Description

Technical Field

[0001] The invention relates to the technical field of feed additives, in particular to a feed additive for improving the production performance of laying hens and the quality of eggs. Background Art

[0002] During the egg-laying chicken farming process, egg-laying chickens become weaker due to frequent production, and the stress period after laying eggs is significantly prolonged. During the stress period, egg-laying chickens are more susceptible to bacterial infection and become sick, resulting in damage to the reproductive system, suspension or cessation of follicle development, a significant decrease in production performance, and a significant deterioration in the quality of eggs produced, which seriously affects the economic benefits of egg-laying chicken farming.

[0003] Traditional antibiotics can solve the above problems, but antibiotic residues can easily cause food safety problems in eggs. In the new era of comprehensive antibiotic ban in feed, the feed industry urgently needs to develop green, safe, and non-toxic feed additives to improve the production performance of laying hens and the quality of eggs.

[0004] Eucommia ulmoides has been used as a traditional Chinese medicine for more than 2,000 years in my country. The planting area of ​​Eucommia ulmoides in my country is as high as 6 million mu, accounting for more than 99% of the world's total Eucommia ulmoides resources, and the annual number of Eucommia ulmoides leaves is even more considerable. As the main raw material for animal feed additives, Eucommia ulmoides leaves can enhance the growth performance of livestock and poultry, improve meat quality, enhance the immunity of livestock and poultry, and enhance the nutritional value of livestock and poultry products. Therefore, using Eucommia ulmoides leaves as feed additives is of great significance to the development of animal husbandry.

[0005] The main components of Eucommia leaves are chlorogenic acid, Eucommia flavonoids, and Eucommia polysaccharides. In addition, it also contains a variety of amino acids, vitamins, minerals, etc., which have the effects of enhancing immunity, anti-inflammatory, antibacterial and antioxidant. The effective ingredients of Eucommia leaves are coated by cell walls. If Eucommia leaves are directly added to feed, the utilization rate of their effective ingredients is low, the efficacy cannot be fully exerted, the therapeutic effect is poor, and the palatability is poor, resulting in low feed intake of livestock and poultry. Therefore, effective processing of Eucommia leaves is the key to fully exerting their efficacy, and it is also the key to the research and development of Eucommia leaf feed additives. Summary of the invention

[0006] The invention provides a feed additive for improving the production performance of laying hens and the quality of eggs. The feed additive is green, safe and has no toxic side effects and is made from eucommia leaves as a main raw material. The enzyme-bacteria synergistic fermentation technology is used to gently break the eucommia leaves to release the effective ingredients therein to the maximum extent, thereby improving the utilization rate of the effective ingredients in the eucommia leaves and giving full play to their medicinal effects.

[0007] The technical solution of the present invention is achieved as follows: a feed additive for improving the production performance of laying hens and the quality of eggs, composed of the following ingredients in parts by weight: 40-60 parts of eucommia leaf powder, 30-45 parts of wheat bran, 8-10 parts of soybean meal, 2-6 parts of compound enzyme preparation, and 0.2-0.5 parts of compound probiotics.

[0008] Furthermore, 55 parts of eucommia leaf powder, 35 parts of wheat bran, 10 parts of soybean meal, 5 parts of compound enzyme preparation, and 0.3 parts of compound probiotics.

[0009] Furthermore, the complex enzyme preparation comprises cellulase and protease, and the weight ratio of cellulase to protease is 1:1.

[0010] Furthermore, the composite probiotics comprises Lactobacillus plantarum and Lactobacillus acidophilus, and the weight ratio of Lactobacillus plantarum to Lactobacillus acidophilus is 1:1.

[0011] Further, cellulase ≥ 500 U / g and protease ≥ 4800 U / g.

[0012] The preparation method of the feed additive comprises the following steps: (1) Collecting fresh leaves of Eucommia ulmoides, drying them in the sun, crushing them, and passing them through a 5 mm sieve to obtain Eucommia ulmoides leaf powder; (2) Weigh eucommia leaf powder, wheat bran, soybean meal, compound enzyme preparation, and compound probiotics according to weight, add them to a fermentation tank, evenly spray 50-80 parts by weight of water, and stir evenly; (3) Anaerobic fermentation at 33℃-37℃ for 5-7 days can produce feed additives.

[0013] The feed additive is added in an amount of 3%-6% wt in laying hen feed.

[0014] Beneficial effects of the present invention: The present invention uses eucommia leaves as the main raw material, and the prepared feed additive is green, safe, and has no toxic side effects. The main components of eucommia leaves are chlorogenic acid, eucommia flavonoids, and eucommia polysaccharides, among which chlorogenic acid has strong anti-inflammatory, antibacterial, and antiviral effects, and can protect laying hens from bacterial and viral infections; eucommia flavonoids promote the development of the reproductive system of laying hens and relieve their reproductive stress; eucommia polysaccharides promote the development level of immune organs, improve the body's immune response ability, and can also maintain the balance of intestinal flora, reduce the occurrence of intestinal diseases, and enhance the physique of laying hens. Therefore, the feed additive prepared with eucommia leaves as the main raw material can play a role in improving the production performance of laying hens and the quality of eggs.

[0015] The present invention uses enzyme-bacteria synergistic fermentation technology to gently break the wall of Eucommia ulmoides leaves, release the effective ingredients therein to the maximum extent, and at the same time degrade the macromolecular effective ingredients that cannot be directly absorbed and utilized by the intestines and stomachs of laying hens into small molecules, thereby improving the utilization rate of the effective ingredients of Eucommia ulmoides leaves and giving full play to their efficacy. The feed additive prepared by the present invention is rich in probiotics and their metabolites, such as lactic acid, which can regulate the intestinal flora of laying hens, effectively improve palatability, and increase the feed intake of laying hens.
