Heat stress limits the production of dairy cows,which affects embryonic development seriously and reduces reproductive performance significantly.With the increase of global warming and the improvement of large-scale farm-ing,the negative effects of heat stress on the reproductive performance of dairy cows have become more and more prominent.This paper described the effects of heat stress on the embryonic development of dairy cows from the aspects of endocrinology,oocyte maturation,early embryo quality and fetal health,so as to provide references for the improve-ment of the reproductive efficiency of dairy cows.
