Abstract

ABSTRACT Broiler poultry is highly dependent on artificial lightening. Power consumption costs of artificial lighting systems is the second largest expense related to broiler industry, second only to feed expenses. Therefore, the current study focused to analyze technical and economic feasibility of replacing incandescent lamps already used in aviaries with other lamp types. Costs related to power consumption, implementation and maintenance of the lighting systems were evaluated with the aid of financial mathematics using net present value, return over investment and payback. Systems composed of six lamp types were analyzed in two different configurations to meet the minimum illuminance of 5 and 20 lux and for use in conventional sheds and dark house. The lamps tested were incandescent (LI) of 100 W, compact fluorescent (CFL) of 34 W, mixed (ML) 160 W sodium vapor (SVL) of 70 W, tubular fluorescent T8 (TFL T8) of 40 W and tubular fluorescent T5 (TFL T5) of 28 W. For the systems tested, it was found that the tubular fluorescent lamps T8 and T5 showed the best results of technical and economic feasibility.

Highlights

Brazilian poultry production occupies a prominent position on the world stage of meat production
To assess electricity consumption and the costs related to the implementation and maintenance of lighting systems, six types of lamps were tested: incandescent (IL) of 100 W, compact fluorescent (CFLs) of 34 W, mixed (ML) of 160 W, sodium vapor (SVL) of 70W, tubular fluorescent T8 (TFL T8) of 40W and tubular fluorescent T5 (TFL T5) of 28 W
The total costs for implementation of the systems are listed in Table 5, indicating that the incandescent lamp has the highest value, followed by the mixed lamp (ML), compact fluorescent (CFLs), tubular fluorescent T5 (TFLT5), sodium vapor (SVL ) and tubular fluorescent T8

Summary

Introduction

Brazilian poultry production occupies a prominent position on the world stage of meat production. This leadership was achieved thanks to investments in technology, genetic development. Eng. Agríc., Jaboticabal, v.36, n.2, p.242-252, mar./abr. Lighting is one of the environmental factors that interfere with the performance of poultry activity, for houses must be properly lit to reduce cannibalism, bird movement and electricity costs (MENDES et al, 2010). The light does not allow only viewing for birds, but it influences the physiological, reproductive and behavioral activities. Proper lighting manipulation involves the amount of light (time and intensity), light color (or wavelength) and spectral frequency (GONGRUTTANANUN & GUNTAPA, 2012)
