Zoo Warthog and Peccary Welfare | Animal Welfare Hub

Warthogs and peccaries are social, intelligent ungulates whose welfare in zoo settings depends on appropriate social groupings, rooting substrate, and wallowing opportunities.

Key Facts

Warthogs are native to sub-Saharan Africa and live in family groups centered on females and young
They are characterized by distinctive facial warts used in combat and rooting behavior
Peccaries are New World pigs found across the Americas in collared, white-lipped, and Chacoan species
Both species use rooting to forage and require substrate that allows this natural behavior
Wallowing in mud is important for thermoregulation and parasite control in both species
Peccaries live in large social groups and suffer welfare impacts from inadequate group size

Welfare Considerations

Warthog and peccary welfare in captivity requires providing appropriate rooting substrate, mud wallowing opportunities, and social groupings that reflect natural social structure. Rooting is a highly motivated foraging behavior that cannot be expressed on hard surfaces, causing frustration. Mud wallowing serves thermoregulatory and ectoparasite control functions that cannot be replaced by other interventions. Social needs vary by species but both benefit from appropriate group housing. Naturalistic enclosures with varied substrates, root-able areas, and wallowing pools provide the core welfare requirements for these animals.

What You Can Do

Visit zoos with naturalistic enclosures providing rooting substrate and mud wallows for suids
