【Abstract】 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)?更多还原
