摘　　要：本试验设计了2个地方黄羽肉鸡品种与隐性白羽肉鸡的杂交组合,测定比较了不同周龄的体重和屠体性状。实验结果表明,地方品种与隐性白羽肉鸡的杂交后代生长速度极显著高于地方品种纯繁后代;石歧杂和北京油鸡与隐性白羽肉鸡杂交后代间生长速度无显著差异,且北京油鸡比石歧杂表现更强的杂种优势;杂交及纯繁后代在屠体性状上有一定的差异。Two kinds of cross combinations were designed in this experiment with Siqiza,Beijingyou and recessive white feather broilers.Body weights and body composition traits in different weeks were analysed The results showed that body weights of offsprings were significant higher than that of pure breeding offsprings of native breeds.There was no significant difference in body weight of early stage of growth between the cross offsprings of Siqiza and recessive white feath er broilers and Beijingyou and recessive white feather broilers.Heterosis of Beijingyou was greater than Siqiza.There was some difference between cross and pure line on the body composition traits.
