Carcass grade
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.
Cows are culled from herds for a variety of reasons, including poor production, age, or health problems. A carcass grade (or expected carcass grade) is used to determine selling prices for cull cows, which are estimated to comprise 20% of the beef available to consumers in the United States.
