试验探讨了通过导入体大高产澳血公羊对甘肃高山细毛羊 F1、F2代周岁母羊主要生产性能的影响。从体侧毛长、体重、剪毛量、纤维直径、净毛率等主要生产性能进行了分析比较，为培育甘肃高山细毛羊体大高产品系奠定基础。结果表明：（1）F1代周岁母羊与同龄甘肃高山细毛羊超细品系母羊相比，羊毛长度增长了0．398 cm（P＜0．01），体重增加了3．7949 kg（P＜0．01），剪毛量有所增加（P＜0．01），毛纤维变粗（P＜0．01），净毛率没有变化。（2）F2代周岁母羊羊毛细度变化不显明，与甘肃高山细毛羊超细品系母羊相比变粗了1．294μm（P＜0．01）；毛长和剪毛量有所提高（P＜0．01）；体重分别较甘肃高山细毛羊和甘肃高山细毛羊超细品系母羊增加了3．3051 kg（P＜0．01）、1．0648 kg（P＜0．05）；净毛率没有变化（P＞0．05）。

the study investigated the effect of the introduced Australian-blood ram on the production performance of F1 and F2 one-year old GAM and compared the production indexes inxluding side-body wool lengthm weight ,shearing quantity ,fiber diameter and scouring yield to prepare for breeding bigger and high-yield CGAM .The results showed that compared with GAM and CGAM ,F1 hybrid increased the wool length by 0 .398 cm(P< 0 .01) ,weight by 3 .7949 kg (P< 0 .01) ,shearing quantity and fiber diameter increased(P< 0 .01) ,and the scouring yield kept unchanged .F2 hybrids had similar diameter with GAM , and increased it compared with CGAM by 1 .294 μm ( P < 0 .01) ,wool length and shearing quantity in-creased (P< 0 .01) ,though slightly (P> 0 .05) ;body weight increased by 3 .3051 kg and 1 .0648 kg rep-spectively ,and the scouring yield kept the same .
