This experiment was conducted to investigate the effect of feeding TMR with or without Yukmijihwangtang meal silage on the growth performance, meat yield and quality of Hanwoo steers. Sixteen male Hanwoo steers in the late fattening period were randomly assigned to a control diet and Yukmijihwangtang meal diet, with eight heads per treatment. The supplementation of Yukmijihwangtang meal silage did not affect the feed conversion rate, ribeye area, and meat yield index of cold carcass of Hanwoo. Fat thickness of Hanwoo s loin obtained from silage supplementation was significantly lower than that of non-supplemented. Total grade in meat yield of Hanwoo from silage supplementation were higher than that of non-supplemented control. The supplementation of Yukmijihwangtang meal silage to Hanwoo decreased the marbling score significantly, but did not affect fat color, firmness, and maturity. Total grade of meat quality of Hanwoo with Yukmijihwangtang meal supplementation was lower than that of non-supplemented control. In conclusion, Yukmijihwangtang meal could be used as partial substitution (10%) in TMR for fattening cattle. However, it is considered that Yukmijihwangtang meal can be a useful feed for the periods of growing or early fattening than that of late fattening since it improved meat yield but decreased meat quality grade of Hanwoo steers.
