Bison farming has grown substantially across North America, with welfare challenges arising from the species wild ecology, limited domestication, and handling requirements.
Bison welfare reflects their status as the least domesticated major farmed ungulate in North America. Their retained flight responses, herd cohesion instincts, and unpredictability in handling situations create welfare challenges in both directions — handling stress for animals, and safety risks for handlers using inappropriate equipment. Low-stress handling facilities designed for bison, using their natural flight zone and point of balance, dramatically reduce handling welfare costs. The relatively natural production systems used in most bison farming — grass-based grazing with minimal confinement — align more closely with species-appropriate behavior than intensive cattle systems. However, branding, castration, vaccination, and processing all cause welfare harms requiring appropriate management. Bison farming represents an intermediate welfare position — better than most intensive livestock in basic life conditions, but still requiring active management of handling stress.
