Abstract
Boneless beef yield and percentage of bone decreased and fat percentage increased as grade increased when Commercial, Good and Choice beef carcasses were compared. Boneless beef to bone ratio also increased in the higher grades, primarily since bone decreased markedly in higher grades. The increased boneless beef yield in lower grades cannot be attributed to a higher total yield of moist and dry heat steaks and roasts. Steers, cows and heifers, in that order, showed decreasing boneless beef and bone percentages and increasing fat percentages. The greater boneless beef yield in steers was not attributable to total of moist and dry heat steaks and roasts. Boneless beef to bone ratio was lower in steers, but similar in cows and heifers. Boneless beef yield was decreased in 800–900 lb. carcasses. Percentage fat was increased and percentage bone decreased as carcass weight increased. Light weight carcasses (400–500 lb.) showed a lower boneless beef to bone ratio; whereas the other two weight groups were similar. Copyright © . .
