Evaluation of Body Surface Temperature in Pigs Using Geostatistics

This paper explores the potential of infrared thermography and geostatistics in animal production presents results application combination these techniques, contributing significantly to efforts obtain animals’ responses environments which they are located thereby ensuring improvements productivity welfare. The objective was verify variability surface temperature pigs submitted different climate control systems using geostatistics. Three growing animals per stall were selected. Dry bulb (Tbd, °C), relative humidity (RH, %) thermal images recorded at 08:00 12:00 h. To analyze data, semivariograms made, theoretical model validated kriging maps constructed. mean pen with adiabatic evaporative cooling (AEC) ranged from 32.40 36.25 °C; for forced ventilation (FV) pen, range variation 32.51 36.81 °C. In group (Con), natural ventilation, average 37.51 38.45 geostatistical analysis provided a mathematical capable illustrating caudal–dorsal regions according subjected.
