Abstract: Cells,tissues and metabolism will be changed when the temperatures above the thermoneutral zone.Recovery system of organism in heat-stress was activated,then the cows begin to store heat, and increase evaporative heatloss (EVHL).If the stress persists, endocrine system will make some deals, accelerate the cows to adapt these changes.This review illustrated during the occur of heat stress on cows, the changes of heat stress protein, incretion and energy metabolize on heat-stressed cows and the acclimation of cows on heat-stress.

Key words: heat stress; energy metabolize; endocrine accommodate; heat stress protein
