摘　　要：在现代化畜禽生产中,热应激已成为制约肉鸡生长、代谢、肉品质及生理功能的重要因素之一,给养殖业带来了严重的经济损失。热应激蛋白(heat shock protein,HSPs)是动物在不良因素作用下所产生的一组特异性蛋白质,而HSP70是其家族成员中最保守、最重要的蛋白之一;它具有分子伴侣、热耐性,抗过氧化损伤等特性,能够使机体迅速适应环境变化,在热应激保护中发挥了重要的作用。作者主要阐述了热应激对肉鸡的影响和HSP70的生物学特点及其抗热应激的作用机理,以期为从药物方面探讨HSP70的抗应激功能提供理论依据。In modern livestock production,heat stress has become the one of the important factors,restricted the broilers growth,metabolism,meat quality and physiological functions,for breeding brought serious economic damage.Heat stress proteins（HSPs） is a group of specific proteins that produce under adverse factors,and HSP70 is one of the most conservative and the most important members of the family.It has may perform a series of biological function,such as molecular chaperone,enhancing tolerance and antioxidant injury and so on.It can make the body quickly adapt to the environment changes and in the heat stress it play an important roal.This paper introduced the effect of heat stress on broilers,the biological characteristics and the heat stress mechanism of HSP70,in order to provide theory basis functions for exploring anti-stress mechanism of HSP70 from medicines level.
