【摘要】 研究旨在比较分析金定鸭在笼养和地面平养饲养模式下的生产性能，为评价不同养殖模式下的蛋鸭生产性能提供参考依据。12周龄时，将600羽金定鸭分成2种模式饲养，其中300羽上笼饲养，其余300羽金定鸭为半开放式地面平养。饲养观察测定至72周龄。结果表明，笼养模式下金定鸭的开产日龄132.91 d、43周龄产蛋数149.26枚、72周龄产蛋数321.30枚、总蛋重23.74 kg，均分别优于地面平养模式的开产日龄139.63 d、43周龄产蛋数143.49枚、72周龄产蛋数308.63枚、总蛋重22.43kg；此外，蛋品质测定结果显示，笼养和地面平养的蛋品质没有显著差异。以上结果表明，金定鸭采用笼养模式较平养模式能获得更好的产蛋性能，适宜笼养。更多还原

【Abstract】 The aim of this study is to compare and analyze the production performance of cage rearing and rearing on floor in Jinding ducks, which providing a reference basis for evaluating the production performance of laying ducks under different rearing models. At 12 weeks of age, 600 Jinding ducks were divided into two rearing models, with 300 ducks raised in cages and the remaining 300ducks raised on floor. The observation and measurement of feeding up to 72 weeks old showed that under the cage rearing model, age at the first egg of Jinding ducks was 132.91 d, the egg production at 43 weeks old was 149.26, the egg production at 72 weeks old was 321.30, and the total egg weight was 23.74 kg, all of which were higher than the rearing on floor model’s age at the first egg of 139.63d, the egg production at 43 weeks old was 143.49, the egg production at 72 weeks old was 308.63, and the total egg weight was 22.43kg; In addition, the results of egg quality testing showed no significant difference between cage rearing and rearing on floor. The above results indicate that the cage rearing model of Jinding duck can achieve better egg laying performance than rearing on floor model,which is suitable for cage raising.更多还原
