摘要 通过大规模的肉鸡试验证实添加克洛生的效果要优于添加亚甲基双水杨酸杆菌肽(BMD)的效果,BMD是一种抗生素生长促进剂。选取20个农场的120 948羽肉鸡进行试验,其中A组包括10个农场的49 308羽肉鸡,添加200 g/t的克洛生11粉剂,B组包括其他10个农场的71 640羽肉鸡,添加500 g/t的BMD。结果表明,与B组相比,克洛生能显著改善饲料转化率及校正饲料转化率(P<0.05),两个参数分别改善了6个百分点和11个百分点。同时,克洛生还能使欧洲效率因子(EEF)提高34个百分点。添加克洛生还能显著降低每羽肉鸡的生产成本、用药费及饲料费用,显著增加日增重(P<0.05)。从整体效果看,克洛生能使肉鸡日增重提高9.29%,每千克活鸡能得到2.09卢比的收益。
