Yak (Bos grunniens)


The yak, also called the Tibetan yak, is a large mammal of the cloven-footed order with long, thick brown fur. It should be noted that in Tibet only male animals are called "yak" and females are called “dri”.

Since the end of the 20th century, attempts have been made to artificially settle yaks in Bulgaria, and in 2005 there were about 17 animals in the country, which increased to 18 animals in 2011 and 2012 (all in Vitinya State Hunting Farm)


Physical features

The male yaks reach weight of about 1,200 kg to 1,500 kg and height of up to 2 meters. The females are smaller in general.

The domestic yak is significantly smaller, about half the size of the wild yak. Its fur is long and thick, brown in color.

The animals live in small herds.



The wild yak is found in the Himalayas. In a number of countries (including Bulgaria) it has been successfully acclimatized or is in a process of acclimatization.

The yak is a herbivorous mammal. Its pregnancy lasts 258 days and it gives birth to one cub, which stays with the mother for a year.

The yak is kept as a domestic animal for its milk. It is also used as a working animal for plowing, transport, etc.

In the past, the yak was domesticated in Tibet, China, Central Asia, Mongolia and Nepal.

The wild yaks migrate seasonally to the lower plains to eat grass and herbs. When the weather gets too warm, they move to higher plateaus, in order to eat moss and lichen. Their thick fur and few sweat glands make life below 3,000 meters difficult even in winter.
