In study, infrared thermography (IRT) was assessed as a means of detecting the changes in body temperature in poultry coccidiosis, as well as determining IRT used in imaging and measuring the regional changes in skin temperature that occur in the poultry during this infection. Broilers were inoculated with 5×10 2 or 1×10 3 oocysts of Eimeria tennella.The group of control animals remained non-inoculated throughout the study. The study showed that coccidiosis affected temperature homeostasis in animals significantly. Body surface temperature decreases significantly (p < 0.05). IRT is a promising tool that may provide a more objective an quantitative information about thermal status of animals.
