摘要
近年来华北平原农区畜牧业发展迅速，但优质青绿饲草的不足已经成为畜牧业发展的制约因素．为此在农区发展优质青绿饲草是满足畜牧业发展的需要。牧草蛋白质含量和赖氨酸含量都比秸秆等传统饲料高，一般禾本科干草的蛋白质含量为13％-15％，豆科牧草为18％-24％，并且牧草中所含的蛋白质更容易被家畜消化吸收。本文试验研究了几种适宜华北平原种植的优质牧草的生物学特性，结合华北平原牧草种植与利用现状．提出了适宜华北平原的8种牧草和种植模式。并对平原不同生态类型区的畜牧业产业发展方向作出了规划设想，即建设山前平原青绿饲草产业带，促进奶牛业发展；建立海河低平原和黄河三角洲两个饲草业出口基地。以大城市和亚洲市场为对象，发展外向型草业经济；建立山前平原、沿黄地区、淮北平原三个精饲料生产、加工基地，生产优质高产饲用玉米，发展精饲料加工业和秸秆加工业。
With the rapid development of the animal husbandry in NCP, shortage of quality forage has become an outstanding factor, which limiting the animal husbandry development in the region. To promote quality forage production is the way to solve the problem. Quality forage has much higher content of protein and lysine than conventional one. Generally, the content of protein in the gramineous is ranged from 13 percent to 15 percent and from 18 percent to 24 percent in the legume. The protein in the forage cultivars can be assimilated more easily by domestic animals. This paper analyzed the characteristics of grass species, which are suitable for growing in CNP and suggested eight growing models. In addition, the development plans of domestic animal grazing industry for different ecological areas were also draw out, which are： establishment of green forage production zone to promote the development of cow grazing; development of two forage export bases in the Haihe river reaches and Yellow river delta to target international forage markets; development of three mainz-for-forage production and processing bases.
