摘　　要：2 8 8只 1日龄AA鸡随机分为三组 ,每组三个重复 ,研究在基础日粮中补充外源性谷氨酰胺对肉鸡早期 ( 0 - 4周 )生长性能的影响。结果表明 :第 2周内 0 .4%Gln组日增重比对照组和 0 .8%Gln组分别提高了 1 0 .5 %和 1 1 .5 % ( p >0 .0 5 ) ;第 2周和第 3周 0 .4%Gln组饲料转化率显著高于 0 .8%Gln组 ( p <0 .0 5 ) ;第 4周 0 .8%Gln组比对照组饲料转化率和0 .4%Gln组极显著降低 ( p <0 .0 1 )。Two hundred and eighty eight AA chickens of one day old were randomly divided into three groups,in order to investigate effect of exogenous glutamine on performance of AA chickens early.The results showed,the supplementation of 0.4% glutamine improved its average daily gain by 10.5% and 11.5%(P>0.05) compared with the controlling and the group of 0.8% glutamine during the second week.And obviously increased its feed efficiency compared with the group of 0.8% glutamine during the second and third weeks(P<0.05).In the fourth week compared with the controlling and the group of 0.4% glutamine,the group of 0.8% glutamine significantly decreased feed efficiency(P<0.01)?
