Pigs' remarkable cognitive abilities create welfare needs beyond physical enrichment. Meeting cognitive needs through varied, challenging enrichment dramatically improves pig welfare.
Pig cognitive enrichment addresses a welfare need that goes beyond physical stimulation to genuine mental engagement. Pigs that can investigate, manipulate, solve, and discover are occupying their considerable cognitive capacity in ways that prevent the boredom and frustration driving welfare problems like tail biting and aggression. The welfare opportunity is that cognitive enrichment is achievable at commercial scale through attention to novelty rotation and variety rather than expensive permanent installations. A pig discovering a new object in its environment, manipulating a puzzle feeder, or exploring a new substrate is expressing cognitive capacity in a welfare-positive way that simple chains and plastic objects cannot provide.
