In recent years, there has been a growing interest in animal welfare. Consumers of animal products are paying more attention to maintaining good husbandry conditions on the farms, but also to some of the procedures entailing pain and suffering. The most invasive procedures are castration and dehorning (disbudding), which are often performed without anaesthesia. Pain associated with tissue damage causes behavioural and physiological changes. Observation of behaviour combined with measurements of autonomic nervous system activation, and hormones of the hypothalamic- pituitary-adrenal axis, is the main method for assessing the emotional state of an animal. Immobilization and blood collection may themselves be a source of stress for these animals. There is a strong prerequisite for the development of non-invasive methods of assessing the level of animal welfare. One of them is infrared thermography. The study of eye temperature changes in cattle, measured with an infrared thermography camera, confirmed the activation of the autonomic nervous system in response to pain.
