摘　　要：用新诺顿豆Neonotonia wightii、柱花草Stylosanthes guianensiscv.Reyan No.2、菊苣Cichorium inty-bus、甘薯藤Ipomoea batatas鲜草分别与坚尼草Panicum maxiumum鲜草混合饲喂肉兔效果研究表明:肉兔对不同混合的各饲草的采食率从低到高顺序为坚尼草(55.3%)<柱花草(68.6%)<新诺顿豆(76.2%)<甘薯藤(83.0%)<菊苣(91.5%);肉兔对新诺顿豆+坚尼草、菊苣+坚尼草、甘薯藤+坚尼草混合饲草的消化率间差异不显著,均与柱花草+坚尼草混合饲草消化率差异显著;菊苣+坚尼草混合饲喂肉兔平均日增重及利用率较高,分别与新诺顿豆+坚尼草、柱花草+坚尼草混合差异显著,与甘薯藤+坚尼草混合差异不显著,新诺顿豆+坚尼草、柱花草+坚尼草混合饲喂肉兔平均日增重及利用率均与甘薯藤+坚尼草混合差异显著;菊苣+坚尼草混合饲喂肉兔在经济效益方面最佳,比甘薯藤+坚尼草提高40.68%。Fresh Neonotonia wightii, Stylosanthes guianensis cv. Reyan No. 2, Cichorium intybus, Ipomoea batatas and Panicum maxiumum were mixed to feed rabbit and the feeding effectiveness revealed that intake rate of P. maxiumum was the lowest （55.3%0）, followed by S. guianensis cv. Reyan No. 2 （68. 6%）, N. wightii（76. 2%） , Ipomoea batatas（83%）, and C. intybus（91. 5%） in sequence. There was no significant digestion difference among N. wightii ＋ P. maxiumum, C. intybus ＋ P. maxiumum, I. batatas ＋ P. maxiumum; but they significantly differed from S. guianensis cv. Reyan No. 2 ＋ P. maxiumum. Average daily live weight gain of rabbit and feed use efficiency were higher in C. intybus ＋ P. maxiumum,showing significant difference from N. wightii ＋ P. maxiumum and S. guianensis cv. Reyan No. 2 ＋ P. maxiumum. But they had no remarkable difference from I. batatas ＋ P. maxiumum. C. intybus ＋ P. maxiumum had the highest economic benefits, 40. 68% higher than I. batatas ＋ P. maxiumum.
