摘　　要：选用3只安装有永久性瘤胃瘘管的绵羊,采用尼龙袋法对不同配比的番茄酱渣与苜蓿、棉壳制成的草颗粒在瘤胃2、6、12、24、36和72h的降解率进行研究,从而确定了番茄酱渣与苜蓿、棉壳合适的制草颗粒配比和混合草颗粒中各营养成分的动态降解率。结果表明,番茄酱渣∶苜蓿∶棉壳为60∶35∶5时正组合效应最高,该组降解率:dp(DM)=27+40.9×(1-e-0.0139t)(n=6,R2=0.978);dp(CP)=31.9+32.6×(1-e-0.071t)(n=6,R2=0.986);dp(NDF)=14.3+56.1×(1-e-0.023t)(n=6,R2=0.994)。Three rumen-cannulated sheep were used to measure ruminal degradation, using the nylon bags method for different ratio of tomato sauce residue and alfalfa, cotton shell particles made of grass in the rumen degradation rare of 2,6,12,24,36 and 72 h,which studied to determine the tomato sauce residue and alfalfa, cotton grass system shell particles suitable ratio, mixed grass particle dynamics of nutrients in the degradation rate. The results showed that tomato sauce residue∶alfalfa∶cotton shell was 60∶35∶5,which was the highest combination of effects.Degradation rate of the group：dp（DM）= 27＋40.9×（1-e^-0.0139t）（n=6,R2=0.978）;dp（CP）=31.9＋32.6×（1-e^-0.071t）（n=6,R^2=0.986） ;dp（NDF）=14.3＋56.1×（1-e^-0.023t）（n=6,R^2=0.994）.
