摘　　要：本试验旨在研究宠物级鸡肉粉替代鱼粉对黄鳝(Monopterus albus)生长性能、肠道消化酶活性及血清生化指标的影响。以宠物级鸡肉粉分别替代基础饲料中0(P PBM0组,作为对照组)、15%(P PBM15组)、30%(P PBM30组)、45%(P PBM45组)、60%(P PBM60组)的鱼粉,配制5种等氮等能的试验饲料。选取900尾初始体重为(26.67±0.05)g的黄鳝,随机分为5个组,每组设3个重复,每个重复60尾,养殖试验持续8周。结果显示:随着宠物级鸡肉粉替代鱼粉比例的升高,黄鳝的增重率呈下降趋势,饲料系数呈上升趋势,P PBM45、P PBM60组的增重率较对照组显著降低(P<0.05),同时P PBM60组的饲料系数较对照组显著升高(P<0.05)。各替代组黄鳝的体成分均与对照组无显著差异(P>0.05)。与对照组相比,各替代组黄鳝肠道脂肪酶活性均显著降低(P<0.05)。当替代比例超过45%时,血清中高密度脂蛋白、低密度脂蛋白、尿素氮、补体3、补体4含量以及谷草转氨酶和谷丙转氨酶活性均较对照组显著升高(P<0.05)。P PBM60组血清中白蛋白和甘油三酯含量均显著高于对照组(P<0.05)。由此得出,本试验条件下,宠物级鸡肉粉替代鱼粉比例不超过45%时,对黄鳝的生长性能以及生理功能无负面影响。A 10 week feeding trial was conducted to evaluate the effects of replacing fish meal(FM)with pet grade poultry by product meal(P PBM)on growth performance,intestinal digestive enzyme activities and ser um biochemical indexes of rice filed eels(Monopterus albus).In this experiment,five isonitrogenous and isoenergetic diets were formulated by replacing 0(P PBM0 group,as control group),15%(P PBM15 group),30%(P PBM30 group),45%(P PBM45 group)and 60%(P PBM60 group)fish meal with pet grade poultry by product meal in a basal diet,respectively.A total of 900 rice filed eel with an initial average body weight of(26.67±0.05)g were randomly allocated into 5 groups with 3 replicates per group and 60 fish per replicate.The results showed as follows:with the replacement ratio of fish meal by pet grade poultry by product meal increasing,the weight gain rate showed a decrease trend,and the feed conversion rate showed an increase trend.The weight gain rate of rice field eel in the P PBM45 and P PBM60 groups was significantly lower than that in the control group(P<0.05),and the feed conversion rate of rice field eel in the P PBM60 group was significantly higher than that in the control group(P<0.05).Compared with the control group,the body composition of rice field eel in the replacement groups had no significant difference(P>0.05),but the intestinal lipase activity of rice field eel in the replacement groups was significantly decreased(P<0.05).When the replacement ratio exceeded 45%,the contents of serum high density lipoprotein,low density lipoprotein,urea nitrogen,complement 3,complement 4,as well as the activities of serum glutamic oxalacetic transami nase and glutamic pyruvic transaminase were significantly increased compared with the control group(P<0.05).The serum albumin and triglyceride contents in the P PBM60 group were significantly higher than those in the control group(P<0.05).To sum up,under the condition of this experiment,pet grade poultry by prod uct meal replaced less than 45%fish meal has no negative effect on
