Pigs are among the most cognitively sophisticated farmed animals, demonstrating self-awareness, empathy, and learning abilities that make the deprivation of intensive farming systems particularly significant welfare concerns.
The cognitive sophistication of pigs creates a welfare obligation that goes beyond providing adequate feed and space. Animals capable of self-recognition, empathy, and complex learning have rich inner lives whose deprivation in barren, confined systems constitutes genuine suffering — not just physical privation. A pig in a barren farrowing crate cannot express curiosity, build social relationships, or engage in the extended foraging behaviour central to its evolved psychology. The mismatch between pig cognitive capacity and intensive farming conditions is stark, and the welfare science supports treating pig boredom, frustration, and social deprivation as serious welfare harms alongside physical disease and injury.
