热应激对母牛生殖生理的影响
Effects of Heat Stress on Cow Reproductive Physiology
摘要
Abstract
As the global greenhouse effect intensifies and hot weather persists year after year,heat stress has become one of the significant factors jeopardizing livestock production.Heat stress not only ad-versely affects animal productive performance but also impacts their reproductive physiology,thereby re-ducing reproductive efficiency and causing substantial economic losses in the livestock industry.The repro-ductive process in cattle is complex and involves a prolonged dynamic sequence,during which various sta-ges-such as follicular development,ovulation,fertilization,and pregnancy-are susceptible to external in-fluences.Of particular concern is the pronounced impact of high summer temperatures on conception rate,pregnancy rate,and embryo viability.When animals experience heat stress,they employ several adaptive mechanisms to regulate body temperature,aiming to mitigate damage caused by heat.This review primari-ly discusses the effects of heat stress on bovine reproductive physiology,focusing on follicular develop-ment,granulosa cells,oocytes,and embryonic development.Additionally,it briefly outlines the self-regu-latory strategies employed by cattle to cope with heat stress.The purpose of this paper is to provide guid-ance for alleviating the impact of heat stress on bovine reproductive physiology.关键词
