摘　　要：夏季高温是影响蛋鸡生产性能的一个重要因素。近年来随着风机+湿帘等降温设施的普及,夏季规模化蛋鸡舍内的温度一般可以控制在30℃以下,因此在实际生产中往往忽略夏季高温的不利影响。本文针对环境高温尤其是循环高温对蛋鸡生产性能的影响进行总结归纳,以期引起生产以及研究人员对于夏季高温的重视,并从饲粮能量和粗蛋白质水平方面总结缓解高温应激影响的营养调控技术,旨在为高温季节蛋鸡合理配制饲粮及饲养管理提供科学依据。Summer heat is an important factor influencing the performance of laying hens. However, with pop-ularity of wet curtain and fans cooling system in recent years, the temperature in hen house can generally be controlled below 30℃ during summer, and therefore, the negative effects of the high temperature was often ignored in the actual production. The paper payed the attention on the harmful effects of high temperature especially cyclic high temperature on production of laying hens and summarized the measures to relieve the adverse effects of heat stress by changing the dietary energy and crude protein levels, in order to attach importance to the summer heat by researchers in production, and provide a scientific basis for reasonable diet preparation and breeding management of laying hens at the high temperature season.
