Pigs are highly intelligent animals capable of complex problem-solving, social learning, and emotional responses, yet their cognitive welfare needs receive little attention in commercial farming systems.
Pigs are cognitively among the most sophisticated farmed animals, with capacities for learning, problem-solving, emotional reasoning, and social complexity that are regularly underestimated. In conventional farming environments that offer minimal cognitive stimulation, pigs experience boredom, frustration, and what researchers call negative cognitive bias — a pessimistic interpretation of ambiguous signals that indicates poor welfare state. Providing environments that engage pig intelligence through foraging challenges, novel objects, and varied social opportunities improves welfare in ways that behavioral and physiological indicators confirm.
