摘　　要：　本试验表明,小尾寒羊采食性能好,生长快,饲料报酬高,胴体重、净肉重、眼肌面积三项指标最高,与陕北白绒山羊和黄淮山羊比较差异极显著(P<0.01)。屠宰率比绒山羊组高5个百分点,比黄淮山羊组高3个百分点。平均毛利91.66元,是陕北白绒山羊组(40.4元)的2.3倍,黄淮山羊组的1.5倍,差异极显著(P<0.01)。育肥效果显著优于两个山羊品种,表现出良好的舍饲适应性和产肉性能,且繁殖率极高,是一个较为理想的舍饲养羊母本品种。Experiment result shows: Small tail Han goat has the Characters of good eating function, rapid growth, high reward of feed, heavy body weight, heavy net pork weight, high index of three area of eye muscle. The differences of comparation are obvious (P<0.01) with White Rong goat of north Shaanxi and Huanghuai goat. Its dressing percentage are 5% higher than Rong goat, 3% higher than Huanghuai goat.
