Pigs demonstrate cognitive abilities comparable to dogs and young children, including tool use, emotional contagion, and self-recognition, with profound implications for farm system welfare standards.
The gap between pig cognitive capacity and the environments most commercially farmed pigs inhabit is one of the most significant ethical problems in contemporary animal agriculture. Animals capable of complex social reasoning, emotional experiences, and environmental problem-solving are housed in barren environments with restricted movement, no opportunities for rooting or exploration, and constant social instability from regrouping. Behavioral indicators of poor welfare - stereotypies, aggression, tail biting - are prevalent in intensive systems. Welfare improvement requires both environmental enrichment (rooting materials, space for play) and social stability (stable group composition).
