乳酸芽孢杆菌制剂对AA肉鸡生产性能的影响

Effects of Lactobacillus sporogenes on production performance in AA broilers

本试验研究在日粮中分别添加200mg/kg乳酸芽孢菌制剂和50mg/kg土霉素,对1～49日龄AA肉鸡生产性能的影响。结果表明,乳酸芽孢菌制剂组和土霉素组的全期平均日增重比对照组提高15.29%和9.10%(P<0.05),乳酸芽孢菌制剂组比土霉素组提高5.67%(P>0.05);乳酸芽孢菌制剂组和土霉素组的全期料肉比分别比对照组降低9.09%和7.36%(P<0.05),乳酸芽孢菌制剂组比土霉素组低1.87%(P>0.05);各组成活率差异不显著。

The experiment was conducted to study the effects of Lactobacillus sporogenes on production performance of AA broiler.The results showed that：compare with control group,the daily gain of Lactobacillus sporogenes and terramycin group were significantly improved by 15.29 % and 9.10 % （P 〈 0.05）,and the daily gain of the Lactobacillus sporogenes group was 5.67 % higher than that of the terramycin group （P 〉 0.05）;The feed/gain ratio of Lactobacillus sporogenes and terramycin groups were reduced significantly by 9.09 % and 7.36 %（P 〈 0.05）,and the feed/gain of Lactobacillus sporogenes group was 1.87 % lower than that of the terramycin group（P 〉 0.05）;The survive rate of each group had no significant difference.
