Tea polyphenol cow feed

Abstract

The invention belongs to the technical field of animal husbandry and discloses a tea polyphenol milk cow feed, which comprises feed and a tea polyphenol additive, and the feed and the tea polyphenol additive are stirred and mixed. The invention provides a tea polyphenol dairy cow feed, wherein the tea polyphenol additive can activate the intracellular Nrf2-ARE pathway, enhance the expression of antioxidant proteins, improve the antioxidant capacity of cells, reduce cell damage and mutation, and significantly reduce the risk of oxidative stress. It is a new and effective method to treat oxidative stress-related diseases in dairy cows by reducing the incidence of stress-related metabolic diseases in dairy cows and greatly improving the production performance and health status of dairy cows.

Description

technical field [0001] The invention specifically relates to a tea polyphenol dairy cattle feed, which belongs to the technical field of animal husbandry. Background technique [0002] During the peripartum period, dairy cows exhibited antioxidant dysfunction and immune dysfunction after undergoing drastic physiological changes from mammary gland atrophy to rapid development, from rapid fetal growth to parturition, from dry milk to milk synthesis and secretion, resulting in Low production performance, while increasing the incidence of infectious diseases and metabolic diseases such as mastitis, retained placenta, displaced abomasum, and endometritis. [0003] The application of tea polyphenols at home and abroad is mainly concentrated on humans and mice. There are relatively few reports on goats, chickens, pigs, piglets, and meat ducks. The research reports on dairy cows can only be seen in Wang Zhenyun's (2011) master thesis "Tea Polyphenols Protective Effect on Oxidative ...

AI Technical Summary

Problems solved by technology

[0003] The application of tea polyphenols at home and abroad is mainly concentrated on humans and mice. There are relatively few reports on goats, chickens, pigs, piglets, and meat ducks. The research reports on dairy cows can only be seen in Wang Zhenyun's (2011) master thesis "Tea Polyphenols Protective Effect on Oxidative Stress Damage of Dairy Cow Mammary Epithelial Cells", but this study only determined that a certain concentration of tea polyphenols can alleviate the damage of dairy cow mammary epithelial cells caused by oxidative stress and improve the antioxidant capacity; the specific mechanism It is only clear that tea polyphenols can reduce the caspase-3 activity of mammary epithelial cells damaged by oxidative stress, and can reduce the cell apoptosis rate. Therefore, we propose a tea polyphenol dairy cow feed
