YAK

(Redirected from Yaks)

The 'yak' (''Bos grunniens'') is a long-haired bovine found in Tibet and throughout the Himalayan region of south Central Asia, as well as in Mongolia. In addition to a large domestic population, there is a small, vulnerable wild yak population. In Tibetan, the word ''yak'' refers only to the male of the species; a female is a ''dri'' or ''nak''. In most languages which borrowed the word, including English, ''yak'' is usually used for both sexes.
Yaks, both domestic and wild, are herd animals. Wild yaks stand about two meters tall at the shoulder and domesticated yaks are about half that height. Both types have long shaggy hair to insulate them from the cold. Wild yaks can be either brown or black. Domesticated ones can also be white. Both males and females have horns.

Wild yaks

Wild yaks can weigh up to 1,000 kg (2,200 lb). They usually form groups of between 10 and 30 animals. Their habitat is treeless uplands like hills, mountains and plateaux between 3,200 m (10,500 ft) and roughly 5,400 m (18,000 ft). They eat grasses, lichens and other plants. They are insulated by dense, close, matted under-hair as well as their shaggy outer hair. [1] Yaks secrete a special sticky substance in their sweat which helps keep their under-hair matted and acts as extra insulation. This secretion is used in traditional Nepalese medicine. Many wild yaks are killed for food by the Tibetans; they are now a vulnerable species.[2]

Domesticated yaks

Domesticated yaks are kept primarily for their milk, fiber, meat and as beasts of burden. They transport goods across mountain passes for local farmers and traders as well as in support of climbing and trekking expeditions; their dung is even burned as fuel. Yak milk is often processed to a cheese called ''chhurpi'' in Tibetan and Nepali languages, and byaslag in Mongolia. Often the pack animals are actually crossbreeds of the yak and ''Bos taurus'' (common domestic cattle). These are known in Tibetan as ''dzo'' or ''dzopkyo''. Unlike cattle, yaks grunt rather than moo.
Yak fibers are soft and smooth, in several colors, including shades of gray, brown, black and white. The length of yak fiber is about 1.2 inches. It is combed or shed from the yak and then dehaired. The result is a splendid downy fiber that can be spun into yarn for knitting.
More recently, sports involving domesticated yaks, such as yak skiing, [Nat-han ] [ Tede-schi] or yak polo, are being marketed as tourist attractions in Central Asian countries.

In sport

In parts of Tibet Yak racing is considered a high source of entertainment at traditional Tibetan festivals.
