玉米秸秆青贮饲料肥育肉牛合理补饲方案的试验研究

Experiment Research on Reasoned Supplemental Feed Scheme of Corn stalk Silage as Element Ration in Beef Cattle's Fattening

玉米秸秆青贮饲料作为反刍动物基础日粮时 ,其营养成分难以充分满足肉牛肥育过程中的养分需求 ,必须提供一定量的补充饲料 (精料补充料 )。为此 ,研究提出了 2种补饲方案 ,并进行了生产性饲喂试验。试验结果表明 ,应用 2种补饲方案可使肉牛的平均日增重分别提高 9.48和 38.79 ,饲料转化率分别提高7.9和 36.43 。

While ensilage becomes element ration of ruminant, its nutri ti onal ingredient can not sufficiently satisfy the nutritional requirements of bee f cattle's fattening. The supplemental feed is necessary. Two reason supplementa l feed schemes for beef cattle have been put forward. At the same time, feeding experiment has been done on the breeding farm of Xingsheng in Shunyi, Beijing. T he results showed that the application of two reason supplemental feed schemes h as respectively advanced 9 48% and 38 79% of daily mean gain and 7 9% and 36 43% of feed conversion efficiency for beef cattle. Economy benefit is obvious.
