Positive welfare goes beyond preventing suffering — it means enabling pigs to experience genuinely good lives. Understanding what positive pig welfare looks like helps raise the bar above mere harm reduction.
Positive welfare science has transformed understanding of what good pig husbandry means. Rather than simply measuring harm — injuries, disease, stereotypies — positive welfare frameworks ask what good experiences pigs are having and how frequently. Pigs in high-welfare systems show behavioral indicators of positive states: locomotor play including running and jumping, sustained curiosity about novel enrichment objects, comfortable social interactions including nose contact and lying together. Cognitive bias testing — presenting pigs with ambiguous signals and measuring whether they interpret them optimistically or pessimistically — has emerged as a powerful proxy for overall affective state. Pigs in enriched, lower-density environments consistently show more optimistic cognitive biases. The welfare science finding that positive welfare and production efficiency are not fundamentally opposed — that healthier, less-stressed pigs grow better and use antibiotics less — provides a business case that complements the ethical argument. Positive welfare represents the goal beyond compliance: not just meeting minimum standards, but enabling genuinely good pig lives.
