摘　　要：为了分析利木赞牛对固原地区秦川牛的改良效果,本试验对固原地区秦川牛及其利杂群体的育肥性能进行了测定,结果表明:6月龄组利杂牛的日增重、精料采食量高于固原秦川牛(P<0.05)。相同年龄下,利杂牛的体重、体高、十字部高、胸围、管围等指标大于固原秦川牛(P<0.05或P<0.01)。18月龄组利杂牛140 d精料采食量高于固原秦川牛(P<0.05)。In order to analyze the crossing improvement of Limousin cattle to Qinchuan cattle in Guyuan, the fattening performance of Qinchuan cattle in Guyuan and crossbreed of Limousin ×Qinchuan cattle had been determined. The results showed that： The crossbreed of Limousin×Qinehuan cattle in the 6 month group had better average daily gain and concentrate feed intake than Qinchuan cattle in Guyuan （P〈0. 05）. The body weight, body height, height at hip cross, heart girth and circumference of cannon bone of the crossbreed of Limousin × Qinchuan cattle were higher than Qinchuan cattle in Guyuan at the same age significantly at the level of P〈0. 01 orP〈0.05, respectively. The crossbreed of Limousin × Qinchuan cattle in the 18 month group had higher concentrate feed intake of 140 days than Qinchuan cattle in Guyuan （P〈0.05）.
