摘　　要：为探讨山毛豆(Tephrosia candida)草粉对肉兔的饲用价值,将60只新西兰青年肉兔分为5组,分别添加0%(对照),10%,20%,30%和40%的山毛豆草粉制成全价颗粒饲料,饲喂90d后测定各组饲料的营养成分及肉兔采食量、日增重、料重比和屠宰性能。结果表明:山毛豆营养生长期粗蛋白含量为17.77%,肉兔对山毛豆中粗蛋白的消化率为78.09%,山毛豆的可消化总养分为56.18%。与对照组相比,添加20%草粉日增重达到20.80g.d-1(P<0.01);料重比为4.45∶1(P<0.05);屠宰率为57.78%(P<0.01);单位kg增重平均最低饲料成本差异显著(P<0.05)。因此,添加20%山毛豆草粉制成全价颗粒饲料可显著提高肉兔的生产性能和养殖效益。In order to assess the feeding value of Tephrosia candida meal on meat rabbits, sixty New Zeal- and rabbits divided into five groups were fed using meal containing 0%, 10%, 20%, 30% and 40% T. candida, respectively. Then nutrient components, average daily intake, daily weight gain, feed con- version ratio and slaughtering performance were determined. Results showed that the crude protein con- tent of T. candida in the stage of vegetative period was 17.77 %. The apparent digestibility of crude pro- tein of T. candida was 78.09%. The total digestible nutrition was 56.18%. The daily weight gain of test- ed rabbits achieved 20.80 g d 1 ,the feed convectional ratio was 4.45 ： 1,the slaughtering rate was 57. 78% and the unit weight gain cost had extremely significant difference comparing to control group when 20% T. candida was added （P〈0.05）. Therefore, the pellet feed adding 20% T. candida could improve the producing performance and the profit of meat rabbits.
