TMR (total mixed ration) feed was developed by adding mugwort and was fed to Korean black cattle. The effects on the physicochemical properties of the Korean black cattle, when fed mugwort, were investigated, as was the feasibility of producing beef with high quality and functionality. Korean black cattle were reared by using basal TMR (control) and basal TMR supplemented with mugwort of middle fattening 4.6% and late fattening 6.5% (treatment). The content of total catechin in Korean black cattle fed with the control and treatment was 0.262 and 0.379 mg/kg, respectively, while the content of epicatechin was 0.042 and 0.059 mg/kg, respectively, both of which were a significant increase from feeding the cattle TMR with mugwort (p <0.05). There was no significant difference between the control and treatment in terms of L* (lightness), b* (yellowness), pH, VBN (volatile basic nitrogen) content, bacterial counts, water-holding capacity, freezing loss, thawing loss, cooking loss, cohesiveness, chewiness, shear force, and sensory score. TBARS (2-thiobarbituric acid reactive substances) and springiness for the control were significantly higher than the treatment (p <0.05). The a* (redness), EDA (electron donating ability), hardness, and gumminess for the treatment were significantly higher than for the control (p <0.05). These results suggest that the feed containing mugwort can be used to improve color and increase antioxidant ability as functional feed.
