Abstract
Growth performance, behavior, and development of broilers reared under red, green, and blue monochromatic and/or multicolor LED-based illuminants is investigated. The lighting treatments were performed on a 24h lighting basis during six weeks. Monochromatic red(630 nm), green(520 nm), and blue(460 nm), and simultaneous blue-green, and whitelight housing illumination was employed. Bodyweight, food consumption, and behavior were monitored and compared amongst light treatments. The behavioral data showed that broilers reared under green lighting presented the lowest respiratory rate (87 mov. min-1) while those under red lighting presented the highest (96 mov. min-1). Results also showed that broilers under blue and/or green monochromatic illumination exhibited up to 6%, and 8.9 % increase in final bodyweight when compared to those under red or white-light, respectively. The highest feed intake, and lowest body weight gain was observed in broilers reared under blue and red illumination, respectively.
