In order to investigate the best lighting condition for chicken raising, 1440 Jinmao Broilers were divided into 10 groups with 10 kinds of monochromatic lighting conditions to compare the effects of different light colors on the growth performance, feather picking and comb size of broilers. Moreover, 210 Jinmao breeders were divided into 7 groups with long-wave band of visible light. The spectral irradiance of each group was adjusted to the same value. After several weeks, male broilers in 400–540 nm and female broilers in 540–660 nm grew faster than other groups. Breeders exposed to light of 740 nm had better performance in egg laying.
