THE PURPOSE OF SHEEP BREEDING

Sheep are mainly raised for the purpose of obtaining pelts and wool clothing and carpets. The quality and the market value of wool vary greatly with the fineness, curliness and lightness as well as the length of the fibre it consists of. Moreover, the wool is light in relation to its value and is relatively imperishable, both of which qualities have made it a valuable item of trade and export. In addition to providing wool, sheep produce meat in the form of lamb and mutton, and milk for drinking and cheese-making. Sheep can be used to a small extent as pack-animals. Recently, sheep-raising in some areas has decreased in favour of more profitable cattle.

Sheep bred for their fine wool account for nearly half the world sheep population. They are adapted to semiarid conditions and are characterized as medium in size, with the ability to produce large amounts of wool fibres 20 micrometers or less in diameter. Most sheep of this type belong to the Merino breed. The other major breed of fine-wool sheep is Rambouillet, which is similar to the Merino.

Commercial sheep today represent two-breed or three-breed crosses, with white-faced crossbred ewes preferred in the range areas and a black-faced sire, such as Suffolk or Hampshire, preferred for market lambs, which are either finished for slaughter or sold as breeding ewes.
