摘 要:利用杂交的方式对甘肃黄鸡与亚发商品蛋鸡杂种的300日龄产蛋量、料蛋比、存活率、淘汰体质量进行了研究。结果表明,黄杂鸡的300日龄产蛋量比甘肃黄鸡提高了 10.33%,料蛋比比甘肃黄鸡低 0.39,存活率比甘肃黄鸡提高了 7. 78%,淘汰体质量接近 2.0 kg。Cross-breeding of Gansu Yellow Chicken and commercial egg breed of Yaffa was conducted and its Yellow hybrid was evaluated in terms of its egg production, feed-egg conversion rate, Survival percentage and culling weight at 300 days of age. The test showed that with a culling weight as nearly 2.0 kg, the Yellow hybrid gave a more egg production and higher survival percentage by 10.33 % and 7.78 % respectively compared to those of Gansu, yellow checken, while its feed-egg conversion rate was 0.39 lower than that of Gansu Yellow chicken.
