This study was conducted to investigate the effect of dietary Panax ginseng Leaves, (PGL), Dioscorea japonica Hulls(DJH) and Oriental Medicine Refuse(OMR) on meat quality and physico-chemical properties in meat sample of Korean Native Chicken(KNC). KNC were randomly assigned to one of the 4 dietary treatment : 1) control(commercial feed), 2) PGL(commercial feed supplemented with 5% Panax ginseng leaves) 3) DJH(commercial feed with 5% Dioscorea japonica hulls) 4) OMR (commercial feed with 5% oriental medicine refuse). They were feed one of the experimental diets for 12 weeks and slaughtered. 160 KNC raised for 20 weeks. In the proximate composition, moisture, crude protein and crude ash was no significantly difference. But fat content were tended to high in control. The heating loss of control, PGL, DJH and OMR were 28.44%, 30.44%, 28.83% and 25.71% and control, PGL, and DJH were higher compared with that of OMR. The WHC(water holding capacity) was contrary to heating loss. The shear value and pH did not show any difference among the treatment groups. There were no significantly different in meat color(L^＊, a^＊, b^＊) between control and treatment groups (L^＊=63.20∼70.67, a^＊=2.20∼4.15, b^＊=2.70∼6.01). In sensory evaluation, juiciness, tenderness and flavor were not detected to panelist. Among fatty acid, oleic acid of DJH and OMR were higher than that of control and PGL(pOMR>DJH>PGL. Major amino acid of KNC was composed to glutamic acid, lysine, aspartic acid, leucine and arginine.
