Description

Technical Field

[0001] The invention relates to the technical field of pig feed, in particular to a composite pig feed additive and a preparation method thereof. Background Art

[0002] Compound pig feed is an intermediate product made by mixing a variety of feed additives in a certain ratio, which is designed to allow users to prepare complete feed by themselves. This feed usually includes protein feed, energy feed, roughage, green feed, silage, mineral feed and feed additives.

[0003] Compound pig feed can be divided into complete feed, concentrated feed and premix according to category: Complete feed: It consists of four parts: protein feed, energy feed, roughage and additives. It can be directly used to feed the animals and fully meet their nutritional needs1.

[0004] ‌Concentrated feed‌: It is a premix of protein raw materials and additives. Energy feed needs to be added during feeding. It is suitable for large-scale farmers‌1.

[0005] Premix: It is the abbreviation of additive premix feed, which includes a variety of trace components (such as trace mineral elements, vitamins, synthetic amino acids, etc.) and is an important component of complete feed.

[0006] The disadvantages of existing pig feed without additives are as follows: 1. Incomplete nutrition: The main function of feed additives is to improve the nutritional value of feed and increase the utilization rate of feed. If additives are not used, the nutrition of feed may not be complete, resulting in insufficient nutritional intake of pigs, affecting their growth and health.

[0007] 2. Slow growth: The growth agents in the additives can promote the growth of pigs. If these additives are not used, the growth rate of pigs may slow down, resulting in an extension of the breeding cycle and increased breeding costs.

[0008] 3. Health issues: Feed additives also include antioxidants, mildew inhibitors, etc. These additives can extend the shelf life of feed and prevent feed from spoiling. If these additives are not used, the feed will easily spoil, affecting the health of pigs and even causing diseases.

[0009] 4. Environmental issues: Feed additives can also reduce the loss of nutrients during feed storage, thereby reducing environmental pollution. If these additives are not used, feed utilization may decrease, leading to more feed waste and environmental pollution. Summary of the invention

[0010] The purpose of the present invention is to provide a composite pig feed additive and a preparation method to effectively solve the problem that the absence of additives in pig feed will lead to incomplete nutrition, slow growth, health problems and environmental problems, which will affect the growth and health of pigs and increase breeding costs and environmental burdens.

[0011] To achieve the above object, the present invention provides the following technical solutions: A composite pig feed additive and a preparation method thereof, comprising the following steps: S1: Determine the category of additives and prepare raw materials according to different categories: 1. Chinese herbal medicine additives: (1) Paulownia flowers: Dry the Paulownia flowers and grind them into powder; (2) Orange peel powder: dry and crush fresh orange peel; (3) "Fattening Pig Powder": Take 30% Polygonum multiflorum, 25% White Peony Root, 15% Tangerine Peel, 15% Shenqu, 10% Acorus calamus, and 5% Hawthorn, dry them in the sun or in an oven, grind and mix well. The benefits of herbal additives in pig feed mainly include the following aspects: 1. Promote growth and improve meat quality: Chinese herbal additives can promote the growth of pigs and improve the digestion and absorption rate of feed. For example, adding compound additives containing Chinese herbs such as tangerine peel, hawthorn, and Shenqu can increase the apparent digestibility of crude protein and acid detergent fiber in feed, accelerate the metabolism of carbohydrates in the body, and thus improve the absorption of protein and glucose. In addition, Chinese herbal additives can also improve meat quality, reduce carcass backfat thickness, increase eye muscle area, and increase lean meat rate; 2. Improve immunity: Chinese herbal medicine additives can enhance the immune function of pigs and improve their body resistance. For example, feeds containing Chinese herbal medicines such as astragalus and codonopsis can significantly increase the number of white blood cells, red blood cells and lymphocytes in pigs' blood, and increase the content of immune factors such as albumin and globulin in serum, thereby improving the pigs' disease resistance; 3. Disease prevention and treatment: Chinese herbal medicine additives have antibacterial and anti-inflammatory effects, as well as heat-clearing and detoxifying effects, and can prevent and treat a variety of diseases. For example, Chinese medicines such as Scutellaria baicalensis and Coptis chinensis have good preventive and therapeutic effects on bacterial infectious diseases and viral infectious diseases. In addition, alkaloids, flavonoids and other ingredients in Chinese herbal medicines can inhibit the reproduction of pathogenic microorganisms and directly inhibit or kill pathogens; 4. Environmental protection and safety: Chinese herbal medicine additives are natural, environmentally friendly, and have little toxic side effects. Chinese herbal medicines are derived from animals, plants, minerals and their products, and maintain the biological activity of various structural components in their natural state. Unlike antibiotics and chemical synthetic drugs, they have no obvious toxic side effects on the body's physiological functions; 5. Enhance anti-stress ability: Some Chinese herbal medicines can enhance the pigs' defense against various physical, chemical, biological and other harmful stimuli, and restore the disordered functions to normal. For example, astragalus can enhance the body's defense against various harmful stimuli; 2. Plant-based additives: (1) Mugwort: Dry and crush the mugwort; (2) Pine needle powder; (3) fennel; (4) Cypress leaves: Crush cypress leaves and twigs into powder; (5) Motherwort; The benefits of using plant additives in pig feed mainly include the following aspects: 1. Growth-promoting effect: Aromatic substances in plant additives have a fragrant smell, which can correct the taste of feed, improve the palatability of feed, promote the secretion of digestive juice, thereby enhancing digestive function and promoting animal growth; 2. Antimicrobial effect: Plant additives have antiviral, antibacterial and antiparasitic effects. For example, polyphenols and flavonoids can inhibit the growth of influenza viruses and bacteria, and the essential oil in oregano leaves can inhibit pathogenic bacteria such as Salmonella. In addition, some plant extracts such as Coptis chinensis and Dichroa febrifuga have significant effects in preventing and treating coccidiosis. 3. Enhance immunity: Astragalus polysaccharide and Lentinan in plant additives can promote the development of immune organs, improve the body's immunity, and resist viral and bacterial infections; 4. Antioxidant effect: Plant extracts such as thymol, flavonoids and anthocyanins have antioxidant effects and can protect cells from oxidative stress; 5. Improve feed utilization: Plant additives can improve feed utilization and reduce breeding costs through the synergistic effects of their multiple functions, while ensuring animal production performance and product quality; 3. Medicinal additives: (1) Oxytetracycline and bone meal; (2) Rhubarb and gypsum: In summer, add 50g of rhubarb and gypsum to every 100kg of feed; The benefits of medicinal additives in pig feed mainly include the following aspects: 1. Disease prevention and control: Adding appropriate amounts of drug additives to feed can effectively prevent and control common and multiple diseases in pigs. By implementing a drug withdrawal period during the feeding stage, the drug residue in pork can be controlled within a range that is harmless to the human body; 2. Growth promotion: Medicinal additives can promote animal growth and improve feed utilization. For example, adding general additives such as antioxidants to feed, most of these additives are common with additives in the food industry, are food grade, and have no harm to pig growth and pork quality. 1; 3. Improve immunity: By adding medicinal additives to feed, the animal's immune system can be strengthened and its ability to resist diseases can be improved. For example, Chinese herbal additives such as Eucommia ulmoides can enhance the function of adrenal cortex hormones, and have a good effect on sows' fetal health and blood circulation. 4. Improve intestinal health: Using medicinal additives in sow diets can improve intestinal health, enhance sow immunity and reproductive performance. Adding medicinal additives to piglet diets can promote intestinal development, improve intestinal health, reduce diarrhea rates, and increase piglet growth rate and feed conversion rate; 5. Reduce environmental pollution: By using medicinal additives, the health of animals can be improved, the occurrence of diseases can be reduced, thereby reducing the use of antibiotics and other drugs for treating diseases, thereby reducing environmental pollution; 4. Other additives: (1) Baking soda; (2) Garlic; S2: Mixing and stirring: Mix the above raw materials evenly according to the required proportions; S3: Storage and Use: Mixed feed should be stored in a dry, cool and dark environment to maintain its activity.

[0012] Preferably, the powdered particles of Paulownia flowers in the Chinese herbal medicine additive S1 have a diameter of 2 mm, and when used for feeding alone, fattening pigs weighing more than 40 kg are fed 1 tablespoon each time, 2 to 3 times a day.

[0013] Preferably, the percentage of orange peel powder in the Chinese herbal medicine additive S1 added to the dry feed is 5% to 10%.

[0014] Preferably, the percentage of the S1 Chinese herbal medicine additive added to the dry feed for fattened pigs is 1.5%.

[0015] Preferably, the percentage of mugwort in the S1 botanical additive added to the dry feed is 2%, which can increase the daily weight gain of pigs by 10%.

[0016] Preferably, adding 2.5% to 4.5% of pine needle powder in the S1 botanical additive to feed can increase the weight gain of pigs by more than 15%.

[0017] Preferably, the percentage of cypress branches and leaves in the S1 botanical additive added to the dry feed is 3%-5%.

[0018] Preferably, the percentage of Leonurus japonicus in the S1 botanical additive added to the dry feed is 8%.

[0019] Preferably, 10 grams of oxytetracycline and 0.5 kilograms of bone meal in the S1 pharmaceutical additive are mixed into 100 kilograms of feed and fed to pigs. This is suitable for slow-growing piglets and can increase daily weight gain by 5%.

[0020] Preferably, the baking soda in the S1 other additives is fed 10 grams per day.

[0021] In summary, due to the adoption of the above technology, the beneficial effects of the present invention are: 1. Improve intestinal health: Adding feed additives to the diets of sows, piglets and fattening pigs can improve intestinal health, reduce diarrhea rates and promote intestinal development. For example, compound premixes for lactating sows can significantly increase sows’ feed intake and milk production, reduce constipation, and increase piglets’ survival rate and growth rate.

[0022] 2. Improve production performance: Compound additives can significantly increase the daily weight gain and feed conversion rate of pigs. For example, microecological feed additives can significantly increase the daily weight gain of pigs, improve feed conversion rate, and significantly reduce diarrhea rate, showing the same production application effect as antibiotics. In addition, fast compound additives such as "Chuanfu Amino Acids" can significantly increase appetite, promote growth and development, increase daily weight gain, and effectively prevent pig rickets and malnutrition.

[0023] 3. Enhance immunity: Probiotics and other ingredients in feed additives can enhance pig immunity and reduce the occurrence of diseases. For example, compound premixes for lactating sows use multiple vitamins and high-quality electrolytes to alleviate the problems of low feed intake and constipation in summer, while using biological feed raw materials and plant active substances to improve the lactation performance of sows.

[0024] 4. Shorten the fattening period: Using compound premixes can shorten the fattening period and improve economic benefits. For example, Shanghai Bannong Feed's 4% compound premix for fattening pigs is rich in various vitamins, minerals and amino acids, which can make pigs eat healthier and grow faster, shorten the time to market by 15 days, and increase feed conversion rate by 8%.

[0025] 5. Reduce environmental pollution: By improving feed conversion rate and reducing drug use, compound pig feed additives help reduce environmental pollution. For example, the use of microecological feed additives reduces the use of antibiotics, thereby reducing the problem of drug residues and drug resistance. BRIEF DESCRIPTION OF THE DRAWINGS
