홀스타인 거세육우의 출하시기에 따른 채끝, 꾸리, 홍두깨육의 이화학적 육질특성 및 지방산조성

This study was performed to investigate the physicochemical properties of striploin (m. longissimus dorsi), chuck tender (m. supraspinatus) and eye of round (m. semitendinosus) of Holstein steer beef produced from different fattening groups (18, 21, 24 mon-old). The intramuscular fat contents were significantly higher in striploin (9.14%) and eye of round (4.31%) from 24 mon-old groups when compared to the same cuts (6.53% and 2.63%) from 18 mon-old groups, respectively. Three muscles from 18 mon-old group had significantly higher moisture contents (%) than those from the other groups (p<0.05).
