从早期热习服的概念、耐热力的评价指标以及早期热习服的时机出发，总结与分析了早期热习服对肉鸡后期耐热力形成的影响规律，试图探索出早期热习服提高肉鸡后期耐热力的机理。

英文摘要：

The paper sum ups the concept of early age thermal acclimation, estimating indices of heat tolerance and the times for early age thermal acclimation, in order to find out the relation between early age thermal acclimation and the function of anti- adversity, and the mechanism of thermotolerance enhanced by early age thermal acclimation in broiler.
