Abstract
Infrared thermography technology is a noninvasive method that has been used to indicate thermal biometric changes in animal metabolism resulting from increased body temperature and changes in blood flow in response to environmental or physiological conditions. Thus, this technology can be a useful tool and general stress indicator as well as indicate inflammatory processes, pain and disease. Therefore, this manuscript aims to review the use of this technology in animal production, addressing aspects of heat and physiological stress, metabolism, nutrition, inflammatory processes, diseases, ectoparasite detection and reproduction.
