This study was conducted to assess the effects of different monochromatic light sources on broiler live performance and manure emission. A total of 84 30-day-old female broiler chickens were randomly divided in seven different monochromatic light sources: control group (mini incandescent lamps), R-group (700nm, red-LED), Y-group (580nm, yellow-LED), G-group (550nm, green-LED), B-group (470nm, blue-LED), P-group (420nm, purple- LED), W-group (400-760nm, white-LED). Each group has 12 chicks in four replicates of 3 then reared to 80 day. The light intensity was controlled at 30 Lux approximately except for the P-group could only reach 5 Lux, and the light schedule was 12L: 12D. Feed and water were provided for ad libitum. Body weight and manure yield were recorded weekly while the feed and water consumption were recorded daily.
