Resumo: In an attempt to improve thermal environment for high yielding animals, this study was done with animals yielding 40 kg day-1 in the stall-free milk production system to evaluate the air cooling systems with or without forced ventilation. The east-west oriented experimental facility was 65.6 long, 11.1 m wide, 3.5 m from floor to the ceiling, and 2.8 m eaves, with aluminum covered metallic roof, with 11° inclination and small opening in the ridge. The facility was divided into three parts to compose the following treatments: misting; misting + ventilation and the control. Based on the experimental conditions, the environmental results and animal response, misting + ventilation slightly improved yield and comfort conditions.

O galpão experimental, com orientação leste-oeste, possuía 65,60 m de comprimento, 11,10 m de vão, 3,50 m de pé-direito e 2,80 m de beiral, telhado com estrutura metálica, cobertura de alumínio com 11° de inclinação e pequena abertura na cumeeira. O galpão foi dividido em três partes, para abrigar os tratamentos: nebulização, nebulização + ventilação e testemunha. Com base nas condições experimentais, nos resultados ambientais e nas respostas animais, de forma geral, o tratamento nebulização + ventilação foi o que produziu, embora discretamente, as melhores condições de conforto e de produção.Universidade Federal de Viçosa - UFV2010-02-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/17810.13083/reveng.v18i1.196Engineering in Agriculture; Vol. 18 No. 1 (2010); 77-83Revista Engenharia na Agricultura - REVENG; v. 18 n. 1 (2010); 77-832175-68131414-398410.13083/reveng.v18i1reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/178/144Araújo, Handrey Borges deTinôco, Ilda de Fátima FerreiraBaêta, Fernando da CostaSantos, José Humberto TeixeiraSouza, Cecília de Fátimainfo:eu-repo/semantics/openAccess2023-01-19T12:49:28Zoai:ojs.periodicos.ufv.br:article/178Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T12:49:28Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false
