and uses it for feeding piglets, and detects according to the detection method of the average daily weight gain of piglets provided in the above-mentioned embodiment, and the detection results are as follows: Figure 2 shown.

[0075] according to Figure 2 It can be seen that when the weight proportion of chicken gizzard powder is 0%, or the weight proportion of peach kernel is 0%, that is, when the concentrated feed for piglets does not contain chicken gizzard powder or peach kernel, the average daily weight gain of piglets is significantly reduced, indicating that the combination of chicken gizzard powder and peach kernel is one of the important factors in the concentrated feed for piglets to promote the growth and development of piglets;

[0076] In addition, when the weight proportion of chicken gizzard powder in the prepared concentrated piglet feed is 0.8% or 3.5%, that is, the weight proportion of chicken gizzard powder is not 1-3%, the average daily weight gain of piglets is significantly lower than the average daily weight gain of piglets when the weight proportion of chicken gizzard powder in the prepared concentrated piglet feed is 1.2%, 1.8% or 2.7%.

[0077] Moreover, when the mass proportion of peach kernels in the prepared piglet concentrated feed is 2.5% or 6.5%, that is, the mass proportion of peach kernels is not 3-6%, the average daily weight gain of piglets is significantly lower than the average daily weight gain of piglets when the mass proportion of peach kernels in the prepared piglet concentrated feed is 3.5%, 4.1% or 5.5%.

[0078] It can be explained that the 1-3% by weight proportion of chicken gizzard lining powder and the 3-6% by weight proportion of peach kernel are one of the important factors that the concentrated piglet feed provided by the present invention can promote the growth and development of piglets.

[0079] Example 6

[0080] In order to prevent the impact of diseases while promoting the growth of piglets, Bupleurum volatile oil is added to the concentrated piglet feed to inhibit a variety of bacteria and viruses. This can avoid the decline in digestive ability of piglets due to diseases and ensure the normal growth of piglets.

[0081] Bupleurum volatile oil contains a variety of compounds such as myrtenol, which can promote the intestinal development of piglets, thereby helping to improve the appetite of piglets. Myrtenol contains hydroxyl functional groups, which can react with phosphoric acid in the composite acidifier and phosphoric acid generated after calcium dihydrogen phosphate is dissolved in water to form phosphate esters. The reaction principle is as follows:

[0082] R-OH+H3PO4→R-OP(O)OH+H2O

[0083] In the formula, R-OH is myrtenol, H3PO4 is phosphoric acid, R-OP(O)OH is a phosphate derivative, and H2O is water. The hydroxyl functional group (-OH) of myrtenol can react with phosphoric acid to produce phosphate ester. Phosphate ester can help digest and decompose fat, making it easier to absorb, thereby improving the digestion and absorption capacity of piglets.

[0084] In order to determine that the composition of bupleurum volatile oil and the 1-3% mass proportion of bupleurum volatile oil are one of the important factors that the concentrated piglet feed provided by the present invention can promote the growth of piglets, this embodiment, on the basis of the above embodiment 2, only changes the mass proportion of bupleurum volatile oil, and sets the mass proportion of bupleurum volatile oil to 0%, 0.5%, 1.7%, 1.9%, 2.2% or 3.5%, and then prepares a concentrated piglet feed, and uses it for feeding piglets, and detects according to the average daily weight gain detection method of piglets provided in the above embodiment. The test results are as follows: Figure 3 shown.

[0085] according to Figure 3It can be seen that when the mass proportion of Bupleurum volatile oil is 0%, that is, when the concentrated piglet feed does not contain Bupleurum volatile oil, the average daily weight gain of the piglets is significantly reduced, indicating that Bupleurum volatile oil is one of the important components in the concentrated piglet feed that promotes the growth and development of piglets;

[0086] In addition, when the mass proportion of Bupleurum volatile oil in the prepared piglet concentrated feed is 0.5% or 3.5%, that is, the mass proportion of Bupleurum volatile oil is not 1-3%, the average daily weight gain of piglets is significantly lower than the average daily weight gain of piglets when the mass proportion of Bupleurum volatile oil in the prepared piglet concentrated feed is 1.7%, 1.9% or 2.2%.

[0087] It can be explained that the volatile oil components of Bupleurum Root and the 1-3% mass proportion of Bupleurum Root volatile oil are one of the important factors that the concentrated piglet feed provided by the present invention can promote the growth and development of piglets.

[0088] Example 7

[0089] The concentrated feed for piglets is prepared according to the formula provided in the above embodiment and the determined optimal ratio, and then the average daily weight gain of piglets is detected according to the detection method provided in the above embodiment;

[0090] The test shows that under the working conditions of this embodiment, after eating the concentrated piglet feed, the piglets have a higher average daily weight gain, which indicates that the concentrated piglet feed provided by the present invention has a good growth-promoting effect.

[0091] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
