| 摘要: |
| 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，必须提供一定的的补充饲料（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％，经济效益显著。 |

| Abstract: |
| 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. |
