Modern pig welfare science is moving beyond simply preventing suffering to actively measuring and promoting positive welfare states — pleasure, play, curiosity, and social bonding. This shift has significant implications for farm design and management.
The positive welfare paradigm challenges the assumption that absence of obvious suffering equals good welfare. A pig living a genuinely good life shows active engagement with its environment, forms social bonds, plays, explores, and shows positive anticipatory responses to feeding and keeper interaction. These states can be measured using validated behavioural and cognitive methods that provide farms with actionable welfare improvement targets beyond simple compliance with minimum standards. The implications for farm design are significant: enrichment provision, stable social groups, positive human-animal relationships, and freedom of movement are not luxuries but prerequisites for positive welfare. Consumer certification schemes that include positive welfare indicators (beyond the Five Freedoms) are an emerging market category aligned with this science.
