Pigs are highly intelligent and curious animals whose behavioral needs for rooting, foraging, and social interaction are severely restricted in conventional confinement housing systems.
Pigs in barren confinement environments suffer from chronic behavioral frustration. Without rooting substrate, they redirect foraging behavior onto penmates, causing injuries that require management through painful tail-docking. Enrichment provision addresses the root cause rather than the symptom. Research consistently shows that pigs with access to manipulable materials show lower stress hormones, fewer injuries, and higher welfare indicator scores. Transitioning to enriched systems is achievable within existing farm infrastructure and represents one of the highest-impact welfare improvements per animal in the industry.
