A bighorn ram near Jasper, Alberta. Bighorn sheep live in large herds and do not typically follow a single leader ram, unlike the mouflon, the ancestor of the domestic sheep, which has a strict dominance hierarchy. Before the mating season or "rut", the rams attempt to establish a dominance hierarchy to determine access to ewes for mating.
Farmers may also choose to focus on a particular breed of sheep in order to sell registered purebred animals, as well as provide a ram rental service for breeding.

The approach in these sheep experiments involves irradiating a ram's testes while placing stem cells from a second ram into the testes of the first, ram A. In the following weeks ram A produces semen the usual way, but is using the stem cells of ram B and therefore producing semen carrying the genetics of ram B rather than those of his own.
Social order and dominance rank is maintained in ram groups through a variety of behaviors including head-on collisions. These dramatic clashes involve each ram getting a running start before colliding, horns-first into one another. Other behaviors associated with establishing social order include leg kicks, bluff charges, and dominance mounting.
