粗饲料粒度对反刍动物体外发酵机制的研究

Study on the effect of roughage size on the fermentation mechanism of ruminants in vitro

我国粗饲料资源丰富,是反刍动物日粮中重要的营养来源。粗饲料的粒度大小可直接影响反刍动物营养消化,适宜的长度能促进反刍动物的咀嚼活动并改善瘤胃发酵功能。因此文章针对粗饲料粒度大小对反刍动物瘤胃发酵特征以及养分消化率方面进行了综述,以期对粗饲料粒度在反刍动物体外发酵机制上的研究提供参考。

China is rich in roughage resources and is an important source of nutrition in ruminant diets. The particle size of roughage is one of the factors that directly affect the nutritional digestion of ruminants. The appropriate length can improve the masticatory activity and rumen fermentation function of ruminants. Therefore, this paper reviewed the effect of roughage size on rumen fermentation characteristics and nutrient digestibility of ruminants, in order to provide reference for the study of roughage size in vitro fermentation mechanism of ruminants.
