Abstract
Este estudo teve o objetivo de avaliar distintos programas de acionamento dos sistemas de climatização (ventiladores e nebulizadores), visando a aprimorar o ambiente interno e o bemestar das aves, evitando possíveis perdas produtivas e gastos excessivos em energia elétrica. O estudo foi conduzido em dois aviários localizados no município de Uberlândia - MG, durante a época de baixa umidade relativa do ar (junho a dezembro). Os aviários foram comparados sob os parâmetros de concentrações de CO2, temperatura e umidade relativa do ar, temperatura superficial da cama e índices produtivos. Os dados climáticos foram submetidos à análise de variância, e os dados produtivos submetidos ao teste de Qui-quadrado, utilizando-se do software MINITAB V.14. Os resultados apontados pelos tratamentos 1 e 2 mostraram que as concentrações de CO2 no ar (372,70 e 379,46 ppm, respectivamente) estiveram abaixo dos limites máximos recomendados internacionalmente para ambos os sistemas. As temperaturas internas (26,23 e 26,56 ºC, respectivamente) estiveram sempre acima do recomendado para as aves, e os níveis de umidade relativa do ar (69,73 e 70,42, respectivamente) estiveram, em média, na faixa recomendada, para ambos os sistemas. Conclui-se que o aviário programado para acionar o sistema de climatização mais tardiamente consumiu menos energia elétrica, apresentou melhor conversão alimentar, menor incidência de artrite, porém maior percentual de mortalidade.
This study aimed to evaluate different turn on systems of climatization (fans and fogging sprinklers) to improve the internal environment and the birds' welfare, avoiding productive losses and expensive wastes in electrical energy. The study was conducted in a commercial property with two poultry houses, located in Uberlândia, MG, Brazil, during the phase of low relative humidity of the air (June to December). The poultry houses were compared under the parameters of concentration of CO2, temperature and relative humidity, surface temperature of the litter and production indexes. The climatic data were subjected to analysis of variance and productive data submitted to chi-square, using the software Minitab, V.14. The results showed in treatments one and two that concentrations of CO2 in the air (372,70 and 379,46 ppm, respectively) were below the internationally recommended limits for both systems. The internal temperatures (26,23 e 26,56 ºC, respectively) were always above the recommended for birds, and the levels of relative humidity (69,73 e 70,42, respectively) were on average in the recommended range for both systems. The conclusion is that the poultry house programmed to trigger the air-conditioning later, consumed less electricity, had better feed conversion, lower incidence of arthritis, but a higher percentage of mortality.
