Abstract: The aim of the present study was to evaluate the thermal environment and noise levels in swine farrowing cells built with masonry or slate. Thermometers and sound level meter equipment were used to measure the thermal comfort variables. Inside the cells and for the statistical analysis, twelve sows and one hundred thirty-nine piglets were used, distributed in a randomized blocks design in a split-plot arrangement. The results showed that in the morning, in both treatments, the thermal comfort conditions were more suitable for sows, while in the afternoon it was more suitable for piglets. The noise was lower in the masonry cells. Overall, the environment inside in the cells built with slate presented lower relative humidity and, higher BGHI and temperature than those built with masonry. The noise level remained within the thresholds considered as ideal for swine in both treatments.
