为了评价紫花苜蓿干草对不同类别辽宁绒山羊的营养价值，研究不同类别绒山羊对各种营养素消化利用能力，开展了本次试验研究。选择成年母羊、育成母羊、成年种公羊、育成公羊和羔羊各4只，依次设为1、2、3、4、5组，只饲喂苜蓿干草。测定不同类别辽宁绒山羊对苜蓿草各营养物质的消化、代谢和利用能力，评价苜蓿草对辽宁绒山羊的营养价值。结果表明，成年母羊对苜蓿草的纤维类和脂肪营养的消化率均高于育成公母羊，而育成公母羊对苜蓿草能量的表观代谢率和利用率均高于成年公母羊。羔羊对苜蓿草能量利用率均低于成年公母羊和育成公、母羊，并与育成公羊差异极显著（P＜0.01）；对苜蓿草钙、磷、纤维类营养、粗蛋白和粗脂肪的表观消化率也低于其他类绒山羊。

Twenty Liaoning Cashmere Goats including four adult ewes, growing ewes, adult rams , growing rams and lambs were divided into group 1, group 2, group 3, group 4 and group 5 accordingly. The digestion, metabolism and utilization ablility of alfalfa in different kinds of Liaoning cashmere goat were de-tected in order to investigate the nutritional value of alfalfa. The result showed that apparent digestibility of CF,NDF,ADF and EE in group 1 were higher than others;the apparent metabolic rate and utilization rate of alfalfa energy in growing rams were higher than adult ewes and rams. The utilization rate of gross energy in lambs were lower than adult ewes and rams, growing ewes and rams, and there was an extremely significant difference in energy utilization rate between group 4 and group 5(P<0.01). The apparent digestibility of Ca, P, CF, NDF, ADF, CP and EE in group 5 were also lower than the other groups..
