Play in pigs is a positive welfare indicator. Understanding what play looks like in pigs and what conditions enable it helps farmers and auditors identify genuinely good welfare environments.
Pig play is one of the clearest behavioral signals of good welfare. When pigs play — running, chasing, mock-fighting, jumping — they are demonstrating not just the absence of suffering but the active presence of positive emotional states. This is why play is used as a validated welfare indicator: its presence is meaningful evidence of genuinely good welfare, not just acceptable welfare. The conditions that enable play — adequate space, enrichment, stable social groups, and physical health — are the same conditions that produce good welfare across all dimensions. A farm where pigs play regularly is doing something right; a farm where play is never observed is failing its animals, regardless of what other metrics show.
