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."
Hoh Xil
Despite the harsh climate, Hoh Xil is home to more than 230 species of wild animals, 20 of which are under Chinese state protection, including the wild yak, wild donkey, white-lip deer, brown bear and the endangered Tibetan antelope or "chiru". The abundant plateau pika, a small burrowing rodent, is the main food of the region's brown bears; the bears also feed on the yak and antelope. The hitherto little-known region, as well the struggling Tibetan antelope, or chiru, became household names in China upon the release of the film "" in 2004. Zhuonai Lake (卓乃湖) in Hoh Xil is known as a gathering place for the Tibetan antelope.
