Pigs are highly intelligent and curious animals that require mental stimulation to maintain good welfare. Novel enrichment approaches go beyond simple toys to meet pigs' complex behavioral needs.
Enrichment deprivation in pigs causes boredom and frustration that expresses as tail-biting, aggression, and stereotypic behaviors. Research consistently shows that organic, destructible materials like straw provide far superior welfare benefit compared to plastic toys or metal chains. However, even high-quality enrichment must be genuinely accessible to all pigs in a group. Enrichment strategies should be part of a broader welfare management approach that also addresses stocking density, group stability, and disease prevention. Novel foraging challenges — hiding food in substrate — activate natural rooting behavior with significant welfare benefits.
