摘　　要：选择健康生长肉兔80只，随机分成4组，每组20只。各组随意采食多花黑麦草Lolium multflorum，配合饲料限制不同量。试验37 d后表明，在兔日粮中加入25.95%-35.89%的多花黑麦草（以干物质计），对肉兔增重无显著影响，饲喂多花黑麦草可明显地节约精料，能有效降低成本、增加收入。试验肉兔每增重1 kg，1组比4组节约配合饲料0.79 kg、减少配合饲料消耗37.61%，增加收入达32.74%，取得显著的经济效益。Eighty rabbits were grouped into 4 randomly with 20 for each group. Annual ryegrass was fed to the animals together with different concentrate rations. 37 days after, 25.95%-35.89% of annual ryegrass （dry matter） in the ration had no significant effect on rabbit weight gain, but it could significantly save the concentrate and reduce cost. For 1 kg live weight gain, group 1 saved 0.79 kg concentrate （37.61%） and increased 1.49 yuan income compared with group 4. The economic profit was significant.
