摘　　要：选择5周龄、7周龄新西兰白兔各32只,各自随机分成4组(对照组、试验组3组),每组两个重复,每个重复4只,对照组日粮中添加20%的米糠,试验1、2、3组日粮中不添加米糠,分别添加40%、30%、20%的花生藤粉,研究不同比例花生藤粉代替米糠对不同阶段肉兔生产性能的影响。结果表明:①5周龄阶段,试验3组的日增重分别比对照组、试验1组、试验2组提高19.1%、26.0%、10.9%,与对照组差异显著(P<0.05),与试验1组有极显著差异(P<0.01);饲料转化率也较其他3组分别提高了14.7%、6.0%与7.2%,说明添加20%的花生藤粉代替20%的米糠对该阶段肉兔生产性能有显著效果。②7周龄阶段,试验2组的日增重较对照组、试验1组、试验3组提高了5.6%、12.2%、12.3%,但差异不显著(P>0.05);饲料转化率也较其他3组分别提高了11.1%、20.0%、14.4%,说明添加30%的花生滕粉代替20%的米糠对该阶段肉兔有更好的生产效果。总之,花生藤粉代替米糠饲喂肉兔取得显著的效果,是一种值得开发利用的粗饲料。To sduty on effects of different proportions of peanut vine powder on production performance of meat rabbit by instead of rice bran, 32 New Zealand rabbits of 5-week-old and 7-week-old were selected, respectively, then they were randomly divided into four groups （lcontrol group, 3 testing groups）, there were two repeat in each group and each repeat contained 4 animal. The diet of control group supplemented with 20% of the rice bran. Diet of testing group 1, 2 and 3 added 40%, 30%, 20% of the peanut vine powder without rice bran. The results showed that： （1） On the stage of 5-week-old, the daily gain weight of testing group 3 were higher 19.1%,26.0%,10.9% than control group, testing group 1 and 2 respectively, and there were more significant difference between it with the control group （P 〈0.05） and extremely significant difference with testing group I（P 〈0.01）. Feed conversion rate of teating group 3 were increased by 14.7%, 6.0% and 7.2% than that of the other three groups. This study indicated that there was a significant effect to production performance of meat rabbit on the stages by adding 20% of the peanut vine powder in the diet in- stead of 20% of rice bran. （2） On the stage of 7-week-old, the daily gain weight of testing group 2 were higher 5.6% ,12.2%, 12.3% than control group, testing group 1 and 3, respectively, but the difference was not significant （P〉 0.05）. Feed conversion rate in testing group 2 were increased by 11.1%, 20.0%, 14.4% than other three groups. The result indicated that add 30% of peanut vine powder instead of 20% of rice bran on the stage of the production of meat rabbits had a better effect. In short, peanut vine powder as one of the roughage was benefit for production performance of meat rabbit by instead of of rice bran and worthy of development and utilization.
