They also burn the dung for fuel. They are still used for beasts of burden in areas where trucks aren't practical. Consequently, most yaks are docile animals, especially when handled while they are still young or by having their mothers be very gentle. The meat is tasty, tender and very lean. Because yaks evolved in a high, cold climate, their fat is stored on the outside of the cacass so it can easily be trimmed off.
Yaks have small, vigorous calves with no birthing problems.
When crossed with yak bulls, first time heifers have less calving problems and stronger, more vital calves. When sold, the yak-cow crosses bring more money. Yak and yak crosses bring vigorous, very efficient animals to cattle raisers who end up with a lean, healthy meat that can command more money in the marketplace. They are easier to raise than cattle and are very intelligent, with many different personalities. If you like animals, you'll love yaks.
