摘要
将360羽14日龄的艾维茵肉鸡随机分为4组,试验Ⅰ、Ⅱ、Ⅲ组分别添加复合酶制剂0.1%、0.15%和0.2%于饲料中,与对照组进行比较,经28d饲养试验,结果表明:与对照组比较,试验Ⅰ组的日增重提高9.87%,饲料报酬提高10.24%;试验Ⅱ组的日增重提高15.80%,饲料报酬提高19.51%;试验Ⅲ组的日增重提高16.50%,饲料报酬提高20.49%。试验组显著优于对照组。
360 14-day-old chickens were randomly divided into 4 groups： trial group Ⅰ , trial group Ⅱ , trial group Ⅲ and control group. With adding 0.1%, 0.15% and 0.2% complex enzyme additive into the feed of the three trial groups, adding nothing into that of the control group, after 28 days of feeding test, it appears that： comparing with the control group, trial group Ⅰ was improved 9.87% on average daily gain, 10.24% on feed efficiency; trial group Ⅱ was improved 15.80% on average daily gain, 19.51% on feed efficiency; trial group Ⅲ was improved 16.50% on average daily gain, 20.49% on feed efficiency. The trial groups were significant super to the control group.
