试验采用单因素梯度设计,在基础饲料中分别添加0 mg/kg、100 mg/kg、200 mg/kg和400 mg/kg的复合酶制剂,每个处理设3个重复,饲养异育银鲫（初始重6.7 g左右）56 d后,测定其生长速度,并分析了SOD和溶菌酶活性。结果表明：添加200 mg/kg复合酶制剂组异育银鲫的增重率和特定生长率最大,显著大于对照组,同时该组异育银鲫的饲料系数最低,显著低于对照组。添加复合酶制剂可显著提高异育银鲫血清、脾脏、肝胰脏、头肾SOD活性和血清、头肾、脾脏溶菌酶活性。

A feeding study was performed to investigate the possible performance of enhancing effects of multi-enzyme additive in Carassius auratus gibelio,as well as their influence on the superoxide dismautase activity （SOD） and lysozyme activity of fish for 8 weeks.Three hundred and sixty individuals（initial body weight 6.71 g per fish） were allotted to four dietary treatments in triplicate：a control group and three experimental groups which were supplemented with 100 mg/kg,200 mg/kg,and 400 mg/kg multi-enzyme additive in feed.It was found that in...
