A hybrid of a cow and a yak. A dzo, zo, zho, dzho is a hybrid between the yak and domestic cattle. The word dzo technically refers to a male hybrid, while a female is known as a dzomo or zhom. There is also the English language portmanteau term of yattle, a combination of the words yak and cattle, as well as yakow, a combination of the words yak and cow. The domestic yak (Bos grunniens) is a long-haired domesticated bovid found throughout the Himalayan region of the Indian subcontinent, the Tibetan Plateau and as far north as Mongolia and Siberia. It is descended from the wild yak (Bos mutus bovid). In Nepal, Tibet and Mongolia, domestic cattle are crossbred with yaks. This gives rise to the infertile male dzo as well as fertile females known as dzomo or zhom, which may be crossed again with cattle. Animal. 4K 3840×2160.
