摘要
将乌骨鸡种蛋按蛋形指数分为A(≤ 72 0 % )、B(72 1 %～ 74 0 % )、C (74 1 %～ 76 0 % )、D (76 1 %～78 0 % )、E(≥ 78 1 % )五组进行孵化 ,结果表明 :五组乌骨鸡的受精蛋孵化率分别为 82 6 %、86 1 %、90 2 %、87 2 %、82 5 % ,C组显著高于A、B、D、E各组 (P <0 0 5 ) ,并极显著地高于A组和E组 (P <0 0 1 ) ,蛋形指数为 74 1 %～ 76 0 %的乌骨鸡种蛋孵化效果最佳。
The breeding eggs of silk fowl were divided into five teams A(≤72 0%)、B(72 1%～74 0%)、C(74 1%～76 0%)、D(76 1%～78 0%)、E(≥78 1%) to hatch according to egg shape index The results showed that fertile eggs hatch rates of the five teams are 82 6%、86 1%、90 2%、87 2% and 82 5% respectively,and the hatch rate of C team in higher than those of A、B、D、E teams (P<0 05) and A、E teams (P<0 01) The hatching effect of breeding eggs whose egg shape indexes are among 74 1%～76 0% is the best
