摘　　要：本文综述了环境低温和高温对生长猪生产性能的影响。低温下,随着环境温度的降低,采食量呈线性增加;高温降低采食量,随着环境温度的升高,采食量呈二次函数下降。低温对日增重的影响较小,在10℃以上,自由采食的猪,其日增重几乎不受影响,而高温对其日增重的影响极大,尤其是30℃以上的高温。低温和高温均降低饲料转化率。高温对养猪的负面影响大于低温。The review summarized the effects of environmental temperature on the performance of growing pigs. The voluntary food intake （VFI） of growing pigs in low temperature was linearly increased with environmental temperature dropping down from lower critical temperature （LCT） ; however, hot temperature resulted in reduced food consumption. The average daily gain （ADG） was slightly affected as growing pigs exposed in over 10℃ cold temperature, while it decreased markedly in hot temperature, especially over 30℃, The feed conversion ratio both decreased in low and high temperature.
