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)。
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).
