摘　　要：围产期是奶牛生产周期的关键时期,面临生理和代谢挑战,包括免疫力减弱和能量负平衡。近年来研究表明,通过补饲过瘤胃蛋氨酸可改善围产期奶牛的健康状况和生产性能。本文阐述奶牛围产期、过瘤胃蛋氨酸的重要性、补饲过瘤胃蛋氨酸对围产期奶牛健康和生产性能的影响,以期为蛋氨酸在奶牛围产期营养调控研究和应用提供理论基础。The transition period is a critical period in the production cycle of dairy cows,which face physiological and metabolic challenges,including weakened immunity and negative energy balance.In recent years,studies have shown that supplementing rumen-protected methionine can improve the health and production performance of dairy cows during the transition period.This paper explained the importance of the transition period of dairy cows and rumen-protected methionine,and the impact of supplementing rumen-protected methionine on the health and production performance of dairy cows during the transition period,in order to provide a theoretical basis for the research and application of methionine in the nutritional regulation of dairy cows during the transition period.
