摘要
围产期奶牛经历妊娠、分娩、泌乳以及高精料饲喂等一系列代谢应激及外部环境的变化,极易诱发奶牛机体产生氧化应激,进而导致抗氧化功能下降及免疫功能失调,诱发奶牛产生代谢病和炎性疾病。因此,缓解奶牛机体的氧化应激是实现奶牛高生产力的有效方式。茶多酚作为一种绿色无公害的天然抗氧化剂,将其合理地添加到奶牛的日粮中,能够提高奶牛机体的抗氧化性,有效缓解因氧化应激出现的炎性反应、免疫功能失调等问题。文章围绕由氧化应激引起的围产期奶牛代谢病和炎性疾病的发病机制以及茶多酚的调控作用进行综述,旨在为后续在奶牛生产中应用茶多酚提供思路。
A series of metabolic stress and changes in external environment such as pregnancy,delivery,lactation and high concentrate feeding,can easily induce oxidative stress in the body of periparturient cows,and then lead to the decline of antioxidant function and immune dysfunction,which can induce metabolic diseases and inflammatory diseases in cows.Therefore,relieving oxidative stress is an effective way to achieve high productivity of dairy cows.As a kind of green and pollution-free natural antioxidant,tea polyphenols can be reasonably added to the diet of dairy cows to improve the antioxidant activity of dairy cows,and effectively alleviate the inflammatory reaction and immune dysfunction caused by oxidative stress.The review focuses on the pathogenesis of metabolic and inflammatory diseases caused by oxidative stress in perinatal dairy cows and the regulatory effect of tea polyphenols,aiming to provide ideas for the subsequent application of tea polyphenols in dairy production.
