Scientific measurement of enrichment effectiveness in farm animals ensures resources are directed toward interventions that genuinely improve welfare rather than fulfilling regulatory boxes.
The welfare science of enrichment is moving beyond simple provision requirements toward understanding what kinds of enrichment actually improve subjective states. A toy in a pig pen may satisfy a regulatory checkbox while having no measurable impact on cortisol, behavioral diversity, or cognitive bias testing outcomes. Rigorous measurement of enrichment effectiveness guides both farm management and policy design. The goal is not enrichment as a formality but enrichment that genuinely gives animals better lives.
