| 摘 要： | 按照开产日龄将120只缙云麻鸭（母鸭）分为10个组（组距3d），比较各组鸭的300d总蛋数、300d总蛋重及平均蛋重。结果表明，第3组（94～96d）的300d总产蛋重显著高于第1组（88-90d）（P〈0．05），但其他组别之间均无显著差异（P≥0．05）；10个组别的300d总产蛋数和平均蛋重也均无显著差异（P≥0．05）。

| Abstract: | To compare the total number, weight and average weight of the eggs laid during a period of 300 days, Jinyun ducks were divided to ten groups based on their first egg ages. The results indicate：the total weight of the eggs of the third group （94-96d） was significantly higher than that of the first group （88-90d） （P〈0.05）; no significant difference existed among other groups （P≥0.05）; the difference in the total number and average weight of the eggs of the ten groups was not significant either （P≥0.05）. |
