Sheep were among the first species of animals to be domesticated. They provide meat for food and wool and sheepskin for clothing and shelter. Today, sheep are used for their meat, wool and milk. Many popular cheeses like feta, ricotta, romano and Roquefort are made using sheep milk and are commonly imported to the U.S. from France, Greece, Italy and Spain. Cosmetics, lubricants, piano keys and many other types of by-products are made from sheep.

Like other types of livestock, there are many different breeds of sheep, all with different characteristics and traits. Some breeds are known for high milk production or the wool they produce. Depending on the breed, sheep vary in height and weight. Female sheep, called ewes, typically weigh between 99 and 220 pounds. Rams, male sheep used for breeding, can weigh up to 350 pounds.

Ewes are usually bred in the fall and give birth in the late winter and early spring. Lambs are sold to market when they reach between 115 and 140 pounds, which is approximately four to seven months of age. Like cattle, sheep are ruminants, which means they have four compartments in their stomach. Sheep do not have any upper front teeth. When eating forages, such as grass and alfalfa, they close the lower teeth against the dental pad of the upper jaw.
