摘要
限制反刍家畜实现对饲料高效利用和畜产品最大产出的主要因素是必需氨基酸,这些氨基酸必须由瘤胃降解蛋白为原料合成的菌体蛋白和瘤胃非降解蛋白从小肠供给。家畜才能实现肉奶皮毛等畜产品的最大产出。应用瘤胃降解蛋白和瘤胃非降解蛋白这一体系评价反刍家畜的蛋白质营养需要和饲料的蛋白质质量比粗蛋白更准确,更经济、更能满足家畜高产的需求。
It is essential amino ailds that are a main factor limiting ruminants to utilize feed efficiently and to give maxi- mum production.Only when essectial amino acids are supplyed from undegraded and bacterial protein in small intes- tine which is converted by degraded protein in rumen,can ruminants give maximum production for meat,milk,hide and wool. To use this new system of degraded and undegraded protein in runcen to appraise protein requirements for rumi- nants and quality for feed,it is more accurate,more economy and als.Can meet requirements better for maximum production.
