摘　　要：随着全球气候变暖,热应激对奶牛生产和繁殖性能的影响日显突出,明确热应激如何影响奶牛繁殖并采取应对措施将减少热应激对奶牛养殖业造成的损失。文章就国内外报道的热应激对奶牛发情鉴定、卵子质量、胚胎发育、妊娠率和产科疾病发生率的影响进行了综述,同时还介绍了监测热应激强度的方法和应对热应激影响奶牛繁殖力的措施。With global climate warming, the effect of heat stress on production and reproductive performance of dairy cattle becomes more obvi-ous each day. Therefore, to understand the heat stress how to affect the reproduction of dairy cattle and to take corresponding measures accord- ingly will reduce the loss caused by heat stress to the dairy industry. This paper summarizes the heat stress reported at home and abroad that affects the estrus identification, quality of ovum, embryonic development, It also introduces the methods for monitoring heat stress intensity and the pregnancy rate and the incidence of obstetric diseases of dairy cattle to deal with the effect of heat stress on cow fecundity, providing a reference for the practice of dairy cattle production to avoid and overcome the effect of heat stress.
