What member of the cow family lives in Himalayas?

The answer is yak.

Yaks are large, shaggy-haired bovines that are native to the Himalayan mountains of Central Asia. They are well-adapted to the cold, harsh climate of the Himalayas, and are often used as pack animals by people who live in the region. Yaks are also a source of food, milk, and fur for the people of the Himalayas.
