Research demonstrates that pigs experience positive emotional states. Farming practices that foster positive emotions are an emerging welfare frontier beyond harm reduction.
Positive emotions in pigs represent the frontier of farm animal welfare science. Traditional welfare focused on preventing suffering; the emerging paradigm asks what a good life for a pig actually looks like. Evidence shows that enriched, socially stable pigs with positive human relationships experience measurable positive emotional states — they are curious, playful, and optimistic about their environment. Farming practices designed to foster these states represent a meaningful welfare advance beyond simply reducing harm.
