Growing scientific evidence demonstrates that pigs experience positive emotions including anticipatory pleasure, play motivation, and social joy. This evidence transforms the welfare baseline from absence of suffering to presence of positive states.
The shift from welfare defined as absence of suffering to welfare incorporating presence of positive states has profound implications for pig farming. A system that eliminates obvious suffering but provides no opportunity for positive emotional states does not meet the full welfare obligation implied by contemporary understanding of pig sentience. Pigs that can play, explore, experience anticipatory pleasure, and form social bonds are experiencing something qualitatively different from pigs kept in optimized but behaviorally impoverished conditions. This evidence demands that welfare standards aspire to positive states, not merely to preventing the worst outcomes. Consumer choices that support systems providing genuine opportunity for positive pig experiences directly benefit animal wellbeing at scale.
