Poultry management is associated with light due to positive effects of photoreceptors on animal’s growth, immunity and homeostasis. Colors influence the efficiency of poultry performance and behavior. Light-emitting diode (LED) can use for providing monochromatic light source. In this trial, two hundred Ross 308 broiler chicks were studied in four different light groups as follows; White (Control), Red (RL), green (GL) and blue (BL) during 42 trial days. At the end of the study, the serum Superoxide dismutase (SOD), Catalase (CAT), Glutathione Peroxidase (GPx) and malondialdehyde (MDA) enzyme activities were measured to evaluate the oxidant-antioxidant balance. The oxidant marker MDA was found the highest value in group RL (p:0.0001 ; 9.24±0.33). On the other hand, in group GL, all antioxidant parameters were found the highest value (p<0.05).  Also, SOD and GPx values were increased in group GL (SOD: 150.61±9.14 ; GPx: 186.96±10.50)  than BL (SOD: 139.29±5.19 ; GPx: 160.02±3.15) statistically (p<0.05). The results showed that red light may be a stressor, and on the contrary, green light may be a positive monochromatic color for growth, oxidant-antioxidant balance and homeostasis for broilers.
