摘 要: 将 1 5 6羽 1日龄AA肉雏鸡随机分为对照组和试验组 ,对照组饲喂小麦基础日粮 ,试验组在基础日粮中添加 1‰木聚糖酶 ,试验期为 2 8d。结果表明 ,与对照组相比 ,试验组 4周内平均日增重提高 4.81 % (P <0 .0 1 ) ,料重比下降 5 .0 0 % (P <0 .0 5 )。 day-old broiler chicks were divided into two groups,of control and treatment with 6 replicates for each group.1‰ xylanase was added in wheat basal diet in treat group. The results showed that xylanase significantly increased ADG (average daily gain) by 4.81% (P< 0.01) and decreased F/G (feed/gain) by 5.00%(P<0.05) for treat group within 4 weeks.
