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

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(P0.05);蓝绿组雪山鸡的冠高显著大于暖红组和暖黄组(P0.05);3组雪山鸡的冠长差异不显著(P0.05);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。

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

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] Un-der 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 dif-ferent(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 .
