Fat-tailed breed

The fat-tailed sheep is a general type of domestic sheep known for their distinctive large tails and hindquarters. Fat-tailed sheep breeds comprise approximately 25% of the world sheep population, and are commonly found in northern parts of Africa, the Middle East, Pakistan, Afghanistan, Iran, North India, Western China, Somaliaand Central Asia.

The earliest record of this sheep variety is found in ancient Uruk (3000 BC) and Ur (2400 BC) on stone vessels and mosaics. Another early reference is found in the Bible (Leviticus 3:9), where a sacrificial offering is described which includes the tail fat of sheep.

Sheep were specifically bred for the unique quality of the fat stored in the tail area and the fat (called Elyah, Arabic: ألية ) was used extensively in medieval Arab and Persian cookery. The tail fat is still used in modern cookery, though there has been a reported decline, with other types of fat and oils having increased in popularity.

Fat-tailed sheep are hardy and adaptable, able to withstand the tough challenges of desert life. When feed is plentiful and parasites not a major factor, fat-tailed sheep can be large in size and growth. The carcass quality of these sheep is quite good, with most of the fat concentrated in the tail area - it could account for as much as 10 pounds (4.5 kilograms) of the weight on a 60 pound (27 kilogram) carcass. The fat-tailed breeds seen frequently in the US are the Karakul and Tunis.
