摘　　要：为了研究苹果渣用作反刍动物饲料的饲用价值,以3只安装瘤胃瘘管的陕北白绒山羊母羊为试验动物,采用尼龙袋法测定了苹果渣在陕北白绒山羊瘤胃内的干物质(DM)和粗蛋白质(CP)降解率,并用NRC模型分析了苹果渣的瘤胃降解蛋白(RDP)和瘤胃非降解蛋白(RUP)。结果表明,苹果渣在48h的DM降解率为89.16%,CP降解率为82.89%,且二者之间相关性显著(P<0.01);DM和CP有效降解率分别为61.02%和58.44%;RDP含量为58.52%,说明其蛋白质品质较好。因此,由苹果渣降解特性等可以看出,苹果渣含有较高的营养价值,且适口性好,可用作反刍动物饲料。The trial was conducted to study the nutrition value of apple pomace by NRC method. Ny- lon-bag technique was used to determine the degradation rates and degradabilities of dry matter （DM）, crude protein （CP） of apple pomace. Three Shaanhei white cashmere goats with rumen canula were used to incubating bags, and then the values of RDP and RUP by NRC were analyzed. The results showed that DM and CP disappearance rates of apple pomace at 48 h were 89.16% and 82.89%, moreover, the DM disappearance rates of apple pomace had significant correlation with the CP disappearance rates （P〈0.01）. Effective degradation rates of DM and CP were 61.02% and 58.44%, respectively, and the RDP was 58.52%. Hence, apple pomaee can be used as ruminant animal feed due to its higher nutrition value and good palatability.
