Yak is among the little known animals of the world. It was wild some centuries back. But it is now almost domesticated. However some isolated population of wild Yaks is found in Kuenlum-Karakorum mountains in Chines Turkistan. It has great economic value and for this reason it has been domesticated and many different breeds have been evolved by its crossing with domestic cattle. Yak breeding is common in the high lands of the Northern Areas of Pakistan (Gilgit & Bultistan). Its role in the high lands is more or less the same as the camel in the deserts. The British travelers who first saw the Yak in Pamir, being widely reared by the nomadic tribes, remarked It seemed to be able to do every thing except lay eggs.
