奶牛热应激调控措施研究进展

Research Progress on Measures to Relieve Heat Stress in Dairy Cows

随着奶牛养殖业趋向集约化和全球变暖日益加剧,热应激成为制约奶牛生产性能提高的重要因素之一,对奶牛的泌乳性能、机体健康和繁殖性能等造成了严重危害。因此,如何缓解热应激对奶牛生产的影响受到了普遍关注。本文通过整理近年来相关研究,从牛舍、日粮和遗传育种等角度论述了降低奶牛热应激影响的具体措施,以期为奶牛的健康养殖提供参考。

With the intensification of dairy farming and the increasing global warming,heat stress has become one of the important factors restricting the improvement of production performance of dairy cows,causing serious harm to milk performance,body health and reproductive performance of dairy cows.Therefore,how to alleviate the impact of heat stress on dairy cow production has received widespread attention.Based on recent studies,this paper discussed the measures to reduce heat stress of dairy cows from the perspectives of cattle barn,diet and genetic breeding,so as to provide reference for the healthy breeding of dairy cows.
