Deer farming for venison and velvet is practiced in New Zealand, UK, and elsewhere. These species retain strong wild instincts that create specific welfare challenges in farming systems.
Deer farming welfare is fundamentally challenged by the species' retained wildness. Unlike cattle and sheep domesticated over thousands of years, deer have been farmed for only a few decades and retain the acute stress responses of wild prey animals. Every handling event - vaccinations, weaning, TB testing - causes a stress response orders of magnitude greater than in cattle. Capture myopathy (muscle damage from extreme stress and exertion) causes death in deer that would be uninjured in equivalent handling of sheep or cattle. Velvet harvesting, regardless of analgesia protocol, causes pain and handling stress. Minimizing handling frequency and duration, and using appropriate low-stress facilities, are the primary welfare interventions available.
