摘　　要：[目的]为合理利用秸秆资源，发展养驴业提供科学依据。[方法]以3头3-4岁雄性疆岳驴为试验动物，采用全收粪消化试验研究400g/d精料水平下疆岳驴对麦秸、稻草、玉米秸秆和青贮日粮的利用率。[结果]疆岳驴对青贮日粮干物质、有机物、NDF、ADF和能量的采食量分别为（2 909.08± 208.65）g/d、（2 565.20±166.25）g/d、（1 640.96±216.36）g/d、（1 036.48±138.23）g/d、（50.88±3.62）MJ/d，均低于其他3组，而对青贮日粮中这几种物质的消化率分别为（59.10±4.62）%、（64.20±4.03）%、（60.71±4.25）%、（52.79±5.13）%、（61.92±4.32）%，均高于其他3组；疆岳驴对麦秸、稻草和玉米秸秆干物质的采食量无显著差异，对麦秸、稻草中NDF、ADF、有机物和能量的消化率均低于玉米秸秆。[结论]疆岳驴对青贮日粮和玉米秸秆的利用率较高。[ Objective ] The aim was to provide the scientific basis for the reasonable utilization of straw resource and the development of donkey raising. [ Method ] With 3 male Jiangyue donkeys that 3 -4 years old as the tested animals, through digestion trial experiment with totai collecting feces method, the utilization rates of Jiangyue donkey on rice straw, wheat straw, corn stalk and silage diet under the condition of 400g/d concentrate were studied. [ Result ] The feed intakes of Jiangyue donkey on dry matter, organic matter, NDF, ADF and energy in silage diet were （2 909.08 ± 208.65） g/d, （2 565.20 ± 166.25 ） g/d, （ 1 640.96 ±216.36 ） g/d, （ 1 036.48 ±138.23 ） g/d, （50.88± 3.62） MJ/d resp. , being lower than those of other 3 groups, and the digestibility of Jiangyue donkey on those matters were （59. 10 ±4. 62）% 、（64.20 ±4.03）% , （60.71 ±4.25）% , （52.79 ±5.13）% , （61.92 ±4.32）% resp. , being higher than those of other 3 groups. The feed intake of Jiangyue donkey on wheat straw, rice straw and corn straw had no difference, and the digestibility of Jiangyue donkey on NDF, ADF, organic matter and energy in wheat straw and rice straw were lower than those in corn straw. [ Conclusion] The utilization rate of Jiangyue donkey on silage diet and corn straw were higher.
