| 摘 要： | 为有效利用当地饲料资源,提高反刍动物配合日粮的利用效率和生产性能,选用西北地区常见的棉籽蛋白、玉米啤酒糟、苹果渣、玉米皮、甜菜粕、菜粕和苜蓿等7种反刍动物常用饲料原料,采用应用滤袋的两级离体消化法对干物质(DM)、有机物(OM)、粗蛋白质(CP)、酸性洗涤纤维(ADF)和中性洗涤纤维(NDF)的体外消化率进行测定。结果表明,甜菜粕的干物质体外消化率(IVDMD)、有机物体外消化率(IVOMD)和粗蛋白质体外消化率(IVCPD)显著高于其他样品(P<0.05),玉米啤酒糟的IVDMD、IVOMD、IVCPD、中性洗涤纤维体外消化率(IVNDFD)和酸性洗涤纤维体外消化率(IVADFD)都处于较低水平。

| Abstract: | In order to use local feed resources effectively and enhance the utilization ratio and production performance of ration formulation.Seven feeds were selected to measure in vitro digestibility of DM,OM,CP,ADF and NDF by two-stage technique using nylon bag.The results showed that the in vitro digestibility of DM,OM and CP in beet pulp was higher than others significantly(P<0.05).The in vitro digestibility of DM,OM,CP,NDF and ADF in maize brewer’s grains was at lower level. |
