摘要
测量了黑凤鸡种蛋的蛋重和蛋形指数 ,研究蛋重和蛋形指数对黑凤鸡种蛋孵化率的影响。结果表明 :黑凤鸡种蛋蛋重在 3 6 8～ 46 9g ,蛋形指数在 0 675～ 0 789孵化率较高。
The egg size and index of egg shape were measured to study the effect of egg size and index of egg shape on the hatchability of breeder egg of Heifeng hen.The results showed that there was better hatchabiliey of breeder egg when the egg size was 36.8～46.9g and the index of egg shape was 0.675～0.789. \ \
