Effects of Heat Stress on Rumen Function and Potential Heat Tolerance Markers in Ruminants
Heat stress is one of the important factors affecting animal health and production,and rumen function is closely related to nutrient absorption,body health and production performance of ruminants.Heat stress can easily cause changes in rumen microbial structure,rumen epithelial structure and barrier function,which in turn affects rumen function in ruminants.Current studies have shown that some specific rumen microorganisms,metabolites,and rumen epithelial protein expression in the rumen can be used as potential markers to evaluate the magnitude of heat stress in ruminants.By screening the potential heat tolerance markers of rumen and accurately judging the degree of heat stress in the rumen,it is helpful to better understand the mechanism of heat resistance in ruminants,and is also of great significance for the study of rumen microbial structure,rumen metabolism and rumen function.Therefore,the authors mainly review the effects of heat stress on rumen microbial structure,rumen function and potential heat tolerance markers of rumen,so as to provide theoretical basis and guidance for practical production and application under heat stress conditions.
