Rooting and foraging are the most strongly motivated natural behaviors in pigs, yet most farmed pigs are housed on concrete or slatted floors with no opportunity to express them. Addressing this fundamental need transforms welfare outcomes.
Denying pigs the opportunity to root and forage represents one of the most significant unresolved welfare issues in intensive pig production. The motivation to root is not a preference that diminishes without expression — it remains strong and is redirected toward available targets, primarily pen mates. Tail biting, which begins as redirected rooting, can escalate to severe tissue damage, infection, and death if not managed. The widespread practice of routine tail docking treats the symptom rather than the cause, and is prohibited in many jurisdictions. Genuine solutions require providing substrate — straw, soil, or compost — that satisfies the foraging drive. The economic and logistical barriers to substrate provision in fully slatted systems are real but surmountable with system redesign.
