中文摘要:

      [目的]饲草在肉牛养殖中发挥着重要作用，通过牛体增重对比不同饲草及其配比喂养西门塔尔肉牛效果，以确定较优的青贮甜高粱和全株饲用玉米的配比。[方法]在冬季温室养殖条件下，设计5组配比的青贮甜高粱和全株饲用玉米饲喂西门塔尔肉牛，定期称量牛体增重，并分析各试验组养殖效益。[结果]试验结果显示：青贮甜高粱和全株玉米喂养西门塔尔肉牛总增重量平均达90.95kg，最小为84.63kg，日平均增重1.01 kg/d，最小增重0.89kg/d，平均增重率为38.66%。比较投入和整个试验期收益的稳定性，青贮玉米秸秆30%和青贮甜高粱70%效益较好，平均增重率为40.48%。[结论] 青贮玉米和甜高粱秸秆搭配舍饲喂养西门塔尔肉牛都可实现稳定增重，效益优于单独应用。

英文摘要:

      [Objective] Forage plays an important role in the development of barn cattle industry. The effects of feeding Simmental beef cattle with different forage rations were compared by weight gain, so as to determine the optimal forage ration of silage sweet sorghum and whole plant of corn. [Method] Simmental beef cattle were fed by 5 tests with different proportions of sweet sorghum and whole plant corn, and the effect of weight gain of beef cattle under greenhouse conditions in winter was compared, and the benefits were analyzed. [Result] The results showed that the average weight gain of Simmental beef cattle fed with silage sweet sorghum and whole plant corn was 90.95 kg, the minimum was 84.63 kg, and the average weight gain was 1.01 kg / d , and minimum daily gain was 0.89 kg / d, and the ratio of weight gain was 38.66%. Comparing the difference and stable between the input during the whole experimental period, the benefit with ratio of weight gain 40.48% of the forage ration of 30% whole plant silage corn and 70% silage sweet sorghum straw was better. [Conclusion] It could be rapid weight gain that silage corn and sweet sorghum straw increase ration feeding Simmental beef cattle, and the benefit of the combination of silage corn and sweet sorghum straw was better than that of single application.
