Modern pig welfare science has developed validated indicators of positive welfare states, moving beyond the Five Freedoms to measure whether pigs are experiencing good lives, not just avoiding bad ones.
Positive welfare assessment transforms the frame from preventing suffering to actively providing good lives. A pig farm can comply with minimum welfare standards and still house animals that are chronically bored, frustrated, and experiencing predominantly negative states. Positive welfare indicators — play, exploration, relaxed posture, social grooming — reveal whether animals are thriving. Research shows that simple management changes including straw provision, social stability, and positive human-animal interaction reliably increase positive welfare indicators. Training farm staff to recognize and promote positive welfare indicators shifts the culture from compliance toward genuine concern for animal experience.
