This study was conducted to make certain that the intramuscular fat score at 13th rib could represent the fat content of whole loin from Hanwoo in Korea beef grading system. A total 42 loins from 23 carcasses of grade 1<SUP>++</SUP>, 16 carcasses of grade 1<SUP>+</SUP>, and 3 carcasses of grade 1 of Hanwoo were used for this study. The crude fat content and intramuscular fat score at the 1<SUP>st</SUP>, 6<SUP>th</SUP>, and 13<SUP>th</SUP> rib, and the last lumbar position of loin were measured. The crude fat content was the highest at the 6<SUP>th</SUP> rib of loin from the carcasses of grade 1<SUP>++</SUP> and 1<SUP>+</SUP> (p<0.05). There were no significant difference of the intramuscular fat scores measured by image analysis and beef marbling score (BMS) between the 6th and 13<SUP>th</SUP> rib of loin from the carcasses of 1<SUP>++</SUP> and 1<SUP>+</SUP> and that were significantly higher than intramuscular fat scores at the 1<SUP>st</SUP> rib and the last lumbar position of the loin. From the results, we conclude that the intramuscular fat score at the 13<SUP>th</SUP> rib can represent the fat content of loin when meat graders decide the grade of Hanwoo carcass.
