摘要
对抗热应激添加剂Ⅱ和Ⅲ对肉鸡的影响进行了研究，结果表明这些饲料中的添加剂可明显地防止热应激。添加剂Ⅲ在０．２２５％含量时效果最好，对３５－４２日龄仔鸡可增重８．４２％，对４３－４９日龄仔鸡可增重８．２８％，对１４－４９日龄仔鸡饲料报酬率增高２７．９％，减少死亡１３．７２％，添加剂Ⅱ作用不如添加剂Ⅲ明显。
The effects of heat stress-preventing additive Ⅱ and Ⅲ on boilers were studied. The results showed that these additives in feed significantly prevented heat stress. Additive Ⅲ in feed at the level of 0.225%(W/W) gave the best results. It increased the body weight gain by 8.42% for the 35￣42 days old chickens (P<0.05) , and by 8.28% for the 43￣49 days old. For 14-49 days old chickens, increased the ratio of feed / body weight gain by 279% and decreased the death ratio by 13.72%(P<0.05) .The efficiency of additive Ⅱwere not so obviously as additive Ⅲ.
