种草养畜——农区畜牧业持续稳定发展的必然趋势

我国广大农区只有将牧草纳入农田耕作制，走以草养畜、以草或畜禽粪便养地、用养结合的农牧业共同发展的生态农业道路，才能使畜牧业突破传统种植业生产的饲料数量有限、蛋白质含量低的双重约束，为人们提供满足营养需要的畜产品。

Growing Grazing Grass-the Inevitable Trend for Animal Husbandry's Sustainable Development in Agriculture Area

This paper proposed that growing grazing grass should be listed in the agenda for crop field cultivation system in rural areas in China. The eco- agriculture model, with growing grass for feeding livestocks and using the livestocks' feces for keeping the crop fields' fertility, is a better way than traditional platation production. It could provide much more feed with higher protein contents in it, and this, in turn, could promote animal husbandry development and thus more and better livestock products could be provided to meet people's need in nutrition.
