摘　　要：受多种因素影响,奶牛围产期处于能量和其他营养物质的负平衡状态,多发营养代谢病。研究表明,蛋氨酸可调控奶牛围产期能量和脂质代谢,改善肝脏功能,并可增强机体抗氧化和免疫功能。本文综述了蛋氨酸调控奶牛围产期代谢和机体健康的相关进展,探讨奶牛围产期过瘤胃蛋氨酸的适宜添加量,旨在为蛋氨酸在奶牛围产期的基础研究和应用提供参考。The negative balances of energy and other nutrients usually occur during the transition period because of a series of factors,thereby inducing many metabolic disorders.It is reported that dietary supplementation of rumen-protected methionine can regulate energy and lipid metabolism,improve liver health,and enhance the antioxidant capacity and immune function of transition dairy cows.In this article,the physiological metabolism and body health of transition dairy cows regulated by rumen-protected methionine were reviewed,and the appropriate supplementation doses were discussed as well.Hence,this review could provide references for the fundamental research and application of methionine in transition dairy cows.
