Slaughter Experiment of Oular Sheep and Gannan Valley-type Tibetan Sheep

通过对欧山F1和山谷型藏羊羔羊进行屠宰试验,结果得出:9月龄欧山F1羔羊宰前平均活重为38.25 kg,比本地山谷型藏羊羔羊宰前平均活重高10.17 kg,差异极显著(P<0.01)。欧山F1羔羊胴体重和屠宰率分别为15.14 kg和39.58%,比对照组高4.58 kg(P<0.01)和1.96个百分点,差异极显著。欧山F1羔羊净肉率、后腿比例和腰肉比例分别为29.65%、38.18%和12.99%,高于山谷型藏羊4.01、7.78和2.68个百分点;欧山F1羔羊GR值和眼肌面积分别为8.23 mm和12.74 cm2,高于山谷型藏羊1.48 mm和4.38 cm2。
