Abstract

选择1日龄AA肉鸡630羽,随机分为3组.1组(对照组)饲喂基础日粮,2、3组分别在基础日粮中添加200mg/kg、300mg/kg的半胱胺(CS).试验结果表明:与对照组相比,肉鸡0～3周龄时200 mg/kg CS组的平均日增重提高5.20%(P＜0.05),300 mg/kg CS组提高1.90%(P＞0.05);4～6周龄时200mg/kgCS组的平均日增重提高5.27%(P＜0.05),300mg/kg CS组提高6.31%(P＜0.05);全期(0～6周龄)200mg/kg CS组的日增重提高5.25%(P＜0.05),300mg/kgCS组提高5.03%(P＜0.05).
