Bear bile farming in China, Vietnam, and Laos keeps thousands of bears in small cages for bile extraction used in traditional medicine. International welfare campaigns have reduced the industry, but thousands of bears continue to suffer.
Bear bile farming causes some of the most severe and prolonged welfare suffering documented in any farming system. Bears spend their entire lives in cages often too small to turn around, subjected to repeated painful extraction procedures and the chronic infection and pain associated with implanted catheter systems. The psychological deterioration of farmed bears is extensive — stereotypic behaviour, self-mutilation, and chronic fear states are universal in documented populations. The synthetic alternative UDCA is medically equivalent and widely available. Consumer campaigns in East Asian markets have successfully reduced demand, particularly among younger consumers. Sanctuaries provide rehabilitation for rescued bears, but the process of psychological recovery from bile farming conditions takes 2-5 years of patient, enrichment-based care.
