This study was conducted to investigate the influence of dietary activated carbon(0.9%) and sardine oil (0, 1, 2, 4%) on volatile basic nitrogen(VBN), thiobarbituric acid reactive substance(TBARS), and fatty acid in meat sample of chicken. Broilers were randomly assigned to one of the file dietary treatments: 1) Control(commercial feed) 2) T1(commercial feed supplemented with 0.9% activated carbon) 3) T2(commercial feed with 0.9% activated carbon and 1% sardine oil) 4) T3(commercial feed with 0.9% activated carbon and 2% sardine oil) 4) T4(commercial feed with 0.9% activated carbon and 4% sardine oil). They were fed one of the experimental diets for five weeks and slaughtered. After that, the meat samples were stored over a period of 0, 1, 3, 7 and 10 days at 41. The VBN of all treatments significantly increased during the storage periods(p<0.05). Also, the VBN was not significantly between control and treatment group. In VBN of breast was higher compared with that of thigh. The TBARS of all treatments were significantly increased as storage period extended (p<0.05). The TBARS of control and thigh tended to be higher than that of treatments and breast. Oleic acid, palmitic acid, linoleic acid, stearic acid were major fatty acid in chicken meat. Saturated fatty acid decreased and unsaturated fatty acid increased of all treatments during storage. Oleic acid, EPA, DHA contents was higher in treatment group than the control.
