Abstract
The invention discloses a feed additive for improving the quality of poultry eggs and a preparation method and application thereof. The feed additive is added into the laying fowl feed, can adjust the immune function of the laying fowl, enhance the disease resistance, reduce the drug residue and bring great social benefit; meanwhile, the quality of the eggs can be obviously improved, the cholesterol content in the eggs can be reduced, the selenium-rich and zinc-rich eggs with low cholesterol can be produced, and the economic benefit of egg and poultry breeding can be improved.
Description
Technical Field
The invention relates to an animal feed, in particular to a feed additive for regulating the immune function of egg-laying poultry, enhancing the disease resistance, improving the quality of egg products, reducing the cholesterol content in eggs and producing low-cholesterol selenium-rich and zinc-rich eggs, and specifically relates to a feed additive for improving the quality of eggs by combining mulberry leaf powder, green tea powder, tea polyphenol, nano selenium and zinc methionine, belonging to the fields of feed industry and livestock breeding industry.
Background
The eggs are one of the important sources of high-quality eggs for human beings, are rich in essential amino acids of the human bodies, such as methionine, lysine and the like, and simultaneously contain a large amount of trace elements required by the human bodies, such as calcium, phosphorus, iron, zinc and the like, and are ideal natural foods. However, under modern feeding conditions, egg-laying poultry are in a sub-health state, the immunity level of the organism is low, diseases of the reproductive system, intestinal tract and respiratory tract are frequent, and the benefits of breeding enterprises are seriously damaged. In order to improve economic benefit, egg poultry breeding practitioners use a large amount of chemical drugs such as antibacterial and anti-inflammatory drugs, coccidian-resistant drugs and the like in the feed, so that the quality of eggs is seriously influenced, and in addition, the problems of drug residues, drug resistance of pathogenic bacteria and the like are caused, thereby causing great harm to human health. Therefore, the search for effective substitutes of feed antibiotics and the production of safe and high-quality animal products without public hazard, residue and pollution become the focus of attention of people. Therefore, the research and the wide application of the safe and environment-friendly feed have important significance for promoting the sustainable development of the breeding industry in China.
In recent years, researches show that the health condition of animal bodies can be improved and the quality of eggs can be improved through vegetality and nutrition. The mulberry leaves contain a large number of functional components, such as flavone and flavone glycosides (quercetin and the like), alkaloid (DNJ and the like), polysaccharide and the like, and have the functions of resisting stress, resisting oxidation, enhancing the immunity of the organism, reducing serum cholesterol, regulating adrenal gland function, reducing blood fat, reducing blood sugar and the like besides the traditional medicinal value. Researches show that the quality of eggs can be improved, the egg white Hafu unit can be improved, the color of egg yolks can be deepened, the mouthfeel of the eggs can be improved, and the content of cholesterol in the egg yolks can be reduced by adding 5% -10% of mulberry leaf powder into daily ration of laying hens. The green tea not only has the pharmacological effects of refreshing and clearing away heart-fire, clearing away summer-heat, promoting digestion and eliminating phlegm, detoxifying and sobering up, promoting the production of body fluid and quenching thirst, but also has certain pharmacological effects on radiation diseases, cardiovascular and cerebrovascular diseases and the like, and the main active components of the green tea are tea polyphenol, catechin, caffeine, theanine and the like. The tea polyphenol in the green tea has excellent effects of resisting oxidation and cancer, reducing blood fat, improving immunity and the like, and can improve the production performance of livestock and poultry, replace an antioxidant, improve the quality of livestock and poultry products and enhance the immunity of the livestock and poultry. The addition of 1-3% of green tea powder in daily ration of laying hens can effectively reduce the cholesterol content in egg yolk, and has different degrees of influence on the production performance. However, the mulberry leaves and the green tea have high crude fiber content and low effective energy value, and need to be added into the feed in a large amount (more than 5% of mulberry leaves and more than 1% of green tea) to show the effect, but the laying fowl feed has limited formulation space (the laying fowl feed needs high effective energy value), the green tea is expensive, and the addition cost in the feed is high, so the application of the mulberry leaves and the green tea in the commercial laying hen feed is limited.
The trace elements are accessory factors of a plurality of hormones and enzymes in an animal body and have important effects on the metabolism of the body. Selenium and zinc are essential trace elements for human body and animals, and have effects of promoting growth, improving reproductive performance, resisting oxidation, enhancing immunity, and resisting stress. The enrichment of selenium can not only improve the health condition of livestock and poultry, but also improve the value of livestock and poultry products. The nano selenium is a high-quality organic selenium source, is safe and low in toxicity, has high biological activity, and has better absorption rate and deposition amount in organisms than other forms of organic selenium. So far, there is no report on the use of the combination of mulberry leaves, green tea and tea polyphenols, nano-selenium and zinc methionine as a feed additive to improve the quality of poultry eggs.
