This study was conducted to estimate the effects of high quality cubed roughage and red clay (0%, 1%, 2%) on growth performance, meat quality and economical benefits. Thirty-six 6 month-old Korean native cattle, averaging 156kg of BW, were assigned to six groups in a 2 (rice straw : RT, rice straw+cubed roughage : RCT) ${\times}$ 3 (0, 1, 2% red clay). During experimental period, the high quality cubed roughage added into rice straw treatment (RCT) was superior to the only rice straw treatment (RT) on daily gain and feed efficiency and final weight 10%, 6.8%, 8.2% (P$<$0.05) respectively. But the addition of red clay did not affect and even 2% addition decreased those parameters. For meat quality and economical analysis, the addition of high quality cubed roughage made an outstanding result and for RT treatment, only 1% red clay indicated good effects while both 1% and 2% red clay were better than 0% for RCT treatment. From these results, it is assumed that the addition of red clay for fattening Korean native cattle has no effects on growth performance but 1% treatment has good results on improving meat quality and economical benefits. It also suggests that the combination high quality roughage and concentrated red clay is beneficial for producing high quality meat in with economical benefits.
