| 摘 要： | 对白来航蛋鸡各阶段体得发育与主要产蛋性状的遗传相关分析表明，６周体重与３００天平均蛋重的跗个关为０．８４１（Ｐ〈０．０１）、与７２周入舍鸡产蛋数的遗传相关为０．６２７（Ｐ〈０．０１）。６周龄前后是培育壮体格、发达内脏的后备母鸡的重要时期。

| Abstract: | According to analysis in genetic correlations,6 week-age body weight was a closely related character for laying performance in laying cycle of egg-laying poultry.rA(xy),coefficient of genetic correlation between average 300 d egg size and it was 0.841(P<0.01),rA(xy) between 72 week-age HH egg yield and it was 0.627(P<0.01).Because of this,it is important that young fowl with strong physique and developed intenals will be cultivated to adopt good nourishment and management during 6 week-age more or less. |
