Abstract

The invention relates to the field of feed additives, and the feed additive is prepared by taking methylation modified tea polyphenol as a core material in a breakthrough manner, cooperating with a self-emulsifying micro-capsule technology for treatment, using a specific wall material combination and proportion and adopting a specific process and parameters. The invention provides the enteric tea polyphenol feed additive which is high in biological activity, free of biological toxicity and good in stability and the preparation method of the enteric tea polyphenol feed additive. The obtained product is extremely easy to enter lymphatic circulation through intestinal mucosa absorption and then enters blood circulation, so that the biological efficiency of the product is efficiently exerted, the product has strong advantages in the aspects of stability, intestinal absorption efficiency, reduction of the liver-intestine first-pass effect, usage amount and the like, and the feed additive is far superior to a common feed additive for improving the meat quality of livestock and poultry at present. Test results show that the enteric-coated tea polyphenol group can significantly improve the muscle ash content, SOD and GSH-Px vitalities and the redness a* value (P is smaller than 0.05) and significantly reduce the water loss rate (P is smaller than 0.05) of pectoralis muscles and leg muscles of Manggang geese, and the addition amount is only 300 mg of enteric-coated tea polyphenol per kg of basic feed.

Description

technical field [0001] The invention relates to the technical field of feed additives, and provides an enteric-coated tea polyphenol feed additive for improving the quality of livestock and poultry meat, a preparation method and application thereof. Background technique [0002] With the development of my country's economy and the improvement of living standards, new requirements are constantly being put forward for the quantity and quality of livestock and poultry products. In particular, the consumption demands of today's market are obviously diversified, not only to eat well, but also to eat healthily. Green ecological food is increasingly favored. As far as my country's mainstream livestock and poultry products such as pork, poultry meat, and poultry eggs are concerned, consumers pay more attention to nutrition and health, which also poses new development directions and challenges for livestock and poultry breeding and production. Taking pork as an example, pork must not ...
