摘　　要：从整体消化和瘤胃消化的角度出发,研究了复合处理(尿素+石灰)对小麦秸营养价值的影响。结果表明:①复合处理优于尿素处理;②复合处理可使小麦秸的干物质消化率(DM-D)、有机物消化率(OMD)、能量消化率(ED)和中性洗涤纤维消化率(NDFD)分别提高10.8%,21.4%,23.4%,43.8%。In this experiment,digestibility in sheep of wheat straw by urea treat-ment(UT) or urea+lime treatment(ULT) was studied.The resultsshowed:(a) The digestibility of Wheat straw by ULT was higher than thatby UT.(b) DMD,OMD,ED and NDFD of wheat straw by ULT were10.8%,21.4%,23.4% and 43.8% higher than these of nontreatment respec-tively.
