摘　　要：泌乳牛的健康和生产性能对畜牧业可持续发展至关重要。瘤胃保护蛋氨酸(RPM)作为一种重要饲料添加剂,在泌乳牛中应用广泛。补饲RPM可显著改善泌乳牛的生产性能、健康状态、饲料利用效率、繁殖性能等,但其效果受饲料配方、饲养管理水平和环境条件、个体差异等多种因素影响。本文综述RPM在泌乳牛营养调控中的作用及其影响因素,为其研究、应用提供理论基础和技术参考。The health and performanceof lactating cows are crucial for the sustainable development of the livestockindustry.Rumen protected methionine(RPM),as an important nutritional supplement,has been widely used in lactating cows.RPM can significantly improve the performance,health status,feed efficiencyand reproductive performanceof lactating cows.However,its effectiveness is influenced by various factors such as feed formulation,feeding management,environmental conditionsand individual differences.This paper reviewed the role and influencing factors of RPM in nutrient regulation of lactating cows to provide theoretical basis and technical references forits research and application.
