摘要

本试验旨在研究多层传统电箱饲养的商品蛋鸡的乳房状况和龙骨偏差对峰后产蛋量的影响。首先，根据龙骨偏差的存在，将鸟类分为两组。然后根据乳房发育良好和相对发育良好的情况将鸟类进一步分为两组。试验期间蛋鸡饲养在与商品蛋鸡相同的管理条件下。在62 ~ 77周龄期间收集各组日产蛋量、采食量、死亡率和蛋重数据。龙骨偏差对蛋鸡体重和蛋重无显著影响。不同乳腺状况组间雏鸟的初始和最终体重差异显著(P

Effects of keel bone deviation on post-peak egg production in a commercial laying hen flock with different breast condition

This study was made to investigate the effects of breast condition and keel bone deviations on post-peak egg production of a commercial laying hen housed in a multi-tier conventional battery cage. The birds divided into two groups according to presence of keel bone deviation at first. Then the birds further divided into two groups according to breast condition as well developed or relatively well developed. The laying hens were kept under identical management conditions for commercial laying hens during the study. Data about daily egg production, feed intake, mortality and egg weight was collected from 62 to 77 weeks of age in the groups. There were no significant effects of keel bone deviation on body weight and egg weight of the layer hens. The initial and final body weight of the birds are significantly different between the breast condition groups (P
