After the steer is slaughtered, it is cut into four pieces (called quarters) for easy handling. This is done by first splitting the carcass down the backbone into two bilateral halves. Each half is divided into the forequarter (the front portion) and hindquarter (the rear portion) by cutting along the natural curvature between the 12th and 13th ribs. The quartered carcass is then further reduced into the primal cuts and the sub primal and fabricated cuts. The primal cuts of beef are the chuck, brisket and shank, rib, short plate, short loin, sirloin, flank and round. It is important to know the location of bones when cutting or working with meats. This makes meat fabrication and carving easier and aids in identifying cuts. An entire beef carcass can range in weight from 500 to more than 800 pounds (225-360 kg).
