Excluding bone, the loin provided the highest or second highest CD for lean or fat content of steer carcasses compared to other primals. The steer chuck appears more useful than the round or rib, except for seam fat. Less labor would be required to physically separate the loin than the chuck, but the cost of the primal would be greater. Ultimately, which primal to physically separate hinges upon resources available and information needed. Prediction of percentage lean, subcutaneous fat, seam fat and bone in the round, rib, loin and chuck of steers.
Root mean square error.
