摘要
用植酸酶代替磷酸氢钙饲养肉鸡,早期(1～35日龄)不能完全满足雏鸡对磷的需要,但中后期可以满足。从整个饲养期来看,饲料中添加植酸酶代替无机磷饲养肉鸡,可以保证肉鸡的正常增重和按期出栏,有利于减轻鸡粪中磷对环境的污染。
In the early period(1-35days), it can't meet broiler chickens' need completely for phosphate if we use phytase instead of calcium hydrogen phosphate in broiler chickens' feeding, but after that period, it could. In the whole feeding time, the authors found that it could guarantee the broiler chickens' normal level of yield using phytase instead of calcium hydrogen phosphate in broiler chickens' feeding and it could relieve the phosphate population in broiler chickens' droppings.
