摘　　要：粗饲料是反刍动物重要的营养来源,粗饲料的长度是影响反刍动物采食和消化的重要指标之一。适当地调整粗饲料长度,可以发挥其最大的营养价值,并达到优化动物的采食、瘤胃功能及生产性能的作用。文章从粗饲料长度的测定方法以及对反刍动物采食活动、瘤胃消化代谢、生产性能的影响进行论述。Roughage is an important source of nutrition for ruminant. The length is an important indicators to roughage, which affects feed intake and digestion. Proper adjustment of the length of roughage can maximize its nutri- tional value, and achieve the optimization of feed intake, ruminal function and production performance. The measure- ment, the effect of roughage length on ruminant intaking, ruminal digestion and metabolism, and production perfor- mance were discussed in this paper.
