摘　　要：试验以高压快速氨化稻草为主要粗饲料,研究不同粗饲配比的TMR日粮对羔羊生产性能的影响。结果表明在羔羊粗饲料中增加氨化稻草的比例可以提高羔羊的采食量、日增重,并提高瘤胃中DM、NDF、CP的消失率。但是要想获得最佳饲喂效果,需在保持适当氮能比,从试验结果来看氨化稻草和青贮玉米配比为7∶3时效果更佳。In this experiment,rapid ammoniated rice straw was used as the main roughage of TMR diet to study the effects of different forage proportion of diets on lambs.The results showed that feed intake,daily weight gain and DMD,NDFD,CPD in rumen increased with the proportion of ammoniated straw in forage.But a suitable C/P is required to get the best FCR.In this experiment,ammoniated straw accounting for 70% of forage was much better.
