Fat-tailed sheep

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's sheep population, and are commonly found in northern parts of Africa, the Middle East, and various Central Asian countries all the way to China. The tail fat from those sheep is an important ingredient in many regional cuisines. Two general varieties of fat-tails exist, the broad fat-tails and the long fat-tails. The long-tailed varieties have the smallest geographical distribution, being found mostly in Arabia (a variety called the Nejd, black with a white head, named for the Nejd region, and raised also in Iraq, Central Asia, and Syria) and in the Caucasus (the Colchian, for the Colchis territory, and the Circassian). Broad varieties include the Hajaz (Arabia, small and white, named for the Hejaz region), the Arabi (black or piebald, in Arabia and Iraq), the Awassi (the dominant variety in Iraq, Lebanon, Syria, Palestine, Jordan), and the ak or White Karaman (in Turkey). Eastward, toward Iran (among the Bakhtiari people) and China, there are dozens of varieties, including the Karakul. Fat-tailed sheep likely moved into Africa through the Horn of Africa, then into Egypt and North Africa, at least by 2000 BC, when they are depicted in Egyptian art. They were the third type of sheep to be brought into Africa. The majority of fat-tailed sheep breeds have broad fat-tails, where the fat is accumulated in baggy deposits in the hind parts of a sheep on both sides of its tail and on the first 3–5 vertebrae of the tail. Earlier historians including Herodotus report that their tails sometimes were so long that shepherds built miniature carts for them, and that tails sometimes grew so large that it dragged on the ground and hindered copulation. Fat-tailed sheep are well adapted to life in arid landscapes, the fat providing a food reserve for "combatting harsh desert conditions". The earliest record of fat-tailed sheep is found in ancient Uruk (3000 BC) and Ur (2400 BC) on stone vessels and mosaics.
