Understanding wild boar natural foraging behavior informs welfare standards for captive and farmed wild boar populations.
Wild boar in captive settings — game farms, wildlife parks, or rescue facilities — face significant welfare challenges rooted in the mismatch between their intensive foraging motivation and constrained environments. Rooting is not a behavior that enrichment items can fully replace — the sensory feedback of moist soil, the olfactory search, and the physical effort of excavation are all components of an intrinsically motivated behavioral sequence. Providing deep substrate, scatter feeding that requires foraging work, and adequate social groupings are the minimum welfare requirements for captive wild boar. Bare concrete or hard ground housing without foraging substrate should be considered inadequate by any welfare standard.
