摘　　要：枯草期选甘肃高山细毛羊成年母羊180只,后备母羊38只,羔羊40只,进行为期171 d的放牧与舍饲对比试验。结果表明:试验组(暖棚舍饲)平均每只成年母羊、后备母羊和羔羊体质量分别增加5.1、9.8和6.9 kg,增幅为:11.72%、30.81%和32.86%;对照组(放牧)每只成年母羊、后备母羊和羔羊体质量分别平均下降7.3、5.0和1.0 kg;试验末,试验组成年母羊和后备母羊体质量极显著高于对照组(P<0.01),试验组羔羊体质量显著高于对照组(P<0.05)。羊毛长度试验组成年母羊、后备母羊和羔羊羊毛每只分别平均增长3.9、3.8和2.7 cm,试验组成年母羊和后备母羊比对照组提高10.4%和16.0%,羔羊比对照组降低11.2%,试验组和对照组差异不显著(P>0.05)。试验组各年龄段产羊毛量分别达5.24、4.56和3.79 kg,比对照组分别提高60.24%、73.38%和49.80%,差异极显著(P<0.01)。试验组纯收入分别为成年母羊5.35元/只,后备母羊45.65元/只,羔羊59.57元/只,对照组由于掉膘损失严重,成年母羊和后备母羊分别损失28.32和13.05元/只,羔羊收益29.3元/只。One hundred and eighty Gansu Alpine fine wool sheep ewes,38 replacement ewes and 40 lambs were selected from the farmers in Sunan Yugur autonomous County,divided into two groups randomly and the sheep of experimental group were pen fed in greenhouse,the control group were grazing as traditional from December 30 th 2008 to May 26 th 2009.The results indicated the body weight gain of adult ewes,replacement ewes and lambs of experimental group are 5.1,9.8 kg and 6.9 kg;the body weight lose of adult ewes,replacement ewes and lambs of control group are 7.3,5.0 and 1.0 kg,the average adult ewes and replacement ewes body weight gain of experimental group were significantly higher（P〈0.01）than the control group at the end of experiment,lambs of experimental group was higher（P〈0.05） than control group.The average fleece length increase of experimental group and control group was not different（P〉0.05）.The wool productivity of adult ewes,replacement ewes and lambs of experimental group were 5.24 kg,4.56 kg and 3.79 kg,which were more（P〈0.01） than the control group by 60.24%、73.38% and 49.80%.The net income of adult ewes,replacement ewes and lambs of experimental group are 5.35 RMB,45.65 RMB and 59.57 RMB,and the lamb of control group was 29.3 RMB.The adult ewes and replacement ewes of control group were lost 28.32 RMB and 13.05 RMB.The net income of experimental group was more（P〈0.01） than control group.
