Sheep are domestic animals raised on farms for their wool, meat and milk. Along with goats, pigs and cattle, sheep were among the first animals to be domesticated.

Wool sheep are classified as Ovis aries aries. Merino, Rambouillet, Blue Faced Leicester, and Corriedale breeds are among the best-known wool sheep.

There are hundreds of sheep breeds …

Some sheep breeds are raised for their meat, others for their wool, others for both. The Texel and Dorset breeds are good choices for meat production. But there are literally hundreds of sheep breeds.

All wool can be used

Wool can be used for different purposes, depending on the coarseness of the fibre and on other characteristics such as fibre length and crimp. Very fine wool is primarily used for clothing while coarser wool is used in carpets and furnishings such as curtains or bedding.
