Pigs possess cognitive abilities comparable to dogs and three-year-old children — providing cognitive enrichment meets intrinsic motivational needs and improves measurable welfare outcomes.
Pig cognitive welfare is an emerging frontier — the evidence base now firmly establishes that pigs have the cognitive complexity to experience boredom, frustration, and positive engagement with their environment. This means cognitive enrichment is not a luxury but a welfare necessity. Puzzle feeders, novel object rotation, problem-solving challenges, and social learning opportunities all meet cognitive needs that barren commercial environments entirely fail to provide. Welfare-positive pig production must address cognitive as well as physical and social needs.
