Expression of IFN-γ gene in the intestine and cecal tonsils of Clostridium perfringens (CP)-challenged broiler chickens. Treatment 1 (CX) consisted of unchallenged chicks fed corn-soybean meal (SBM) basal only; treatment 2 (CM) consisted of unchallenged chicks fed corn-SBM basal into which bacitracin methylene disalicylate antibiotic was supplemented at 0.055 g/kg diet; treatments 3 (PCX) and 4 (PCM) consisted of chicks challenged with CP on 3 consecutive days (day 14, 15, and 16), and fed diets similar to those given to chicks treatments 1 and 2, respectively. Bars with different letters within each figure differ significantly (P < 0.05).
