Positive reinforcement training improves pig welfare by reducing fear of handlers, enabling voluntary health procedures, and enriching the cognitive environment of farmed pigs.
Positive reinforcement training transforms the human-pig relationship from one based on force and aversion to one built on trust and voluntary cooperation. Pigs trained with food rewards quickly learn to approach rather than flee from handlers, reducing the chronic fear that is prevalent in poorly managed commercial systems. Training enables veterinary procedures with minimal stress, reducing the need for physical restraint that causes distress to both pigs and handlers. Beyond practical benefits, training provides cognitive engagement that improves psychological welfare in species that are active problem-solvers in natural conditions. The stockperson-animal relationship is one of the most powerful determinants of farm animal welfare outcomes.
