摘要
中国国民人均营养摄入水平在过去 2 0年中有了显著提高 ,但摄入的动物蛋白还较低 ,随着生活水平的改善 ,国民对肉类食品的需求也从量的需求转到对质的需求 ,加快发展畜牧业是解决这些问题的重要途径 ,但我国面临的精饲料、蛋白饲料、绿色饲料缺乏和饲料总量不足的现实限制了畜牧业的快速发展。讨论了利用我国农区丰富多样的气候资源 ,利用荒山荒坡、地埂、田边地角等土地资源发展蛋白质含量高、生物量大、可多年受益、具有多种效益的木本饲料的重要性、可行性及前景 ,发展木本饲料在经济发展。
Owing to fast economic development and improvement of living standard in China,the requirement for various animal products has greatly increased and changed from quantity to quality.The protein intake, especially animal protein intake in China is quite low. A fast and sustainable livestock development is a prerequisite for improving nutrition intake in China. However, insufficient supply of fodder, especially protein rich fodder, has been the limiting factor for livestock development.Development of woody fodder should be integrated with agricultural land considering the limited rangeland resources and limited land resources in China.It is recommended that various woody fodder trees or shrubs should be planted in various agricultural areas, particularly on land ridges, along land boundaries, and in wastelands, which will contribute greatly to both soil and water conservation and income generation of local people.It is also suggested that eco regional study should be carried out in selection and management options of various woody fodder species.
