从第4周到第6周，将320只海兰白羽蛋鸡雏，按照试验设计采用4个水平随机分组，每组16个重复，每个重复5只鸡，并将其饲养在5、10、15、20lx4个不同的光照强度条件下。观察鸡只的啄羽行为、采食行为、趴卧行为、修饰行为、寻食行为、饮水行为、站立行为和走动行为。试验发现，光照强度对育雏期蛋鸡啄羽的影响很大；随着光照强度的增加，育雏期蛋鸡的啄羽、修饰、寻食、饮水、站立和走动行为呈增加趋势；采食和趴卧行为呈下降趋势。

From the 4th week to the 6th week, 320 Hailan layers were divided into groups at four levels randomly. Each group contained 16 replicates, and each replicate contained five layers. All layers were kept in pens with four different light intensity of 5, 10, 15 and 20lx, and then the feather pecking, feeding groveling, preening, foraging, drinking, standing and walking of them were observed. Results showed that light intensity had significant effects on the feather pecking of laying hens in brooding period; the occurrence of feather pecking, preening, foraging, drinking, standing and walking increased with the increase of light intensity, while the occurrence of feeding and groveling decreased.
