摘要
试验用尼龙袋法测定了35kg滩羊采食混合牧草和配合饲料中干物质(DM)、粗蛋白(CP)、酸性洗涤纤维(ADF)和中性洗涤纤维(NDF)在瘤胃内6h、12h、24h、36h、48h和72h的降解率。结果表明:混合牧草中CP降解率比配合饲料高出7.96个百分点,而配合饲料中DM、ADF和NDF降解率分别比混合牧草高出0.87、11.92和12.15个百分点。因此,牧区养羊时放牧与舍饲结合,两种饲料可得以互补,使有限的资源可以得到最大的合理利用,降低生产成本。
The expartment was conducted to determine the degradation rate of the dry matter (DM),crude protein (CP),neutral detergent fiber (NDF) and acid detergent fiber (ADF) about compound feed and mixed pausture eaten by 35kg tan-sheep in rumen at 6h,12h,24h,36h,48h,and 72h with nylon bags of law. The result indicates the degraing rate of crude protein (CP) about mixed pasture is 7 higher 7.96% than the compound feed but DM,ADF,NDF respectively lower 0.87%、11.92% and 12.15% than the formula feed . so graze and feed in the shed shoud be combined in the pastoral area,two kinds of fodder are complementary and can let limited fodder resources get the greatest rational utilization,at the same time,degrading the production cost.
