鲁西黄牛与其杂交牛育肥性能对比试验

Comparison on Fattening Performance between Luxi Yellow Cattle and Hybrid Cattle with Luxi Yellow Cattle as A Parent

鲁西黄牛、西鲁(西门塔尔×鲁西黄牛)、利鲁(利木赞×鲁西黄牛)育肥试验中,西鲁、利鲁和鲁西黄牛的日增重分别达到1204,1117,1058g,每增重1kg的饲料成本分别为5.98,5.38,6.15元。西鲁、利鲁的日增重和单位的增重饲料成本与鲁西黄牛对比均存在显著差异。试验证明,利用肉牛杂交改良鲁西黄牛,可显著提高生产效率。

As shown by the fatting experiment,the daily weight gain of Luxi Yellow cattle,Xilu cattle （Simmental × Luxi） and Lilu cattle （Limousin × Luxi） was 1 204,1 117 and 1 058 g,respectively.The feed cost for 1 kg weight gain of the three breeds was 5.98,5.38 and 6.15 Yuan,respectively.Both the daily weight gain and the feed cost for 1 kg weight gain were significantly different between the Luxi Yellow cattle and the Xilu cattle or between the Luxi Yellow cattle and the Lilu cattle,which showed crossbreeding of Luxi Yellow cattle with beef cattle can greatly increase production efficiency.
