Scientific evidence demonstrates that environmental enrichment profoundly improves pig welfare by reducing aggression, stereotypies, and stress-related behaviors.
The science of pig enrichment has moved well beyond simply providing objects to chew on. Research shows that enrichment quality, complexity, and novelty are critical: pigs quickly habituate to static objects. Rotating enrichment items, providing rooting materials, and offering problem-solving challenges maintain engagement and produce measurable positive welfare states. Farms that implement high-quality enrichment programs report reduced tail biting, lower mortality, improved growth rates, and reduced antibiotic use, making enrichment both a welfare and economic imperative.
