Moving beyond preventing suffering, positive welfare science identifies what pigs need to thrive — play, exploration, social bonding, and environmental engagement that make life worth living.
Positive welfare science has transformed how we understand pig wellbeing. It is no longer sufficient to ensure pigs are not sick, not injured, and not in pain — good welfare requires that pigs can experience pleasure, engage in species-appropriate behaviors, and have positive emotional states. In practice, this means enrichment is not optional: rooting material (straw, compost, or silage), novel objects, space for social play, and varied environments are welfare necessities. Farms achieving high positive welfare scores show lower disease incidence, reduced aggression, and better feed conversion — positive welfare and productivity are aligned. Assessment tools like the Welfare Quality protocol explicitly measure positive indicators including social behavior, play, and exploration quality, allowing farmers to track and improve welfare outcomes over time.
