TMR feed was developed by adding mugwort (Artemisia capillaris), and was fed to Hanwoo cattle to investigate the effects of feeding mugwort on the physicochemical and sensory characteristics of rump meat, and to determine the feasibility of producing Hanwoo beef with high quality and functionality. The experimental samples consisted of the Hanwoo rump from cattle fed with fattening TMR feed without mugwort (T0), and those fed with fattening cattle TMR feed supplemented with mugwort (T1). T1 was significantly higher than T0 for Hanwoo rump characteristics of Hunter's $L^*$, $a^*$, $b^*$ values (p<0.05). VBN content for T0 was significantly higher than for T1, and EDA for T1 was significantly higher than for T0 (p<0.05). There was no significant difference between T0 and T1 in terms of pH, TBARS, and total bacterial numbers. Water holding capacity for T1 was significantly higher than for T0 (p<0.05), but there was no significant difference between T0 and T1 in terms of freezing loss, thawing loss, and cooking loss. Springiness for T1 was significantly higher than for T0 (p<0.05), and there was no significant difference between T0 and T1 in terms of hardness, cohesiveness, gumminess, chewiness, and shear force. There was no significant difference between T0 and T1 in terms of acid value, peroxide value, and iodine value. However, the melting point for T1 was significantly lower than for T0 (p<0.05). Aroma of raw meat for T1 was significantly superior to aroma for T0 (p<0.05). Taste, palatability of boiled meat, and juiciness of roasted meat for T1 were significantly superior to those parameters for T0 (p<0.05). These results suggest that the feed containing mugwort can be used to improve color and sensory characteristics, inhibit VBN formation, and also to increase antioxidant ability as a functional feed. 본 연구는 인진쑥을 일정량 첨가한 TMR 사료를 개발하여, 이를 한우에게 급여한 경우, 인진쑥의 급여가 한우 우둔부위의 이화학적 및 관능특성에 미치는 영향에 관한 연구를 통하여 고급화된 기능성 한우의 생산 가능성을 검토하였다. 대조군(T0)은 인진쑥을 혼합하지 않은 비육우 사료를 급여하였고, 급여군(T1)은 비육우 사료에 인진쑥을 혼합한 TMR 사료를 급여하였다. Hunter's $L^*$, $a^*$ 및 $b^*$ 값은 T1이 T0보다 유의하게 높았다(p<0.05). VBN 함랑은 T0가 T1보다 유의하게 높고, 전자공여능은 T1이 T0보다 유의하게 높았으나, pH, TBARS 및 총균수는 T0 및 T1 사이에 유의한 차이가 없었다(p<0.05). 보수력은 T1이 T0보다 유의하게 높았지만, 동결감량, 해동 감량 및 가열 감량은 T0 및 T1 사이에 유의한 차이가 없었다(p<0.05). 탄성은 T1이 T0보다 유의하게 높았으며, 경도, 응집성, 뭉침성, 저작성 및 전단력은 T0 및 T1 사이에 유의한 차이가 없었다(p<0.05). 산가, 과산화물가 및 요오드가는 T0 및 T1 사이에 유의한 차이가 없었으나, 융점은 T0가 T1보다 유의하게 높았다. 생육의 냄새는 T1 이 T0보다 유의하게 우수하였다(p<0.05). 열탕 가열육의 맛과 전체적인 기호성, 팬 가열육의 다즙성은 T1이 T0보다 우수하였다. 결론적으로 인진쑥의 급여는 한우 우둔부위의 색깔 개선, VBN 생성 억제, 항산화력 증가, 관능 특성을 개선하는 효과가 있어서 기능성 사료의 소재로서의 이용이 기대된다.
