Scientific research has identified specific enrichment types that most effectively improve pig welfare in commercial settings.
Research on pig enrichment has moved beyond simply providing objects to understanding motivation and behaviour. Pigs are most motivated by complex, foraging-relevant materials they can root in and manipulate. The challenge is providing sufficient enrichment at commercial scale without compromising biosecurity. Effective enrichment significantly reduces aggression, tail biting, and stereotypies while improving growth rates and immune function.
