Resumo: | In present research the potential use of evaporative cooling systems (ECS) associated to tunnel ventilation system (TVS) for broiler reared in Southeastern Brazil was studied. Four configuration systems were tested: (a) TVS, (b) TVS associated to a pad cooling system with 40% efficiency (TVSPAD40), (c) TVS associated to a pad cooling system with 70% efficiency (TVSPAD70) and (d) TVSPAD70 associated to a misting system (TVSPAD70+MIST). Thermal environment was characterized by temperature-humidity index, and the chicken performance was estimated by daily feed intake, daily weight gain and feed conversion. Climatic data from 1980 to 2001, released through Reanalysis-2 Project from NCEP/NCAR were used in this research. The benefitial effect of the use of ECS with TVSPAD70+MIST for providing better production condition was verified, especially during September and October for almost all the southeastern region, mainly in northern and northwestern part of the Minas Gerais State. |

Quatro configurações do sistema foram testadas: a) SVT; b) SVT associado à SRE do tipo material poroso umedecido com 40% de eficiência (SVTPAD40); c) SVT associado à SRE do tipo material poroso umedecido com 70% de eficiência (SVTPAD70) e d) SVTPAD70 associado a sistema de nebulização (SVTPAD70+NEB). O ambiente térmico foi caracterizado por meio do índice de temperatura e umidade, enquanto o desempenho das aves foi determinado pelo consumo de ração diário, ganho de peso diário e conversão alimentar. Dados meteorológicos de 1980 a 2001, disponibilizados pelo Projeto Reanálise-2 do NCEP/NCAR, foram utilizados nesta pesquisa. Verificou-se o efeito benéfico do uso dos SRE, com SVTPAD70+NEB proporcionando as melhores condições de produção, em especial nos meses de setembro e outubro para quase toda a região Sudeste, com destaque para as mesorregiões Norte e Noroeste de Minas Gerais.Universidade Federal de Campina Grande2019-11-20T10:39:41Z2019-11-20T10:39:41Z2009info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfCARVALHO, V.
