Abstract :The objective of the current study was to determine the effects of monochromatic lighting on female broiler performance for 42 d rearing period. 480 female broiler chicks insert ignore into journalissuearticles values(Ross-308); were divided into three lighting treatment groups in four replicates each. All birds were housed three independent rooms previously divided by wooden bars into 12 sealed cells of 4 m2 insert ignore into journalissuearticles values(40 chicks each one);. Average light intensity was 10 lux for all groups. A 23-h photoperiod was provided for first 7 d, followed by an 18- h photoperiod through to 42 d. Lighting treatments were: 1- control daylight insert ignore into journalissuearticles values(mini incandescent light bulbs for 42 days);; 2- 560 nm Green LED insert ignore into journalissuearticles values(G); for first 3 wks and 480 nm Blue LED lamps insert ignore into journalissuearticles values(B); lamps for remaining 3 weeks; named G-B group and last group; 3- G for first 3 wks and G-B mix for remaining 3 weeks; named G-GB MIX group. At weekly intervals, mortality, body weight insert ignore into journalissuearticles values(BW);, live weight gain insert ignore into journalissuearticles values(LWG); and feed consump-tion insert ignore into journalissuearticles values(FC); was recorded on group basis. A significant increase in BW, LWG and FC was observed in broilers reared under G-B and G-GB mix lighting compared to control group. G-B and G-GB mix significantly increased carcass weight compared to control group. We suggest that green light from hatching to 21 d of rearing period and switching it to blue or green-blue mix emitted from monochromatic insert ignore into journalissuearticles values(LED); lamps beneficially influence performance traits of female broilers.
