How positive reinforcement training is being applied in commercial pig settings and what welfare benefits it delivers at scale.
Positive reinforcement training in commercial pig settings represents a paradigm shift from conventional coercive handling toward a relationship-based approach with genuine welfare benefits. Pigs that have been trained to cooperate with handling respond to routine management events — weighing, health checks, moving between pens — with reduced stress and without the flight responses that cause injury to pigs and handlers. The training investment is front-loaded but the welfare dividend extends across the entire production period. Commercial adoption has been slower than the evidence warrants, partly because of unfamiliarity and partly because the benefits — reduced cortisol, fewer injuries, better meat quality — are harder to see immediately than the time cost of training sessions.
