Led Tubs Artificial Lighting System in Broiler Production

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.

Poultry Farming and Lighting: A Review on the Importance of Lighting in Broiler Chicken Aviaries

“…Broiler chicken are considered a photosensitive, thus their behavior and well-being are affected and influenced by environmental lighting. This perception of light occurs through the retina, located in the bird's eyeball, forming images and differentiating colors, allowing interaction between the bird and the environment, potentially affecting their behavior and growth (Seber et al, 2018).…”

“…The use of LED lamps, or light-emitting diode lamps, presents an energy-saving opportunity, making the process and improvement of the sector viable. Concerning the advantages of using LEDs compared to fluorescent and incandescent lamps, studies point out better energy efficiency, longer lifespan, resistance to humidity, and the availability of choice in supplying certain wavelengths throughout the breeding cycle, besides a lower dimming cost (Seber et al, 2018).…”

“…Light Emitting Diode (LED) lamps are more economical than fluorescent and incandescent lamps, one of the reasons is improved energy efficiency, a superior lifespan, more options regarding lamp characteristics, and easy dimmability (Seber et al, 2018).…”
