Bighorn sheep are named for the large, curved horns borne by the rams (males). Ewes (females) also have horns, but they are shorter and straighter. [20] They range in color from light brown to grayish or dark, chocolate brown, with a white rump and lining on the backs of all four legs.
Rams' horns may be very large – those of a mature bighorn ram can weigh 14 kg (31 lb) – as much as the bones of the rest of its body put together. Rams use their horns to fight with each other for dominance and the right to mate with females. In most cases, they do not injure each other because they hit each other head-to-head, and their ...
After eight years of growth, the horns of an adult ram may weigh more than 30 pounds. [7] Annual growth rings indicate the animal's age. The rams may rub their own horns to improve their field of view. [7] Both rams and ewes use their horns as tools to break open cactus, which they consume, and for fighting. [8]

Horns start to grow soon after birth and continue to grow throughout the life of the animal (except in pronghorns, which shed the outer layer annually, but retain the bony core). Partial or deformed horns in livestock are called scurs.
Arguments against dehorning include the following: Dehorning (removing fully grown horns) without the use of anesthesia is extremely painful to the animal.

Rams have larger horns than ewes. The horns in two-horned sheep, and the lower horns in four-horned animals, grow in a spiral shape. The rostral set of horns usually extend upwards and outwards, while the caudal set of horns curls downwards along the side of the head and neck. On polycerate animals it is preferred that there is a fleshy gap ...
