摘　　要：本试验通过尼龙袋法研究了杏渣在绵羊瘤胃内干物质、粗蛋白、中性洗涤纤维、酸性洗涤纤维和有机物的降解特性。结果表明:杏渣中营养物质在绵羊瘤胃中的降解率均随瘤胃中滞留时间的延长呈现增高的趋势,杏渣中DM、CP、NDF、ADF和OM的有效降率分别为80.75%、65.44%、32.98%、41.37%和79.55%。In this study, the degradation properties of dry matter （DM）, crude protein （CP）, neutral detergent fiber（NDF）, acid detergent fiber（ADF）, and organic matter（OM） of apricot dregs in sheep rumen were studied by the nylon bag method. The results showed that nutrient degradability of apricot dregs in rumen were increased with digestion time rising. The effective degradable rates of DM, CP, NDF, ADF and OM were 80.75%, 65.44%, 32.98%, 41.37%, and 79.55%,respectively.
