| 摘 要： | 对仙湖肉鸭第13世代A系核心群60个家系360只母鸭和B系核心群48个家系288只母鸭的产蛋性能进行观测、记录，并统计分析。结果显示：A系种鸭平均开产日龄比B系稍迟，平均开产体重比B系大，开产蛋重则比B系轻，但A、B两系这三个指标均差异不显著；B系种鸭的繁殖性能明显优于A系种鸭，其50周龄、64周龄产蛋数、种蛋受精率、受精蛋孵化率均比A系高，且差异极显著；B系种鸭每个月的产蛋率要比A系高5～10个百分点。

| Abstract: | The laying performance of 360 female ducks from 60 families of core group A and 288 ducks from 48 families of core group B in the 13th generation of Xianhu meat Ducks were observed, recorded and analyzed. The results showed that the average age of producing first egg of female ducks of group A was later than that of group B, and the average weight of producing first egg of female ducks of group A was less than that of group B. However, the differences were not significant. Compared with the female ducks from group A, the average reproduction performance from that of group B were much more excellent. The egg numbers, egg fertility rate and hatchability of fertile eggs of female ducks from group B were much higher than that of female ducks from group A in 50 W and 60 W （P 〈 0.05）. The monthly laying rate of female ducks from group B were 5% to 10% higher than that from group A. |
