Implantação de iluminação por lâmpadas de LED na produção de frangos de corte

Abstract

The lamp Light Emitting Diode (LED) has been used in the broiler production in Brazil, replacing compact fluorescent (CFL) and features a virtually irreversible trend, as occurred with the introduction of CFL. Despite showing high luminous efficiency and high energy and life, the LED price is still high compared to the CFL, implying higher costs for farmers. There are insufficient data to assess the economic viability of LED lighting in the production of broilers. Thus, this research aims to determine the economic feasibility of using LED in Dark House aviaries. The approach of this research is quantitative, exploratory and descriptive features. In order to achieve the proposed objective, this dissertation is divided into two chapters. In the first chapter, investment alternatives for replacing fluorescent lighting with LED in commercial poultry were presented. Two projects, in order to replace CFL for LED, were developed. The results indicate that the LED generates substantial energy savings in aviaries and it has ideal characteristics for the broilers production. However, the current high price of LED makes the payback period of the investment too long, even without considering the rate of opportunity for the project. The second chapter presents the economic evaluation of LED lighting in the production of broilers, applied to a case study. The energy consumption of two Dark House aviaries, one with CFL and the other with LED, both with the same characteristics as the structure and production capacity, was compared. By deterministic methods of investment analysis, It was evaluated the cash flows, discounted at the cost of a particular opportunity, and the initial cost of the project, determining its indicators. The results indicate economic infeasibility of deployment of the project to replace lighting by LED in Dark House aviary. If the lamp price reduces by approximately 35%, LED lighting can be a viable production of
