Zoo rhinoceroses present unique welfare challenges including horn management, territorial needs, and the psychological impacts of captivity on these large, complex animals.
Zoo rhinoceroses face welfare challenges distinct from other large mammals. Their space requirements are substantial - rhinos patrol large territories in the wild. Horn trimming, while sometimes necessary for safety, raises welfare questions about altering a key sensory and social tool. The procedure itself is not painful when done correctly under anesthesia or with proper technique on the dead keratin, but frequent repetition has unknown cumulative effects. Social housing presents challenges: white rhinos benefit from companions while black rhinos may stress in close proximity. Best-practice zoos invest heavily in substrate variety, mud wallows, browse feeding, and sensory enrichment to improve rhino welfare.
