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.
