摘　　要：[目的]探究层叠式笼养模式下鸡舍内适宜的光照强度。[方法]以广东温氏某规模化种鸡场密闭笼养黄羽肉种鸡为对象,研究鸡舍内不同光照强度的环境对种鸡产蛋率的影响。[结果]高光照强度组(60~80 lx)在整个试验周期中产蛋率与对照组相比无统计学差异,但在产蛋后期试验组的产蛋率下降趋势更大;低光照强度组(10~20 lx)在产蛋后期的产蛋率明显低于对照组。[结论]光照强度过高或过低均对黄羽肉种鸡的产蛋率有不良影响。[Objectives]In order to study the effects of different light intensity on laying rate of hens in cascade cage mode.[Methods]The effects of different light intensities on egg laying rate of yellowfeathered broiler breeders were studied in a large-scale breeder farm in Wenshi,Guangdong Province.[Results]There was no statistical difference in laying rate in the high light intensity group(60-80 lx)compared with the control group during the whole experiment cycle,but the decreasing trend of laying rate in the experimental group was greater in the late period of laying.The laying rate in the low light intensity group(10-20 lx)was significantly lower than that in the control group in the late laying period.[Conclusions]Too high or too low light intensity has adverse effects on laying rate of yellow-feathered broiler breeders.
