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."

The Tibetan antelope or "Chiru" lives in one of the harshest environments on earth, at an altitude of over 5,000 metres. Their special type of down fur, which is both very light and warm, allows them to survive in the freezing conditions of the plateau where they gather at one point of the year. They are migratory animals, moving down from Mongolia to Tibet, and traditionally followed closely by the nomads who also make that journey every year. The nomads would hunt the antelope for hide, meat, bones, horns and fur pelts.
