TMR feed developed by adding mugwort originating from Jeju Island,was fed to Hanwoo to investigate the effects of feeding mugwort on nutritional composition, as well as the feasibility of producing Hanwoo beef with high quality and functionality. The samples for the experiment consisted of Hanwoo fed fattening cattle TMR feed without mugwort (control), and Hanwoo fed fattening cattle TMR feed with added mugwort (treatment). Feeding mugwort did not lead to a significant difference in the moisture, crude protein, crude fat, crude ash, calorie, cholesterol, and collagen contents. There was no significant difference between the control and treatment groups in mineral components. The control and treatment groups had total mineral amounts of 3,559.20 and 3,998.01 ppm, respectively. The total amount of structural amino acids did not show any significant difference between the control (14.56%) and treatment groups (13.90%). The total amount of free amino acids did not show any significant difference between the control (763.044 ppm) and treatment groups (720.885 ppm). The composition of saturated fatty acids was 42.956% for the control and 40.918% for the treatment group. Further, the composition of unsaturated fatty acids was 57.044% for the control and 59.082% for the treatment group. Myristic acid, myristoleic acid, pentadecenoic acid, palmitic acid, and γ-linolenic acid were increased by feeding mugwort. Arachidic acid was contained the most among the fatty acid of Hanwoo fed feed without mugwort (p＜0.05)
