Rhinoceros in zoos face specific welfare challenges from their solitary nature, complex nutritional requirements, and sensitivity to environmental conditions, alongside their critical conservation status.
Rhinos are long-lived, intelligent animals whose welfare in captivity depends on detailed attention to diet, substrate, social management, and environmental complexity. Iron storage disease — once poorly understood — has been a significant killer of captive rhinos and requires dietary management that differs substantially from wild feeding patterns. Foot problems from hard substrates and reduced movement are a chronic welfare issue in many facilities. Modern best-practice rhino keeping uses extensive positive reinforcement training to enable voluntary participation in health management, reducing the trauma of restraint and anaesthesia. Zoos holding rhinos carry both a welfare obligation to their individual animals and a conservation responsibility for species on the edge of extinction.
