Research into pig cognition — including emotional contagion, self-recognition, and complex learning — has profound implications for how we approach pig welfare.
The emerging science of pig cognition makes a compelling moral case for substantially higher welfare standards. Pigs are not merely productive units — they are cognitively complex beings capable of learning, emotional experience, and social relationships. Their confinement in barren crates and pens without enrichment or meaningful social interaction represents a profound mismatch between their cognitive needs and their physical environment. The scientific evidence for pig intelligence strengthens existing welfare arguments and demands a commensurate ethical response in farming practices and legislation.
