This review presents the application and use of infrared thermography (IRT) in production animals. IRT is a non-invasive and non-contact heat detecting technology. An infrared camera measures the emitted infrared radiation from an object and then uses this information to create images (thernograms). These thermograms are evaluated by a specially analyzing software program. In live organisms, changes in vascular circulation result in an increase or decrease in tissue temperature, which is then used to evaluate the situation in that area. But there are some limitations and factors that must be considered when using IRT (sunlight, moisture, dirt, weather conditions etc). IRT has been mainly used in veterinary medicine, primarily for diagnostic purposes, especially in the diagnosis of orthopaedic diseases in horses. But IRT can be very successfully used as tool for research on livestock, pig, cattle, sheep and poultry breeding,. Areas of research include reproduction, thermoregulation, animal welfare or milking process. All of the authors using IRT recommended this method which can produce important information where conventional diagnostic techniques have exhausted their possibilities.
