复合生物菌对肉仔鸡生产性能的影响

为了研究复合生物菌对肉仔鸡生产性能的影响，选用360只艾维茵肉仔鸡，随机分成4组，对照组饲喂基础日粮，试验组在基础日粮中分别添加金霉素（5 mg/kg）、1%和2%的复合生物菌，比较试验鸡的生产性能。研究结果表明，日粮中添加1%和2%的复合生物菌可显著提高肉鸡的日增重、饲料转化效率、成活率、屠宰率（P<0.05）；复合生物菌可替代抗生素金霉素提高肉鸡生产性能。

Effect of Compound Biological Bacterium on the Performance of Broiler

In order to study the effect of compound biological bacterium on the performance of broiler,360 Aiweiyin broilers were chosen and divided them into four groups randomly.The contrasting groups are fed with basic grain ration and the groups for experiment are fed with the basic grain ration with Chlortetracycline(5 mg/kg),1% and 2% compound biological bacterium.And then compare the performance of the broilers for experiment.The results showed that adding 1% and 2% compound biological bacterium to the basic gr...
