摘要
对农养不同品种山羊进行补饲育肥对比试验 ,结果表明 ,在牧草旺盛时节补饲 ,日增重公羊高于母羊 ,马头山羊高于本地山羊 ,尤其是本地母山羊日增重明显地低于本地公山羊及马头山羊母羊 (P <0 0 5 ) ,极显著低于马头山羊公羊 (P <0 0 1) ;本地公山羊日增重也显著低于马头山羊公羊 (P <0 0 5 ) ,同马头山羊母羊间没有差别 (P >0 0 5 )。在牧草枯衰时节补饲 ,日增重公羊仍高于母羊 ,本地母山羊同本地公山羊间没有显著差异 (P >0 0 5 ) ,但仍同马头山羊母羊间存在明显差别 (P <0 0 5 ) ;本地公山羊同马头山羊母羊间没有差异 (P >0 0 5 ) ,但与马头山羊公羊间存在差异 (P <0 0 5 )。在屠宰率、净肉率上 4组间没有明显差别 (P >0 0 5 )。经济效益马头山羊优于本地山羊 。
