Cut of beef. Cuts of beef are first divided into primal cuts, pieces of meat initially separated from the carcass during butchering. These are basic sections from which steaks and other subdivisions are cut. The term primal cut is quite different from prime cut, used to characterize cuts considered to be of higher quality.
Steaks are also cut from grazing animals, usually farmed, other than cattle, including bison, camel, goat, horse, kangaroo, sheep, ostrich, pigs, reindeer, turkey and deer, as well as various types of fish, especially salmon. Some cured meat, such as gammon, is commonly served as steak.
