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.
Abstract
[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 9th week to the 11th 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.
