摘要
[目的]研究不同光照强度对育雏期蛋鸡啄羽行为和皮肤损伤的影响.[方法]根据不同光照强度,将200只海兰白羽蛋鸡雏鸡分为L1(光照强度为5 lx)、L2(光照强度为10 lx)、L3(光照强度为15 lx)、L4(光照强度为20 lx)4组.第4~6周,观察各组鸡只的啄羽行为,记录被啄鸡只的皮肤损伤,并对皮肤损伤状况进行评分.[结果]被啄鸡只的皮肤损伤部位主要为尾部皮肤(44.02%)、背部皮肤(20.88%)和头部皮肤(15.73%).育雏期蛋鸡的皮肤损伤评分随着光照强度的增加呈增加趋势,但鸡只皮肤仅有轻微损伤.[结论]该研究结果可为在蛋鸡生产中从禽舍光照角度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 injury of laying hens during brooding period.[Method] 200 Hyline white-feather laying chicken were divided into 4 groups(L1,L2,L3,L4)according to light intensity.The light intensity in L1,L2,L3,L4 groups was 5,10,15,20 lx respectively.During the 4th-6th week,the feather-pecking behaviors and skin injury of laying hens in each group were observed and recorded,and the skin injury situations were scored.[Result] The injuryed skin parts of laying hens were mainly tail(44.02%),back(20.88%)and head(15.73%).The skin injury score of laying hens druing brooding period showed an increasing trend with the increase of light intensity.But the injury of skin was little.[Conclusion] The research results can lay the foundation for reducing feather-pecking behaviors from the aspect of light in the chicken shed.
