Effects of Different LED Light Colors on Growth Performance,Comb Development and Feather Pecking Behavior of Xueshan Chicken

[目的]研究不同LED光色对雪山鸡生长性能、鸡冠发育和啄羽行为的影响。[方法]试验采用LED暖红灯、蓝绿灯和暖黄灯对46日龄雪山鸡进行24 h照明,持续35 d,然后测定鸡群的生长性能、鸡冠发育和啄羽情况。[结果]不同光色下3组雪山鸡的体重无显著差异(P>0.05);蓝绿组雪山鸡的冠高显著大于暖红组和暖黄组(P<0.05);3组雪山鸡的冠长差异不显著(P>0.05);3组雪山鸡的鸡冠红度评价差异不大;蓝绿组雪山鸡的啄羽比例远低于暖红组和暖黄组。[结论]LED蓝绿灯可在雪山鸡饲养中推广应用。

[Objective] The aim was to study the effects of different light colors on growth performance,comb development and feather pecking behavior of Xueshan Chicken. [Method]Using the warm-red light,blue-green light and warm-yellow light,the 46 day-old chickens were shined by 24 hours of lighting for 35 days,and the growth performance,comb development and feather pecking behavior were measured. [Result]Under the different LED light colors,weight of Xueshan Chickens was not significantly different among three groups（ P 0. 05）; the crown height of blue-green groups was significantly greater than warm-red groups and warm-yellow groups（ P 0. 05）; the crown length was not significantly different（ P 0. 05）; red degree of comb was not significantly different; the ratio of feather pecking of blue-green groups was much lower than warm-red groups and warm-yellow groups. [Conclusion] LED blue-green light can be used in Xueshan Chicken raising.
