Scientific evidence on pig enrichment is clear and actionable. Understanding what works and why helps translate evidence into meaningful welfare improvements at farm level.
The science of pig enrichment has reached sufficient maturity to provide clear, actionable guidance — yet implementation in the industry remains highly variable. The mismatch between what science recommends (organic, manipulable, rooting substrates) and what most commercial systems provide (indestructible rubber or hanging chains) reflects economic and infrastructure constraints as much as ignorance. Straw-based enrichment, the gold standard according to research, requires different housing infrastructure and management systems than barren slatted floors. The welfare benefit of transitioning to straw-based systems is substantial and measurable, but requires investment that industry resists without regulatory or market pressure. Consumers who support pork from welfare-certified systems create the commercial signal needed to justify this investment.
