Resumo: AbstractThe objective was to verify the influence of roof pitch, exposure and roofing material on the internal temperature of reduced models of animal production facilities. For the development of the research, 48 reduced models with dimensions 1.00 × 1.00 × 0.50m were used. The roof was shed-type, and models faced the North or South directions, with 24 models for each side of exposure. Ceramic, galvanized-steel and fibro tiles were used to build the roofs. Pitches varied between 20; 30; 40 and 50% for the ceramic tile and 10; 30; 40 and 50% for the other two. Inside the model, temperature readings were performed at every hour, for 12 months. The results were evaluated in a general linear model in a nested 3 × 4 × 2 factorial arrangement. As the roof pitch increased, the internal temperature within the model dropped, so utilizing sharper pitches (50%) for ceramic and fibro roofs with a larger area facing the South can provide lower temperatures within the animal production facilities. In regions where the cold is more stressful than the heat, having animal production facilities with larger roof exposure to the North may minimize the losses caused by cold stress.
