摘　　要：文章旨在探讨科宝500和爱拔益加(AA)白羽肉鸡生产性能的差异。试验以科宝500和爱拔益加(AA)白羽肉鸡为研究对象,测定1~6周龄两个品种的平均采食量、平均体重、平均日增重、料重比、死淘率以及欧洲效益指数,分析比较两品种间生产性能的差异变化。结果表明:(1)科宝500肉鸡平均采食量前期变化较大,2周龄时显著高于AA肉鸡(P<0.05),但3周龄显著低于AA白羽肉鸡(P<0.05),整个试验期(1~6周龄),科宝500肉鸡平均采食量高于AA肉鸡,但差异不显著(P>0.05);(2)7和35日龄时,科宝500肉鸡平均体重显著大于AA肉鸡(P<0.05),5周龄时,科宝500肉鸡平均日增重显著高于AA肉鸡(P<0.05),而其他周龄及整个试验期(1~6周龄),科宝500肉鸡平均体重和平均日增重均高于AA肉鸡,但差异均不显著(P>0.05);(3)各周龄及整个试验期(1~6周龄)科宝500肉鸡料重比均低于AA肉鸡,但差异均不显著(P>0.05);(4)4周龄时,科宝500肉鸡死淘率显著高于AA肉鸡(P<0.05),而其他周龄及整个试验期(1~6周龄),科宝500肉鸡死淘率高于AA肉鸡,但差异均不显著(P>0.05);(5)欧洲效益指数(EPI)方面,科宝500肉鸡高于AA肉鸡,但差异不显著(P>0.05)。综合分析,科宝500肉鸡生产性能及养殖效益优于AA肉鸡。The purpose of this experiment was to explore the differences of the performance betweenCobb 500 and AA white feather broilers.Cobb 500 and AA white feather broilers were took as the research objects,the average feed intake,weight,daily gain,feed-meat ratio,mortality rate and European benefit indexwere determined,and the differences were compared between Cobb 500 and AA white feather broilers.The results showed that,(1)The average feed intake of Cobb 500 broilers changed greatly in the early stage,and at the age of 2 weeks,it was significantly higher than that of AA broilers(P<0.05),while at the age of 3weeks,it was significantly lower than that of AA broilers(P<0.05),but during the whole experimental period(1~6 weeks),the average intake of Cobb 500 broilers was higher than that of AA broilers,but the difference was not significant(P>0.05);(2)At the age of 7 and 35 days,the average weight of Cobb 500 broilers was significantly higher than that of AA broilers(P<0.05),and at the age of 5 weeks,the average daily gain of Cobb 500 broilers was significantly higher than that of AA broilers(P<0.05),while the averageweight and daily gain of Cobb 500 broilers was higher than that of AA broilers at other weeks and during the whole experimental period(1~6 weeks),but the difference was not significant(P>0.05);(3)The feed-to-weight ratio of Cobb 500 broilers was lower than that of AA broilers in each week and the whole experimental period(1~6 weeks),but the difference was not significant(P>0.05);(4)At the age of 4 weeks,the mortality rate of Cobb 500 broilers was significantly higher than that of AA broilers(P<0.05),while at other weeks and throughout the experimental period(1-6 weeks),the mortality rate of Cobb 500 broilers was higher than that of AA broilers,but the difference was not significant(P>0.05);(5)The European benefit index(EPI)of Cobb 500 broilers was higher than that of AA white feather broilers,but the difference was not significant(P>0.05).Comprehensive analysis:the production performance and breeding benefit
