柠檬酸渣发酵料对肉鸡生产性能及成活率的影响

研究了不同比例的柠檬酸渣发酵料代替基础日粮对肉鸡生产性能及成活率的影响。结果表明：全期增重及日增重,10%的替代组较对照组分别降低1.29%（P〉0.05）、1.06%（P〉0.05）,5%、15%、20%、25%替代组分别比对照组提高1.29%（P〉0.05）和14.19%（P〈0.01）、1.29%（P〉0.05）和9.03%（P〈0.05）、1.43%（P〉0.05）和13.85%（P〈0.01）、1.99%（P〉0.05）和8.71%（P〈0.05）;料肉比,5%、10%、20%替代组较对照组高2.88%（P〉0.05）、2.88%（P〉0.05）、0.82%（P〉0.05）,15%、25%替代组较对照组降低15.64%（P〈0.01）、8.23%（P〈0.05）;试验组成活率均达到了100%,比对照组高2.5%（P〉0.05）。由此可见,柠檬酸渣发酵料有提高肉鸡生产性能及增强机体抵抗力的作用。

Effect of Fermented Citric Acid Slag on Productive Performance and Survival Rate of Broilers

Effect of different concentration of fermented citric acid slag as a substitute for basal feed on productive performance and survival rate of broilers were studied.Result showed that the total gain weight and daily gain weight of 10 % concentration group decreased by 1.29 %(P>0.05) and 1.06 %(P>0.05) compared with that of control group,respectively.Total gain weight of 5 %,15 %,20 % and 25 % concentration groups improved by 1.29 %(P>0.05),14.19 %(P<0.01),1.29 %(P>0.05) and 9.03 %(P<0.05) respectively.And daily gain weight of these groups improved by 1.43 %(P>0.05),13.85 %(P<0.01),1.99 %(P>0.05) and 8.71 %(P<0.05),respectively.Ratio of feed to meat in 5 %,10 % and 20 % concentration groups were 2.88 %(P>0.05),2.88 %(P>0.05) and 0.82 %(P>0.05) higher than that of control group,respectively.But Ratio of feed to meat of 15 % and 25 % concentration groups was 15.64 %(P<0.01) and 8.23 %(P<0.05) lower.Survival rate of treated groups all reached 100 %,which was 2.5%(P>0.05) higher than that of control group.All these indicated that fermented citric acid slag improved the productive performance and resistance of broilers.
