Abstract：The lactational performance of dairy cows is closely related to mammary gland health and is susceptible to various environmental factors and nutritional factors.Among these,oxidative stress is a key factor affecting both lactational performance and mammary health in dairy cows.Oxidative stress can destroy the normal physiological function of breast tissue,induce the apoptosis of mammary epithelial cells,and lead to the decrease of milk yield and milk quality,causing serious economic losses to the breeding industry.Therefore,this review systematically summarized the main pathways through which factors such as the physiological condition,feeding environment,and dietary factor of dairy cows induced oxidative stress.It sorted out the impacts of oxidative stress on lactational performance and the structure and function of mammary tissue,as well as their action mechanisms,with a specific focus on processes including mammary epithelial cell apoptosis and inflammatory responses,exploring the role of related signaling pathways in mediating the decline of lactational function.At the same time,the research progress of adding vitamins,minerals,plant extracts and other nutrients to the diet to alleviate the oxidative stress injury of dairy cows was summarized,in order to provide a theoretical reference for improving the lactation performance of dairy cows and reducing oxidative stress injury.
