Pigs are among the most cognitively complex farm animals, with intelligence comparable to dogs and three-year-old children. Their cognitive needs have welfare implications that extend beyond physical health.
Pig intelligence creates a welfare obligation that extends beyond physical needs. A pig confined in a barren environment is not just physically restricted - it is cognitively and experientially deprived. The same intelligence that makes pigs learnable and trainable means that pigs in unstimulating environments experience a form of chronic frustration that simpler animals might not. Environmental enrichment that provides novel objects, foraging challenges, and problem-solving opportunities addresses cognitive needs. Farms that invest in cognitive enrichment for their pigs achieve better behavioral outcomes - less aggression, less redirected behavior, more play - reflecting genuinely improved welfare.
