摘　　要：研究饲料消化速度是当今家畜饲养业的需要。是以动态学的观点研究饲料在反刍动物瘤胃中停留时间不同被消化的程度。用饲料消化动态评价饲料品质比传统的静态消化率有更重要的意义。在19世纪中叶,已用动物消化试验测定各种饲料的消化率。ABSTRACT Digestible speed and protein degradation rate of several feeds were researched, by hemiartificial rumen technique (i. e. nylon bag method) in this article And so was done feed speed influenced by different degrees of fine feeds. As a result, we acquired their digestible dy- namic pattern of these feeds in bullock rumens, the trend of protein degradation, their feed digestibility being not very influenced by fine degrees of these feeds in a given range and that their degradation rate was relatively stable. This study provides a basic data with evaluating a feed quality according to a viewpoint of kinetics from now on.
