Pigs are highly intelligent, curious animals whose welfare in commercial systems is significantly compromised by barren environments. Scientific research on enrichment has produced actionable evidence for improving pig welfare at scale.
Barren pig environments cause chronic frustration, boredom, and aggression - all clear welfare harms. Enrichment is not a luxury; it addresses fundamental behavioral needs. Research shows that even simple substrate enrichment reduces tail biting incidence by 50-80%. High-welfare pig systems that provide rooting substrate, social stability, and space represent a dramatically better welfare outcome than conventional confinement. The evidence base for enrichment is robust - the barrier to implementation is economic, not scientific.
