Training pigs using positive reinforcement gives them agency and cognitive stimulation. Research shows this improves welfare indicators beyond the training sessions themselves.
Positive reinforcement training for pigs provides welfare benefits beyond the trained behaviors. The process of learning that certain behaviors produce reliable positive outcomes — agency — is intrinsically welfare-positive for intelligent animals. Pigs engaged in training sessions show reduced stress indicators and approach rather than avoid trainers, indicating improved human-animal relationships. The cognitive engagement of learning novel tasks provides stimulation that enriched environments alone may not fully provide. Even brief daily training interactions improve welfare indicators in commercial pig populations. Training also facilitates veterinary and management procedures, reducing handling stress throughout the animals' lives.
