摘　　要：[目的]研究不同光照强度对育成期蛋鸡啄羽行为和皮肤损伤的影响。[方法]第9~11周,将150只海兰白羽蛋鸡随机分为2组,分别饲养在光照强度为5和15 lx的鸡舍。观察试验鸡只的啄羽行为,同时记录被啄鸡只的身体皮肤部位,并对皮肤损伤状况进行评分。[结果]被啄鸡只的身体皮肤损伤部位主要是尾部皮肤(37.54%)、背部皮肤(20.64%)和头部皮肤(16.91%)。育成期蛋鸡的皮肤损伤评分总分随着光照强度的增加呈增加趋势,鸡只的身体只是轻微损伤。[结论]研究结果可为在蛋鸡生产中减少啄羽行为提供参考。[Objective] To study the effects of different light intensity on feather-pecking behavior and skin damage of laying hens during finishing period.[Method]From the 9-（th）week to the 11-（th）week,150 Hyline white-feather layers were randomly divided into two groups. They were fed in henhouse with two different light intensity（ 5,15 lx）. Feather-pecking behaviours were observed,and skin parts of pecked laying hens were recorded,and the skin damage were scored.[Result] When feather pecking occurred,the main skin parts of body pecked by laying hens were mainly tail（ 37. 54%）,back（ 20. 64%） and head（ 16. 91%）. The total score of damaged skin of laying hens was increased with the increase of light intensity. But the damage of skin was little.[Conclusion]The research results can provide references for reducing feather-pecking behaviors in the production of layig hens.
