The environment of the intensive farming of pigs directly influences their comfort and welfare; a stressful environment leads to various responses, depending on the adaptability of the animal. The facility aims to minimize these problems.The objective of this study was to evaluate the physiological and production indices of lactating mothers and piglets with the use of cooling systems and floor heating, respectively. The experimental design was completely randomized in a split plot with five replicates for the following treatments: heated floor for piglets and cooled to the parent (HPiCPa), no floor heating for piglets and cooled for the parent (CPa ) and floor without modification (FWM). We evaluated the thermal and physiological parameters of the arrays of treatments CPa and HPiCPa. In the room designated S2 without modification, we evaluated the parameters of the matrices FWM treatment. Treatment CPa showed the best result, providing greater thermal comfort for the animals, which reached an average gain 233grams per day.
