| 摘 要： | 测定选育后的狼山鸡（N系）快、慢羽5，10，15和20周龄的生长体重和产蛋性能（开产日龄、开产体重、65周产蛋量、蛋重），结果两个品系间差异均不显著。仅快羽系1-42日龄育雏成活率明显高于慢羽系。

| Abstract: | The influence of sex-linked feather-growth-rated genes on production performance was evaluated after fast-growth-feathered and low-growth-feathered strains of langsan chicken was developed.The results indicated that there was no significant difference in growth weight of different week of age(5,10,15and20week of age)and lying perfor-mance(the day of laying first egg,the weight of laying first egg,total egg prodution and total egg weight in65th week)between both strains.Only viability in1to42days of age in fast-growth-feathered strain was higher than that in low-growth-feather strain. |
