Data collected from 437 steers and 412 heifers during 9 yr were used to compare previous USDA standards (1965), the current USDA standards (1974), and the Canadian system for grading beef carcasses. Calves were sired by bulls from three breeds and raised under similar management conditions. Recorded carcass data were used to assign grades corresponding to each of the three grading systems. Previous USDA standards did not significantly affect the palatability attributes, but those carcasses receiving higher grades were fatter. The current USDA standards did not offer any significant improvement over the previous standards from the viewpoint of predicting palatability and only slight improvement as far as carcass fatness was concerned. The Canadian system, although not reflecting differences in palatability, discriminated against fatter carcasses.
