摘　　要：反刍是成年肉羊的一种特殊消化行为,粗饲料的长度可直接影响成年肉羊对其的消化吸收利用。因此,在成年肉羊养殖生产中选择适宜长度的粗饲料进行饲喂对粗饲料的合理化利用及成年肉羊的生产性能具有重要意义。文章对粗饲料长度对成年肉羊采食、瘤胃发育及内环境和生产性能的影响进行综述,旨在为筛选成年肉羊生产中适宜的粗饲料长度提供一定理论参考。Rumination is a special digestive behavior of adult mutton sheep,and the length of roughage intake can directly affect the digestion,absorption and utilization of adult mutton sheep.Therefore,the selection of appropriate roughage length in the production process of adult mutton sheep breeding is of great significance for the rational utilization of roughage and the production performance of adult mutton sheep.In this paper,the effects of roughage type and roughage length on feeding,rumen development,internal environment and production performance of adult mutton sheep were reviewed,aiming to provide a theoretical reference for screening suitable roughage length in adult mutton sheep production.
