At the same time, the excess enzymes after the enzymolysis are inactivated by heating to prevent excessive decomposition of the product, thereby ensuring the stability of the enzymolysis product and improving the nutritional supply and digestion and absorption effect of the feed additive on the animal. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Figure 1 The present invention is a flow chart of the preparation method of a highly effective feed additive based on optimized citrus residue components. DETAILED DESCRIPTION

[0031] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings 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.

[0032] Please refer to the attached Figure 1 The embodiment of the present invention provides a high-efficiency feed additive based on the optimization of the components of citrus residue and a preparation method thereof, comprising the following parts by weight: 30-60 parts of citrus residue, 10-20 parts of amino acids, 5-15 parts of vitamin premix, 3-8 parts of mineral premix, 5-20 parts of probiotics, 0.6-4 parts of cellulase, 0.45-3 parts of pectinase and 0.75-4 parts of amylase.

[0033] Specifically, citrus dregs are rich in cellulose, polyphenols, flavonoids and other ingredients, and play an important role as a basic raw material in feed additives. Its polyphenols and flavonoids have antioxidant effects, which can help animals remove free radicals in the body, enhance the body's antioxidant capacity, improve immunity, and reduce the occurrence of diseases. In addition, citrus dregs have a wide range of sources and relatively low costs. As a feed additive ingredient, it reduces feed costs to a certain extent and improves resource utilization.

[0034] Amino acids are the basic units of protein. Their addition can balance the amino acid composition in feed, meet the animal's needs for essential amino acids, and improve protein utilization, thereby significantly promoting animal growth, increasing feed conversion rate, and improving animal production performance.

[0035] Vitamins are trace organic substances necessary for animals to maintain normal physiological functions. They play an irreplaceable role in animal metabolism, growth and development, reproduction and immunity. Adding vitamin premixes can prevent animal vitamin deficiency, ensure the healthy growth of animals, and improve reproductive performance and disease resistance.

[0036] Minerals are important components in the animal body and play a key role in the animal's physiological functions such as bone development, nerve conduction, muscle contraction, and blood coagulation. Adding mineral premixes can meet the animal's needs for various minerals, prevent diseases caused by mineral deficiency or excess, and improve animal production performance and product quality.

[0037] Probiotics help regulate the balance of animal intestinal microecology and have many benefits for animal health. After entering the animal intestine, probiotics can inhibit the growth and reproduction of harmful bacteria through competitive exclusion. At the same time, probiotics can produce beneficial metabolites such as organic acids and bacteriocins, lower the intestinal pH value, create an environment that is not conducive to the survival of harmful bacteria, promote the growth of beneficial bacteria, and stimulate the animal intestinal immune system, enhance the activity of immune cells, improve the animal's immunity and disease resistance, and improve the efficiency of feed digestion and absorption.

[0038] Cellulase can decompose cellulose in citrus residue and other feed raw materials into small molecular sugars such as glucose that can be absorbed and utilized by animals, significantly improving the nutritional value of feed, increasing the contact and absorption of nutrients such as protein and fat by animals, and at the same time, reducing the cellulose content in feed, reducing its mechanical stimulation to the animal intestine, and improving the palatability and digestibility of feed. Especially for feeds mainly based on plant raw materials, adding cellulase can effectively improve feed utilization;

[0039] Pectinase mainly acts on the pectin component in the citrus residue, reducing the viscosity of feed additives, thereby improving the fluidity and dispersibility of feed additives. After pectinase decomposes pectin, it can release nutrients such as protein and starch in cells, increase the availability of these nutrients, and cooperate with amylase to better play its role, further improve the nutritional value and digestion and absorption utilization rate of feed, and promote the healthy growth of animals.

[0040] Amylase can break down starch in feed into small molecule sugars such as maltose and glucose, providing animals with an easily absorbed energy source. In the digestive process of animals, starch is an important energy substance, but the amylase secreted by animals themselves is limited. Adding amylase can make up for this deficiency, improve the digestion efficiency of starch, improve the energy utilization rate of feed, meet the energy needs of animal growth and activity, and promote the growth and development of animals and the improvement of production performance.

[0041] Amino acids include methionine, lysine and threonine, and the amino acid purity is higher than 98.5%.

[0042] Specifically, methionine, lysine and threonine are key amino acid components in feed additives, and their purity is higher than 98.5%. They each play a unique and important role. Methionine, as a sulfur-containing essential amino acid, not only participates in protein synthesis in animals, but is also of great significance to feather growth and repair. It can also help liver fat metabolism and maintain liver health. Lysine can promote muscle protein synthesis and increase lean meat rate, while it can also enhance animal immunity. Threonine plays a key role in immunoglobulin synthesis and maintaining the integrity of intestinal mucosa. It is effective in enhancing animal immunity, promoting intestinal health and improving feed digestion and absorption efficiency, thereby optimizing feed amino acid balance, significantly improving feed protein utilization, promoting animal growth and development, enhancing animal immunity and disease resistance, and comprehensively improving animal production performance.

[0043] The vitamin premix includes vitamin A, vitamin B and vitamin D, and the vitamin premix is ​​prepared by mixing corn starch. The mineral premix includes calcium carbonate, calcium dihydrogen phosphate and ferrous sulfate, and the mineral premix is ​​prepared by mixing with stone powder.

[0044] Specifically, vitamin A in the vitamin premix can maintain normal visual function and protect tissues such as the skin and mucous membranes. Vitamin B participates in a variety of metabolic processes in animals to ensure the normal functioning of animal physiological activities. Vitamin D helps absorb and utilize calcium and phosphorus, and is essential for the development of bones and teeth and maintaining their strength. The premix is ​​made by mixing corn starch, which helps to evenly disperse the vitamins.

[0045] In the mineral premix, calcium carbonate provides animals with a rich source of calcium and is a key component in the formation of bones and eggshells. Calcium dihydrogen phosphate supplements both calcium and phosphorus, effectively promoting bone development and maintaining the body's phosphorus balance. Ferrous sulfate is an important raw material for synthesizing hemoglobin and can prevent iron deficiency anemia in animals. At the same time, the premix is ​​mixed with stone powder to better achieve a uniform distribution of various minerals, thereby fully meeting the vitamin and mineral needs of animals for growth, development, reproduction and health maintenance.

[0046] Probiotics include Bacillus subtilis, Lactobacillus acidophilus and Bifidobacterium, and the effective live bacterial count of probiotics is not less than 10 billion / g.

[0047] Specifically, Bacillus subtilis can produce a variety of digestive enzymes to help animals digest and absorb nutrients in feed, and can also secrete antibacterial substances to inhibit harmful bacteria. Lactobacillus acidophilus can ferment in the intestines to produce a large amount of lactic acid, lower the pH value of the intestine, inhibit the growth of harmful bacteria, and at the same time enhance the intestinal barrier function to prevent the invasion of pathogens. Bifidobacterium, as the dominant beneficial bacteria in the intestine, can not only regulate the balance of intestinal flora and improve the intestinal microecological environment, but also stimulate the animal immune system and enhance the body's immunity.

[0048] The preparation method of a high-efficiency feed additive based on the optimization of oil palm residue components comprises the following steps:

[0049] S1. Raw material pretreatment: collecting fresh citrus residues, removing impurities therein, drying the citrus residues using low-temperature drying technology, and then crushing and sieving the citrus residues through a pulverizer to obtain citrus residue powder;

[0050] S2, enzymatic premixing: putting the pretreated citrus residue powder into a reactor, adding water, and mixing with cellulase and pectinase for enzymatic hydrolysis;

[0051] S3, main mixing: amino acids, vitamin premix, mineral premix, probiotics, amylase and enzymatically hydrolyzed citrus residues are placed in a mixer and mixed;

[0052] S4, extrusion granulation: the mixed material is subjected to conditioning treatment and then transported to an extruder for granulation;

[0053] S5. Material screening: The feed additive particles after extrusion granulation are screened through a vibrating screen, and the oversized particles are returned to the extruder for re-granulation;

[0054] S6. Packaging and storage: The qualified feed additive granules after screening are packaged and stored by a packaging machine.

[0055] Specifically, in S1, the impurities are removed after the fresh citrus residue is collected, which can prevent the impurities from affecting the quality of feed additives and animal health. The low-temperature drying technology can reduce the moisture content of the citrus residue, inhibit the growth and reproduction of microorganisms, and extend the shelf life while minimizing the loss of nutrients in the citrus residue. The citrus residue powder is obtained by crushing and sieving with a pulverizer, which increases the specific surface area of ​​the citrus residue, facilitates subsequent uniform mixing with other ingredients, improves the overall quality and stability of the feed additive, and is more convenient for animals to eat and digest.

[0056] In S2, the pretreated citrus residue powder is mixed with water, cellulase and pectinase for enzymatic hydrolysis, which can further improve the nutritional value and digestibility of the citrus residue, and release more nutrients in the cells. At the same time, the premixing process allows the enzymatic hydrolysis products of the citrus residue to initially contact with the subsequent added ingredients, laying the foundation for a more uniform fusion of the subsequent main mixing, which helps to improve the nutritional supply and digestion and absorption effect of feed additives for animals;

[0057] In S3, amino acids, vitamin premixes, mineral premixes, probiotics, amylase and the hydrolyzed citrus residues are put into a mixer and mixed thoroughly to ensure that the feed additives are nutritionally comprehensive and evenly distributed, so that the feed additives are uniform at the microscopic level, and the nutrients ingested by the animals when feeding are stable and balanced, thereby improving the quality and use effect of the feed additives;

[0058] The materials after the main mixing in S4 are first subjected to conditioning treatment. By adjusting the temperature and humidity, the materials are made into a state suitable for granulation, starch gelatinization and protein denaturation, which not only improves the physical properties of the materials and facilitates molding, but also improves the palatability and digestibility of the feed. The materials are then transported to the extruder for granulation, and the mixed materials are made into particles of a specific shape and size, which is convenient for animals to eat and reduces feed waste. At the same time, the pellet feed is easier to store and transport, has better stability during storage, and is less likely to separate components;

[0059] In S5, a vibrating screen is used to screen the feed additive particles after extrusion granulation, and particles that meet the particle size requirements can be screened out. Oversized particles are returned to the extruder for re-granulation to ensure that the feed additive particles are uniform in size, which not only improves the appearance quality of the product, but also ensures the consistency of animal feeding, avoids feeding difficulties or unbalanced nutrition intake for some animals due to differences in particle size, and improves the market competitiveness of the product;

[0060] The qualified feed additive particles that have been screened in S6 are packaged by a packaging machine, which provides a physical protection barrier for the product to prevent it from being damp, oxidized, and contaminated during storage and transportation, thereby maintaining the nutritional content and quality of the feed additive.

[0061] In S1, the citrus residue is dried at a temperature of 50-60° C. by low-temperature drying to reduce the moisture content to below 10%, and then the citrus residue is crushed by a pulverizer so that the citrus residue can pass through a 40-60 mesh sieve to obtain citrus residue powder.

[0062] Specifically, the temperature range of 50-60°C can not only effectively remove moisture, but also avoid the massive loss of heat-sensitive nutrients such as vitamins and polyphenols in the citrus residue due to high temperature. At the same time, reducing the moisture content can inhibit the growth of microorganisms and extend the shelf life of the citrus residue. Subsequently, the citrus residue is crushed by a grinder and allowed to pass through a 40-60 mesh sieve to increase the specific surface area of ​​the citrus residue. In the subsequent steps, whether it is in contact with the enzymatic solution for enzymatic reaction or mixed with other ingredients, it can act more fully, improve the reaction efficiency and mixing uniformity, lay a solid foundation for the production of high-quality feed additives, and ultimately improve the digestion and absorption of feed additives by animals.

[0063] S2 specifically includes the following steps:

[0064] S101, dissolving cellulase and pectinase respectively in water to prepare enzymatic solution;

[0065] S102, enzymolyzing the enzymatic solution and the pretreated citrus residue powder in a reaction kettle, and stirring at 30-50 rpm;

[0066] S103, after the enzymatic hydrolysis is completed, the reaction kettle is heated to 90-100° C. for 5-10 minutes to completely inactivate the enzyme activity.

[0067] Specifically, in the enzymatic premixing stage, first, cellulase and pectinase are dissolved in water to prepare enzymatic solution, so that the enzymes can be fully dispersed, creating conditions for the subsequent efficient enzymatic hydrolysis of citrus residues. Then, the enzymatic solution and the pretreated citrus residue powder are stirred at a speed of 30-50 rpm in the reactor for enzymatic hydrolysis, and excessive stirring is avoided to damage the reaction system, so that cellulase and pectinase can efficiently decompose cellulose and pectin in the citrus residues, release more nutrients, and improve the nutritional value of the feed. After the enzymatic hydrolysis is completed, heating can completely inactivate the enzyme activity, accurately control the end point of the enzymatic hydrolysis reaction, prevent the enzyme from continuing to act in the subsequent processing, resulting in excessive decomposition of the product or unnecessary reaction, and ensure the stability of the enzymatic hydrolysis product.

[0068] S3 specifically includes the following steps:

[0069] S201, putting the citrus residue material into a stirring mixer at a speed of 30-50 rpm to preliminarily disperse the citrus residue material in the mixer;

[0070] S202, then add the mineral premix and the mineral premix into the mixer, increase the speed to 80-120 rpm, and continue stirring for 15-25 minutes;

[0071] S203. Finally, the amino acids, probiotics and amylase are put into a mixer. The temperature in the mixer is controlled at 25° C.-40° C. and the stirring speed is controlled at 50-80 rpm.

[0072] Specifically, the citrus residue material is first put into a stirring mixer for preliminary dispersion to build a uniform foundation for the subsequent integration of ingredients and avoid material concentration affecting the mixing effect. Subsequently, the mineral premix is ​​added and the rotation speed is increased to allow the minerals to fully blend with the citrus residue. The strong stirring force is used to evenly distribute the minerals to ensure that the animals take in a balanced mineral nutrition. Finally, amino acids, probiotics and amylase are added at an appropriate temperature. The appropriate temperature prevents the inactivation of probiotics and amylase and the denaturation of amino acids. This rotation speed ensures that amino acids, probiotics and other materials are evenly mixed, thereby comprehensively improving the quality of feed additives and providing a stable and high-quality source of nutrition for the healthy growth of animals.

[0073] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
