[目的]通过饲喂比较试验，以期优化最佳肉牛配方。[方法]将24头试验牛平均分为A、B、C三组，每组10头，分别饲喂不同配方的饲料。[结果]表明：A组配方增重效果最明显，平均日增重达到1．19kg；B组配方增重较A组低0．06kg，平均日增重1．13kg；C组最少，平均日增重1．11kg。其结果组内个体间增重效果差异不显著（P〉0．05），A与B、C组间差异极显著（P〈0．01）。进一步作新复极法（LSR）检验，结果如表6，配方B、C增重效果不显著。而A与B、C均达到极显著水平。A组饲料报酬较高，料肉比12．39：1；C组次之，料肉比12．41：1；B组最低，料肉比12．75：1。A组饲料成本相对于B组、C组要低。[结论]从本地比较丰富的饲草料中，选择适口性好、易消化、营养水平相对较高的饲草料经过合理搭配，可提高肉牛育肥效益。%[Objective]In order to explore the best ods]24 Qin miscellaneous with similar body weight, feed formulation by feeding comparative test. [Meth physical development and in good health were ran groups. And the average daily gain was 1.19 kg. Group B was 1.13 kg,which was less 0.06 kg than that of group A. Group C was the worst, and the average daily gain weight was 1.11 kg. The wei individuals within groups was not significant (P〉0.05). The differences between A and ght gain effect on B,A and C were significant (P〈0.01). By new repolarization method (LSR) test, the weight gain effect of formula B and C was not significant. But between A and B, A and C, the difference was highly significant. Group A had higher feed efficiency, and the feed conversion ratio was 12.39 : 1, then followed C group, and the feed conversion ratio was 12.41 : 1;B group had the lowest feed conversion ratio of 12. 75 : 1. Feed cost of group A was lower compared to group B and C. [Conclusion]The compound of the local abundant forage, the palatability, digestible, nutrient levels relatively high forage after a reasonable match, could improve beef cattle fattening benefit.
