China is the world's biggest consumer of donkey meat and is looking for additional supplies. The gelatin found in the animals' skin has made them a target, leading to a growing wave of donkey slaughtering in several African countries, as gangs seek to fuel a lucrative, and in South Africa illegal, trade.
The donkey-hide gelatin has no commercial value in Africa but is highly sought after in China as an ingredient for traditional medicine to treat health problems such as anaemia and menopause-linked ailments.
Hooves also contain gelatin, while the meat, consumed in parts of China, is believed to be more nutritious than beef and is enjoyed in burgers or stewed.
