摘　　要：[目的]为探讨BMY牛及各种杂交牛在楚雄区域常规饲养状态下的生产性能,给该区肉牛改良方向提供科学依据。[方法]测定楚雄区域内各杂交牛的初生、6月龄体尺、体重。[结果]平均初生、6月龄体重以西本杂的为最高,分别为24kg、122.7kg,其次是短本杂交牛,分别为22.25kg、118.3kg,第三为BMY杂交牛,分别为20.15kg、98.8kg,第四是滇中牛,分别为15.90kg、75.5kg。[结论]不同品种杂交牛的生长性能都比滇中牛有很大的提高,改良效果好。[Objective]In order to explore the production performance of BMY cattle and different crossbreeds growth under the common feeding condition in Chuxiong zone and to provide scientific knowl edge direction of beef improvement for this region. [Method] The live weight and body size were measured at birth and 6 months of aged different crossbreeds in Chuxiong zone. [Result]The live weight result showed that the Simmental crossbred were the highest 122.7 kg;The second were Shorthorn crossbreed which at birth and 6 months of age which were 24 kg. were 22.25 kg and 118.3 kg; The third were BMY crossbred which were 20.15 kg and 98.8 kg;The forth were Middle Yunnan yellow cattle which were 15.9 kg and 75. 5 kg. [Conclusion]The growth performance were much higher than that of Middle Yunnan yellow cattle and showed the better beef improvement.
