The Brazilian poultry industry is the activity that has the largest and most advanced technological collection from the agricultural sector in the country, which does not imply that productive problems still do not persist, specifically related to the ambience. In order to optimize the production performance in poultry sector, it is necessary to adequate the aviaries, with techniques that address the thermal and hygienic issues of the internal environment of the grow out houses and a more efficient use of energy. This study assessed the thermal and air internal environments in three grow out houses of different types, representative of poultry production in South America: the first one set with a positive pressure ventilation system in tunnel mode, the second one set with lateral positive pressure ventilation system and the third with negative pressure ventilation system in tunnel mode. Data have been collected during the first phase of growth, in the winter and spring of 2011. Air quality analyzes have been conducted verifying environment s concentrations of CO, CO2 and NH3 and thermal comfort was assessed, through maps of temperature, relative humidity and ITU, in addition to modeling of the internal thermal behavior in CFD for the grow out house with negative pressure ventilation system in tunnel mode. In each chapter, statistical analyzes have been conducted specific to the thermal environment, air quality, and finally to validate the computational model.
