Excerpts from the report: The purpose of this study was to survey the grade consist of the fed beef population. The data were collected under the grade standards in effect in 1973 and 1974, and most of the results reported reflect these standards. However, the last four tables showing results reflect the effect of the grade changes which became effective in February 1976. Information collected on each carcass included the quality grade factors (conformation, maturity, and marbling); the final quality grade; the yield grade factors (carcass weight, actual and adjusted fat over the ribeye, ribeye area, and estimated percentage kidney, pelvic, and heart fat); and the yield grade. In addition, the class of the carcasses (steer, heifer, or bullock) and comments of the evaluators concerning dark cutters, unusual conditions, or any other factors which affected the grades of particular carcasses were recorded.
