Not only can yaks breathe well in the high altitudes of the Himalayas, but they can also withstand the frigid temperatures which can drop below -40° F. Yaks are protected by their thick, wooly undercoat, long fur, and outer fatty layer which insulates their body.
Milk:Yak milk is golden in color and very rich in fat at 7-8%. It has a sweetish taste.Milk production from yaks is seasonal. Hybrid yaks tend to yield more milk.Milk can be rendered into powder, butter, yogurt, cheese, and Kurut.Kurut is made from curdled milk which is churned, boiled and then drained.The cream from yak milk, called Kaimak, thick, sweet, and yellow with a flavor like almonds.Yak cheese is a hard, Swiss style cheese that fetches high prices in Kathmandu.Tea is made with yak milk and is a staple part of the diet of Tibetan yak herders. Milk is also added to mushrooms to make a milk-mushroom stew.Butter is the principal product from yak milk. It is a staple food for herdsmen and locals. Tea can be made from butter.
Wool: Yaks have a thick wooly layer under their long fur which they molt every spring. A single yak can produce 1 - 1½ lbs. of wool per year. This wool is comparable to Cashmere and is spun into yarn to make clothes, blankets, mats, and fabrics. " Wooly" yaks are a variation that have more wool and hair than other yaks.
-Tail: The tail of a yak is a luxuriant bush of long hair very much like a horse's tail, and not like the long, bony tails of ordinary cattle with only a tuft of hair at the end. Yak tails are used as religious offerings, ornaments, fly whisks, dusters, and in Hindu and Buddhist rituals.Yaks hold their tails erect when galloping.
Yaks are excellent for use on the trail. They can pack up to 150 pounds at two years of age. They are extremely sure footed and easy on the trails and surrounding countryside. They can go places that horses usually cannot.
Dung: Since trees are very scarce on the Tibetan Plateau, yak dung is the major source of fuel. Yak dung is collected and dried. It burns just like wood and is used for cooking and heat. However, it is unavoidable to breathe the smoke emitted by the burning dung which is harmful to the throat and lungs. Yak dung is used to build 'yurts' - native huts or houses.
