摘要
研究了中草药提取物"益绿素"对鸡生长性能的影响。试验选用160只1日龄健康草杂鸡,随机分为两组,即:试验组和对照组,益绿素分别按0和0.2%添加到对照组和试验组鸡的基础日粮中,试验期为30天,在7、14、21和30日龄早晨空腹称重,每天记录饲料消耗量,试验全期观察试验鸡的健康状况。试验结果表明,试验组鸡的增重较对照组高,试验组鸡体重较对照组在第二周、第三周和第四周分别提高2.04%,5.88%,6.34%差异显著(P<0.05);试验组经济效益较对照组提高了2.14%。中草药提取物"益绿素"作为饲料添加剂对草杂鸡生长性能有明显的促进作用。
The effects of Chinese Herbs Extracts on chicken＇ s production performance were tested in experiment. 160 one-day age chickens were selected in this experiment and was divide into random contrast group and experiment group,80/group, the Chinese Herbs Extracts （Yi Lvsu） of 0 and 0.2% added to the contrast group and the experiment group＇ s basic diet in 7th day for 30 days long. It has weighed on an empty stomach in 7th, 14th, 21st and 30th morning. The effects of Chinese Herbs Extracts （Yi Lvsu） on chicken＇ s production performance were observed in experiment. The result reveals that the experiment group increases were weight gain day than the contrast group. The difference is remarkable（P〈0.05） when the weight of the experiment group have went up 2.04%, 5.88% and 6.34% than the contrast group in the 2nd, 3rd and 4th week. The economic efficiency of experiment group has raised 2.14%. This experiment results prove the Chinese Herbs Extracts （Yi Lvsu） as feed additives on chicken growth performance in a clear role in promoting.
