Comprehensive research on enriched pig housing demonstrates clear welfare benefits — and reveals that production performance is maintained or improved when enrichment addresses behavioral needs.
The evidence for enriched pig housing is among the strongest in farm animal welfare science. Pigs given manipulable materials that allow rooting, chewing, and exploration show measurably better welfare across behavioral, physiological, and health indicators. The welfare improvement is not modest — the difference between barren concrete and well-enriched housing represents a fundamental quality-of-life shift for intelligent, curious animals. The production evidence showing no performance penalty removes the primary industry objection. What remains is inertia and the capital cost of system change.
