热应激对畜禽肠道微生物的影响研究进展

Research Progress of Heat Stress on the Intestinal Microbiota of Livestock and Poultry

热应激导致畜禽肠道健康损伤,降低畜禽生产性能,给畜牧业带来巨大经济损失。近年来,越来越多的学者发现热应激导致的畜禽肠道健康损伤与肠道微生物的变化息息相关,但是由于研究手段、采样部位、物种等的不同,造成现有研究结果不尽一致。本文以畜禽肠道微生物研究手段的发展为出发点,主要综述热应激对畜禽肠道微生物组成及功能的影响,并指出现有研究的不足,为进一步开展热应激损伤畜禽肠道健康的机制研究提供参考。

Heat stress may harm intestinal health,reduce performance,and bring huge economic losses to the livestock and poultry industry.In recent years,an increasing number of studies have discovered that heat stressinduced intestinal health damage is directly tied to the changes in intestinal microorganisms.However,current study results are not always inconsistent due to differences in research methodology,sample sites,and experimental species.Based on the evolution of research methods of intestinal microbiota in livestock and poultry,this paper primarily reviews the effects of heat stress on the compositions and functions of intestinal microbiota,identifies gaps in existing studies,and provides references for further research on the mechanism of heat stress injury to intestinal health in livestock and poultry.
