400 one day-old broiler chicks were allocated on a randomized complete design experiment with five treatments consisting of four replications for 42 days. Experiment treatments were included: 1 . based diet consist 20 percent barley (barley control), 2 . barley control + 0.1 percent of mixed essential oil (Antibiofin), 3 . barley control + 0.2 percent organic acid, 4 . barley control + 15 ppm of antibiotic (virginiamycin) and 5 . corn-soybean based diet as corn control. In addition, Basal diet supplemented with commercial enzyme preparation. There was significant difference within treatments for 42 age's body weight and FCR. No significant differences in FI were noted among treatment during experiment. Antibody titer against (SRBC) among groups in secondly immuno response had a significant effect (P< 0.05). The villus height of deudenum and Jejunum was significant differences among the treatment groups. It can be concluded that by using additives such as medicinal plant and organic acids in diets containing barley, can be achieved to similar performance of corn based diets.
