Enrichment for pigs is a legal requirement in many countries, but the quality and type of enrichment matters enormously - understanding the science helps ensure it genuinely improves welfare.
Enrichment science for pigs has moved beyond the question of whether enrichment matters (it does) to what types of enrichment actually meet behavioural needs. The evidence is clear: substrate-based enrichment that allows rooting is far superior to object-based enrichment like chains or rubber toys. Yet many farms provide chains or suspended ropes in technical compliance with minimum welfare legislation while failing to meet the spirit of the requirement. Consumers and advocates who understand enrichment science can distinguish meaningful welfare claims from token compliance.
