摘　　要：选择年龄相近 ,健康无病 ,体重约 1kg的新西兰白兔 80只 ,根据体重、性别按组间相似的原则分为 4组 ,每组 2 0只。结果表明 ,试兔平均日增重 4组间有明显差异 ,饲料报酬和单位增重的饲料成本 ,以试验 2组和试验 3组最好 ;试验 1 ,2 ,3组试兔干物质、能量和粗蛋白质的消化率均显著高于对照组 (P <0 0 1 ) ,而试验组间无显著差异 (P <0 0 5) ,3个试验组的胴体重和屠宰率都显著高于对照组 (P <0 0 1 ) ,但以试验 2组最高 ;肌肉pH值和系水力各组之间无显著差异 (P <0 0 5)。Eighty rabbits of New Zealand White,about l kg weight,were divided into 4 groups similarly.The results showed that there was signifficant difference in average daily gain among these four groups,the average gain of group 2 and group 3 were higher than that of group l and control ( P <0.01);The digestibility of dry matter(DM),gross energy(GE),crude protein(CP),and crude fiber(CF) in group 1,group 2 or group 3 were higher than that in control ( P <0.01);The carcass weight and dressing percentage of three tested groups were higher than that of control( P <0.01),but no significant difference exists in the pH value and holding water of muscle between each group( P <0.05).
