草原红牛与利木赞杂交后增重效果的观察

Observation on Weight Gain Effect after Crossing of Red Steppe and Limousin

草原红牛育成后，肉用性能亟待提高，因此我们搞了用利木赞杂交的试验。试验从草原红牛与利木赞杂交后的育肥效果观察，可以看出：杂交后利×草Ｆ１的增重效果明显优于草原红牛，且适合于草原地区放牧饲养。

The meat property of Red steppe is to be improved after breeding,hence the cross test with Limousin is conducted.The fattening effect shows that after cross breeding,the weight gain effect of the progeny of Limousin and Red steppe F 1 is obviously better than that of Red steppe,and also it is suitable to graze in pastures.
