Abstract (English): Broilers during the first phase should be protected from cold stress, especially in the winter, cold nights and early mornings. To protect animals, poultry producers have used different strategies, including the use of multilayer of curtain, to increase the thermal insulation and reduce heat losses, also decreasing the permeability to the external air. In this context it is important to give special attention to the indoor air quality of poultry sheds as part of a production under animal welfare parameters. This study was conducted in the municipality of Barbacena, MG, in Brazil, and aimed to assess air quality at the level of the chickens and workers, specifically concentrations of ammonia, carbon dioxide and carbon monoxide, in a poultry house naturally ventilated during the first phase of life of broilers in the winter period, and the influence of insulation level with side curtains on concentrations of ammonia. During the first experimental week, ammonia levels exceed acceptable values, and statistical difference was found between the concentrations of ammonia for different insulation levels with side curtains.

Abstract (Spanish): Los pollos de engorde durante la primera fase deben estar protegidos del estrés por frio, especialmente en el inverno, noches y madrugadas frías. Para proteger a los animales, los avicultores han utilizado diferentes estrategias, entre ellas está el uso de varias capas de cortinas para aumentar el nivel de aislamiento térmico y disminuir las pérdidas de calor, disminuyendo también la permeabilidad con el aire externo. En este contexto, es importante dar especial atención a la calidad del aire interno de los galpones avícolas como parte de una producción bajo parámetros de bienestar animal. El presente estudio fue realizado en el municipio de Barbacena, MG, en Brasil, y tuvo como objetivo evaluar la calidad del aire al nivel de los pollos y los trabajadores, específicamente de las concentraciones de amoniaco, dióxido de carbono y monóxido de carbono, en un galpón avícola naturalmente ventilado durante la primera fase de vida de pollos de engorde en el período de inverno, y la influencia del nivel de aislamiento con cortinas laterales sobre las concentraciones de amoniaco. Durante la primera semana experimental, los niveles de amoniaco sobrepasaron los valores aceptables, y se encontró diferencia estadística entre las concentraciones de amoniaco para los diferentes niveles de aislamiento con cortinas laterales.
