Abstract

The spatial distribution of illuminance and the electric consumption of artificial lighting system is one of the main problems related to broiler production. Therefore, the aim of this study was to evaluate the spatial distribution of luminance level and energy efficiency of different lighting systems for broiler houses. Six types of lamps were tested in two different configurations to find the minimum illuminance of 20 and 5 lux. The tested lamps were incandescent (IL) 100 W, compact fluorescent (CFL) 34 W, mixed (ML) 160 W, sodium vapor (SVL) 70 W, T8 fluorescent tube (T8 FTL) 40 W and T5 fluorescent tube (T5 FTL) 28 W. The first four were evaluated with and without reflective light fixture and the latter two without light fixture. It was observed that the tested system with light fixtures negatively affected the spatial distribution of illuminance inside the house. The systems composed by IL and ML without light fixture led to better results in meeting the minimum illuminance of 20 lux and 5 lux, respectively. T5 FTL presented the lowest energy demand.

Highlights

Lighting is an important environmental factor that affects the production of animals by interfering with their physiological and behavioral responses
Among the systems evaluated to meet the minimum illuminance of 20 lux, the one that best represented the ideal distribution was the incandescent lamp (IL20lux,fa), followed by mixed lamps (ML20lux,fa), T5 fluorescent tube (T5 TFL20lux,fa), compact fluorescent (CFL20lux,fa), sodium vapor (SVL20lux,fa), and T8 fluorescent tube (T8 TFL20lux,fa)
Considering the lighting configurations evaluated, the use of light fixtures provides no benefits for the production of broilers, being detrimental to the distribution of luminance, it should be noted that other configurations can be evaluated
