Bighorn Ram
You can find the bighorn ram in desert areas ranging from Nevada and California to Texas and Mexico. These rams can weigh up to 280 lb., be more than 5 feet long and be more than 3 feet tall at the shoulder. They generally eat grasses, sedges and forbs, but in the winter, they will also eat things like twigs, leaves and shoots. The rams' head-to-head combats can last up to 24 hours, and are for the right to mate with a particular ewe rather than for territory. Bighorn rams usually live for about 10 to 15 years.
Sudan Desert Ram
The Sudan desert ram is the result of the Sudanese tribes crossbreeding their own types of sheep in order to have a breed of sheep that could live in the harsh conditions of the Sudan desert. The rams of this breed are almost identical to the ewes, except that some do not have horns, and all rams have a thick neck that has a dewlap that extends from their chin to their brisket. A Sudan desert ram's horns can vary from being bud-sized to being large, in which case they extend almost entirely horizontally from the ram's head. These rams can live for approximately seven years.
Fulani Ram
The Fulani ram is one of the breeds originally used in the crossbreeding process that created the Sudan desert ram; in fact, the Fulani ram is one of the breeds that had the hardy characteristics that breeders sought. These sheep also have the distinction of being known under many different names: Ara-Ara, Balami, Fulani long-legged, Peul-Peul, Toronké, Uda and Yankasa. Fulani rams can grow to be approximately 117 lb., and have horns that can grow more than 2 feet.
Painted Desert Ram
The painted desert ram is also the product of selective breeding, initially to create a kind of sheep that produced a finer quality of wool. As of 2011, however, these sheep are bred for the quality of their horns, which grow horizontally from the head, but curl in the process. True to their name, painted desert rams have mottled coats that can resemble the classic dairy cow pattern.
