Both cold and heat stress can negatively affect the daily gain and feed conversion rate of cattle,which could reduce the production efficiency of the beef cattle industry.This article provides a comprehensive overview of the mechanisms underlying the physiological and biochemical responses of cattle from different regions under cold and heat stress.Additionally,the molecular mechanisms and regulatory genes associated with cold and heat stress were investigated,and practical approaches to mitigate these stressors,such as altering feeding habits and molecular breeding grounded in genome-wide association studies(GWAS),were deliberated and suggested within the beef cattle sector.The review provided the theoretical basis for a better understanding of the mechanisms of cold and heat stress in the beef cattle industry,which could be used in breeding programs to improve production efficiency under cold and heat stress in China.
