A baby sheep is called a lamb. A lamb is defined as a sheep that is less than 14 months old. Adult sheep are called rams if they are male and ewes if they are female.
Sheep are raised by farmers for their meat (lamb and mutton), wool and milk. In addition, sheep fat has been used to make wax and candles. There is evidence that humans have been using wool from sheep as far back as 10,000 B.C. Sheep can be found throughout the United States with the highest numbers in the states of Wyoming, Texas and California. However, the largest world exporters of lamb and mutton are Australia and New Zealand.
