Pig pen design profoundly affects welfare outcomes, with innovative designs providing opportunities for positive welfare expression rather than merely preventing the worst suffering.
Positive welfare in pig production goes beyond preventing suffering to enabling pleasure, play, and the expression of species-specific behaviours that characterise a good life for a pig. Well-designed pen environments where pigs can root through manipulable substrate, explore complex structures, and engage in social play create genuinely positive experiences. The difference between a pig in an enriched outdoor run and one in a bare concrete pen with a hanging chain is not merely quantitative - it represents qualitatively different welfare states. Progressive producers and researchers are demonstrating that positive welfare environments are economically viable alongside welfare-ethical.
