Resumo: The handling of the thermal environment in the initial phase of commercial broiler chicken production is fundamental for the zootechnic performance of fowls. This study was done to analyze the thermal environmental comfort and the zootechnic performance of broiler chickens grown in two different half-acclimatized ventilation systems: one with negative pressure and the other with positive pressure, during two complete cycles under winter conditions on southern Brazil. Based on the results of the environmental variables, it could be noticed that, on the first week of life, the temperature averages were below the zone which corresponds to the animal thermal comfort zone, and, the air humidity measurements between 65 and 70% for both treatments, required levels for the poultry comfort. In relation to the poultry productive performance indexes, it was found that all were within the range considered as desirable, relative to the average values obtained by the Brazilian broiler chicken production.

Neste trabalho, objetivou-se avaliar o conforto térmico do ambiente e o desempenho zootécnico de frangos de corte, criados em dois diferentes sistemas de ventilação: com pressão negativa e com pressão positiva, durante dois ciclos completos de produção, em condições de inverno, na região sul do Brasil. Com base nos resultados das variáveis ambientais, observou-se que, na primeira semana de vida, as médias de temperaturas estiveram abaixo da faixa correspondente ao conforto térmico por animal, e, para a umidade relativa do ar entre 65 e 70% para ambos os tratamentos. Foram observados níveis ideais para o conforto das aves. Em relação aos índices de desempenho produtivo, verificou-se que todos, em ambos os sistemas de acondicionamento do ambiente, na fase inicial e final, não apresentaram diferença entre si, posicionando-se dentro da faixa considerada compatível com os valores médios obtidos pela avicultura de corte do Brasil.Universidade Federal de Viçosa - UFV2010-12-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/17910.13083/reveng.v18i6.197Engineering in Agriculture; Vol. 18 No. 6 (2010); 461-471Revista Engenharia na Agricultura - REVENG; v. 18 n. 6 (2010); 461-4712175-68131414-398410.13083/reveng.v18i6reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/179/145Menegali, IreneBaêta, Fernando da CostaTinôco, Ilda de Fátima FerreiraCordeiro, Marcelo BastosGuimarães, Maria Clara de Carvalhoinfo:eu-repo/semantics/openAccess2023-01-19T12:50:12Zoai:ojs.periodicos.ufv.br:article/179Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T12:50:12Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false
