This experiment was designed to determine the influence of various white light intensities on spermatogenesis, hematology and growth performance of male quail. A total of 80 birds of one day aged had been assigned to four equal groups: G1 control group was kept under natural light program 12h light:12h dark. G2, G3, G4 were exposed to artificial white light emitting diodes at 0.6, 45 and 25 Lux for 5 hours daily for 8 weeks starting at 14 days of age. The result showed that the application of Lux 0.6, 45 and 25 caused a significant increase in heart weight relative to control. Lux 0.6 led to decrease in total body weight, left testis weight and foam weight. The result revealed that exposure to 0.6 Lux caused significant decrease in sperm count and live sperm percentage and increase in dead sperm percentage. Program of 25 Lux generated a significant increase in RBC counts compared to 0.6 Lux. Exposure to 45 Lux and 25 Lux triggers a significant increase in PCV and hemoglobin concentrations. Exposures to 0.6 Lux and 25 Lux resulted in a significant increase in mean corpuscular hemoglobin concentration, while apply to program 0.6 Lux cause increase in stress index. The best feed conversion ratio was detected in normal daylight, 0.6 Lux and 25 Lux respectively. In conclusion, exposure of male quails to different intensities of white LED bulb had an effect on the some physiological and reproductive parameters.
