Research demonstrates that pigs trained with positive reinforcement show reduced fear of humans, better welfare indicators, and calmer handling - benefiting animals and stockpersons alike.
The relationship between pigs and the people who care for them is a significant determinant of pig welfare. Stockpersons who interact positively with pigs - rather than using aversive handling - produce calmer animals with lower stress hormones. Training farm staff in positive pig interaction is a high-leverage welfare intervention that costs little but improves welfare measurably. Welfare is not just about housing - it is about relationships.
