Yellow-backed duiker
These forest dwelling antelope feed selectively on plants or plant parts such as shoots, roots, leaves, and buds, but their diet is mainly made up of fruits. The yellow-backed duiker is more efficient at digesting poor quality food than most other duiker species. This allows them to eat large, low quality fruits. Their diet makes them very hard to keep in captivity as most domesticated fruits are not well suited to their low fiber requirements. They are considered concentrate selectors, meaning they eat "diets relatively low in fiber, have a well developed ability to forage selectively, a rumen bypass, a rapid passage and high fermentation rate for starch, and they frequently encounter toxins."
Tibetan antelope
The Tibetan antelope or chiru ("Pantholops hodgsonii") (, pronounced ; ) is a medium-sized bovid native to the Tibetan plateau. Fewer than 150,000 mature individuals are left in the wild, but the population is currently thought to be increasing. In 1980s and 1990s, they had become endangered due to massive illegal poaching. They are hunted for their extremely soft, light and warm underfur which is usually obtained after death. This underfur, known as "shahtoosh" (a Persian word meaning "king of fine wools") , is used to weave luxury shawls in Jammu and Kashmir, northern India. Shahtoosh shawls were traditionally given as wedding gifts in India and it takes the underfur of 3-5 adult antelopes to make one shawl. Despite strict controls on trade of shahtoosh products and CITES listing, there is still demand for these luxury items. Within India, shawls are worth $1,000-$5,000, internationally the price can reach as high as $20,000.
