摘要
对白来航蛋鸡各阶段体重发育与主要产蛋性状的遗传相关分析表明 ,6周体重与300d平均蛋重的遗传相关为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周龄前后是培育硕壮体格。
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.
