RESUMO

ABSTRACT Light is important for the physiology and zootechnical development of broilers and is characterized by the type of source defined by the spectral emission and geometry of the lamp, as well as the intensity and spatial distribution of the illuminance. The aim of this study was to verify the influence of an artificial lighting system based on tubular Light Emitting Diode (LED) lamps on the productive performance of broilers. The study was carried out in two broiler houses located in Londrina-PR. The lighting system for one of the broiler houses was composed of 52 tubular LED bulbs of 18 W powers, and the control broiler house consisted of 75 incandescent bulbs with 60 W powers. This research was divided into two parts; the first phase was evaluated the environmental similarity (dry bulb temperature, air velocity, and illuminance) between the two broiler houses. The second was based on the zootechnical indexes: average body weight, feed intake, feed conversion and mortality. Only the illuminance variable differed statistically. The lighting system based on the use of a tubular LED lamp, with fewer points of illumination and more distant positioning between lamps and lower power installed, did not compromise the zootechnical performance.
