摘要
为大力推进燕麦草在肉牛养殖中广泛应用,通过不同比例燕麦干草与青贮玉米饲喂肉牛试验,筛选出最佳饲喂模式。选用15头体重和体况相似的西门塔尔杂交公牛在精料相同,精粗比3∶7条件下,不同比例燕麦干草和青贮玉米饲粮组合中,40燕麦干草60青贮玉米饲喂育肥肉牛平均日增重达到2165 g,料肉比达到46.25,经济效益均高于其它各组。在实际饲喂肉牛中,要大力推广燕麦干草40玉米青贮60精料的饲料饲喂模式。
In order to promote the wide application of oat hay in beef cattle breeding,the optimal feeding mode was selected through experiments of different proportions of oat hay and silage corn.15 Simmental hybrid bulls with similar body weight and body condition were selected.Under the condition of the same concentrate and forage to roughage ratio of 30:70 and different proportions of oat hay and silage corn,the average daily gain of fattening beef cattle fed with 40%oat hay and 60%silage corn was up to 2165 g,and the feed to meat ratio reached 46.25,the economic benefits were higher than those of other groups.In the actual feeding of beef cattle,the feed mode of 40%oat hay and 60%corn silage and concentrate should be promoted vigorously.
