Purebred Barki is the breed of choice for Bedouins in the desert. All are fat-tailed sheep. What distinguishes fat-tailed sheep from other sheep is their long tails, filled with fat and having a function similar to the camel's hump. Fat-tailed sheep are hardy and adaptable, able to withstand the tough challenges of desert life. When feed is ample and parasites not burdensome, fat-tailed sheep can be impressive in size, growth, and conformation.
Carcass quality is good, with most of the fat concentrated in the tail region.
The carcass and meat are preferred by Moslems. The wool from fat-tailed breeds is coarse and frequently has colored fibers. It would be of limited value in world markets. It is used primarily for rug making and other cottage-type industries. Some shepherds sell their wool clip, while others give it away to the shearer.
