Most other countries' beef grading systems mirror the U.S. model, except for those in the European Union (EU). The EU employs a grading scheme that emphasizes carcass shape and amount of fat covering [4] instead of marbling and aging. The differences in grading yield incompatible value judgments of beef value in the United States and the EU. [5]
During butchering, beef is first divided into primal cuts, pieces of meat initially separated from the carcass. These are basic sections from which steaks and other subdivisions are cut. Since the animal's legs and neck muscles do the most work, they are the toughest; the meat becomes more tender as distance from hoof and horn increases.
A carcass grade is an assessment of quality for a culled cow or bull. The various grades are defined by the United States Department of Agriculture, and assessments are based primarily on the fatness of the cow to be culled. [1] Cows are culled from herds for a variety of reasons, including poor production, age, or health problems. [2]

The left is the natural color view of the cut; the right is the instrument enhanced view that details the amount of marbling, size, and fat thickness. Optical sorting achieves non-destructive, 100 percent inspection in-line at full production volumes.
There is a range of types of feed available for these animals. The standard text in the United States, Nutrient Requirements of Beef Cattle, has been through eight editions over at least seventy years. [9] The 1996 seventh edition substituted the concept of metabolizeable protein for the sixth edition's crude protein.

Beef quality grades - are based on a composite evaluation of the degrees of (1) marbling and (2) maturity. [1] These designations reflect carcass firmness, texture, and color of lean, and the amount and distribution of marbling within the lean. High grades represent high projected levels of tenderness, juiciness, and flavor.
