摘　　要：为研究水解羽毛粉替代鱼粉对异育银鲫(Carassius auratus gibeilo)生长及体组成的影响,试验用0%、1.5%、3%、4.5%和4.5%羽毛粉替代相应鱼粉蛋白,配制成5种等氮等能饲料,第5种饲料中添加0.2%赖氨酸和0.1%蛋氨酸。每种饲料投喂3个水族箱[试验鱼20尾,初始体重(7.57±0.11)g]。试验期47 d。结果显示:随水解羽毛粉水平升高,异育银鲫增重率、特定生长率和饲料转化率均呈下降趋势,但差异不显著(P>0.05)。1.5%水解羽毛粉替代组增重率和特定生长率最高。然而,水解羽毛粉显著影响了异育银鲫的蛋白质效率,用4.5%水解羽毛粉替代鱼粉时,蛋白质效率与对照组相比显著降低(从2.15降低到1.90)。水解羽毛粉替代鱼粉对鱼体水分、粗蛋白质、粗脂肪及灰分含量均无显著影响(P>0.05)。饲料中补充赖氨酸和蛋氨酸对其生长指标有一定改善作用。Hydrolyzedpoultry feather（HPF） was evaluated as a replacement of fish meal（FM） in a practical diet for gibel carp（Carassius auratus gibeilo）.FM were replaced by 0%,1.5%,3%,4.5%,and 4.5% of HPF respectively.The last diet was supplemental with 0.2% L-lysine and 0.1% DL-methionine.Juvenile gibel carp with（7.57±0.11）g body weight were reared in an indoor,semi-closed recirculating system.Each diet was randomly fed to triplicate groups of 20 fish per tank for 47 days.At the end of the feeding trial,the weight gain,specific growth rate（SGR） and feed efficiency ratio（FER） declined with inclusion levels of HPF increased,but there were no significant differences（P〈0.05）.Protein efficiency ratio（PER） in 4.5% HPF group significantly lower than that in 0% HPF group（P〈0.05）.There was no significant effect on fish body moisture,crude protein,crude fat and crude ash content by hydrolyzed feather meal substitute fish meal（P〈0.05）.The supplementation of lysine and methionine in the feed could improve the growth index.
