Positive welfare for pigs goes beyond preventing negative experiences to actively promoting pleasurable states, play behavior, and affective wellbeing, representing a significant advance in welfare science and practice.
The shift toward positive welfare assessment in pigs represents a conceptual advance from suffering reduction to promoting flourishing. Pigs in enriched environments with appropriate social structures and positive social interactions demonstrate behavioral indicators of positive affect - they engage in play, show approach behaviors toward enrichment, and demonstrate anticipatory responses to positive stimuli. Positive welfare provision and negative welfare reduction are complementary: removing pain and fear creates space for positive states, while positive welfare investment reduces the stress that drives aggression and other negative welfare indicators.
