A bear in a crusher cage on a bile farm, Sichuan Province, China. Bile bears, sometimes called battery bears, are bears kept in captivity to harvest their bile, a digestive fluid produced by the liver and stored in the gallbladder, which is used by some traditional Chinese medicine practitioners. It is estimated that 12,000 bears are farmed for bile in China, South Korea, Laos, Vietnam, and Myanmar.

The bear species most commonly farmed for bile is the Asiatic black bear (Ursus thibetanus), although the sun bear (Helarctos malayanus), brown bear (Ursus arctos) and every other species are also used (the only exception being the Giant Panda which does not produce UDCA). Both the Asiatic black bear and the sun bear are listed as Vulnerable on the Red List of Threatened Animals published by the International Union for Conservation of Nature. They were previously hunted for bile but factory farming has become common since hunting was banned in the 1980s.
The bile can be harvested using several techniques, all of which require some degree of surgery, and may leave a permanent fistula or inserted catheter. A significant proportion of the bears die because of the stress of unskilled surgery or the infections which may occur.

Farmed bile bears are housed continuously in small cages which often prevent them from standing or sitting upright, or from turning around. These highly restrictive cage systems and the low level of skilled husbandry can lead to a wide range of welfare concerns including physical injuries, pain, severe mental stress and muscle atrophy. Some bears are caught as cubs and may be kept in these conditions for up to 30 years.
