Emotions in pigs manifest both in their own experiences and in their sensitivity to the emotional states of other group members, which includes the formation of social bonds. Personality traits, such as aggressiveness, influence behaviour during conflicts, while physiological reactions can indicate positive or negative emotional states. A modern approach to livestock farming utilizes data from traditional methods as well as new technologies, including sensors, automated systems, and artificial intelligence, opening the way to a deeper understanding of pig emotions and ensuring their welfare.
