Abstract: Heat stress of dairy cows is a non-specific physiological reaction caused by high tempera-ture environment, which can seriously affect the physiological state and embryonic development of dairy cows, and then cause huge economic losses. Therefore, how to improve the development ability of dairy cow embryos under heat stress is of great significance to promote the healthy development of dairy cattle breeding industry. In this paper, the negative effects of heat stress on endocrine, oocytes and embryos of dairy cows, as well as the solution measures such as physical cooling, hormone therapy, addition of IGF1, modification of HSPA1L and PRLR genes by gene editing technology were reviewed, so as to provide some reference for improving the develop-ment ability of dairy cow embryos under heat stress.

Key words: dairy cow, heat stress, oocyte, embryo
