Feral horse and donkey populations worldwide face welfare challenges including overpopulation, drought, disease, and controversial management interventions.
Feral horse welfare involves difficult trade-offs. Unmanaged populations grow until resource depletion causes widespread starvation and disease, causing mass suffering. Management through roundups causes acute stress and injuries. Lethal control is politically controversial but may represent the most welfare-efficient outcome in some contexts. Fertility control vaccines offer a more humane management option where populations are accessible, though logistics limit their applicability at scale.
