Sheep have been milked for thousands of years, perhaps before any other animal. The dairy sheep industry is highly developed in many countries, especially in and around the Mediterranean. In the United States, sheep dairying is a small part of a small industry. Most U.S. sheep dairies are located in Wisconsin and the New England states. At the same time, there are sheep dairies in many other states, and the interest in sheep dairying seems to be on the rise.
