摘　　要：优质鲁西黄鸡和安卡选育系肉鸡杂交 ,于 70日龄测定正反杂交组合及亲本的体尺、体重及屠体性状 ,结果表明 :F1 杂种在屠体重、屠体率、腿肌重、腿肌率、饲料转化率、出栏率等性状上具有明显的杂种优势 ;配合线性模型分析 。Heterosis for body size, body weight, and carcass characters in LU Xihuang×Anak crosses at 70 days of age were studied. The results showed that heterosis for carcass weight, carcass percentage, leg muscle weight, leg muscle percentage of body weight, feed/body weight and viability were significantly or high significantly different (P<0.05 or 0.01); The cocks'effect values on traits were estimated by the General Linear Model methods.
