This study was carried out to investigate the effect of dietary palm oil supplementation on the quality of the carcass and meat of Hanwoo (Korean cattle). Thirty-month-old steers were fed on a concentration with or without (control) palm oil for 3 mon prior to slaughter. The samples of M. longissimus were taken from all carcasses and then stored at 4℃ for 9 d. The carcass traits, total myoglobin content, pH value, total reducing ability, and myofibrillar fragmentation index were unaffected by supplementation with palm oil. However, the fat content, water-holding capacity, and tenderness were significantly increased by dietary palm oil (p<0.05). In the fatty acid composition, the palm oil group had a higher palmitic acid (C16:0) content and lower polyunsaturated fatty acids (PUFA) content compared to the control group (p<0.05). The lipid oxidation stability, myoglobin oxidation stability, and color stability were increased by dietary palm oil. It is concluded that supplemental palm oil increased the marbling and storage quality but decreased the PUFA in Hanwoo beef.
