摘　　要：对自然放牧和均衡舍饲两种饲养方式下细毛羊体侧部毛丛匀度进行了分析测定,结果显示,全年自然放牧的甘肃高山细毛羊体侧部毛丛匀度较差,各部位细度差异极显著(P<0.01),其中,尖部最粗,与中部和根部差异极显著(P<0.01),中部与根部差异显著(P<0.05);全年均衡舍饲的毛肉兼用细毛羊体侧部毛丛匀度较好,各部位差异不显著(P>0.05)。由此得出,羊毛生长期营养供给的均衡性是影响毛丛匀度的重要因素。Flock uniformity of flank of fine wool sheep were analyzed under two breeding methods including grazing and breeding in shed. The results showed flock uniformity of flank of Gansu high mountain fine sheep under grazing was weak, fiber diameters in all parts were extremely different（ P 〈 0.01 ）. Compared with the middle and the root in fiber, the diameters of top were the largest , and the different were significant（ P 〈 0.05 ）. Flock uniformity of flank of wool -- mutton sheep breeding in shed was right, difference of fiber diameters in all parts were not Significant（ P 〉 0.05 ）. It＇s concluded that nutritional equilibrium during wool growing is vital factor for flock uniformity.
