|Abstract:||The objective of this study was to model and evaluate, through fuzzy logic, the level of thermal comfort experienced by housed animals as a function of their physiologic variables of rectal temperature (RT) and breath rate (BR), and setting their critical thresholds. The database was setup using two distinct environments: Subtropical climate (São Pedro area, Brazil) and mediterranean climate (Évora area, Portugal). Holstein cows temperature and breath rates were obtained in order to build a physiologic parameters database. meteorological data of environment temperature and air relative humidity were obtained for physical analysis during a 24 hours interval every 30 minutes. Data minning techniques were used for the initial data analysis aiming to build a decision making three and the further construction of rule database. For that, the computational program WEKA® was used. The results obtained were applied for the fuzzy logic application, using the Fuzzy Logic Toolbox do MATLAB® 6.1 software, according to AMENDOLA et al. (2005b). The use of this tool allowed the establishment of thermal comfort parameters for total confined Holsteins cows.|
