This experiment was carried out to obtain the basic data for establishing the beef carcass grade in Korea. Characteristics of beef carcass were examined by breed and sex from 1984 to 1986. The results are as follows: 1. Dressing percentage was highest in pure beef breeds (60.7%) and lowest in Holstein (57,3%). 2. K × H crossbred was highest in percentages of dressed meat and retailed cuts and Holstein in bone. Korean native cattle and pure beef breeds were higher than Holstein in trimmed fat. 3. Percentages of dressing, dressed meat and retailed cuts were lower in female than male, while bone and trimmed fat were higher in female. It appears that female cattle has lower beef productivity than male.
