Research reveals pigs have sophisticated cognitive abilities that create welfare needs far beyond what conventional farming provides. Understanding pig cognition strengthens the case for enriched housing.
The growing body of evidence on pig cognition has profound welfare implications. These animals are not simple stimulus-response machines but engage in complex problem-solving, form individual relationships, experience boredom, and have emotional responses to their circumstances. Housing pigs in barren, monotonous environments denies them the cognitive engagement their intelligence requires, causing chronic frustration and boredom that manifests as aggression and abnormal behavior. Enriched environments with problems to solve, materials to manipulate, and social complexity better match their cognitive needs. This evidence strengthens the ethical case for substantial reform of commercial pig farming.
