Foraging-based enrichment design for pigs provides the most effective approach to meeting rooting and exploratory motivations that are severely frustrated in barren indoor systems.
Foraging-based enrichment design addresses the most fundamental and pervasive welfare deficit in commercial pig production — the frustration of rooting motivation in animals evolved to spend most of their active time engaging with complex substrates. The science shows that rooting motivation is hardwired and independent of hunger, meaning that providing adequate food does not satisfy the behavioral need. Effective foraging enrichment design incorporates substrate complexity that enables rooting and exploration, novelty rotation to prevent habituation, and integration into the feeding system to extend foraging time. The difference in behavioral welfare between pigs with access to complex foraging environments and those in barren conditions is profound and measurable.
