Indicates whether the cut is pork, beef, lamb, veal, etc.

Known as the primal or wholesale cut, this specifies what part of the animal the meat came from (shoulder, loin, leg, etc.) This information can help you determined how tender the meat will be and how it should be prepared.
What is the Retail Cut?
The smaller cut taken from the primal cut (rib chop, sirloin roast, etc.)
