[目的]研究不同饲养密度对育雏期蛋鸡啄羽行为和皮肤损伤的影响.[方法]根据不同饲养密度,将200只海兰白羽蛋鸡雏鸡分为4组,研究不同饲养密度对育雏期蛋鸡啄羽行为和皮肤损伤的影响.[结果]被啄鸡只的身体皮肤损伤部位主要是尾部皮肤(39.17%)、背部皮肤(21.66%)和头部皮肤(20.45%).育雏期蛋鸡的皮肤损伤评分总分随着饲养密度的增加呈增加趋势,而鸡只的身体只是轻微损伤.[结论]研究结果可为降低蛋鸡啄羽行为的发生率奠定基础.%[Objective]To study the effects of different stocking density on the feather-pecking behavior and skin damage of laying hens during brooding period.[Method]200 Hyline white-feather laying hens were randomly divided into 4 groups according to different stocking density.The effects of different stocking density on the feather-pecking behavior and skin damage of laying hens during brooding period were studied.[Result]The main skin-damaged parts of laying hens pecked were tail(39.17%),back(21.66%)and head(20.45%).The total score of skin damage of laying hens during brooding period increased with the rise of stocking density.But the damage of skin was little.[Conclusion]The research results can lay the foundation for decreasing the incidence of feather-pecking behavior.
