Abstract :This study was amid to evaluate the effect of supplementation of oxytetracylin (OTC), probiotic (Pro.), and citric acid (CA) separately on growth rate hematological, intestinal microflora and morphology of broiler chickens. A total of 270 one- day old male broiler chickens (Ross 308), were randomly kept into six groups floor pens consisting 3 replicates of 15 birds each. Treatment were as following: T 1 (control diet without supplement), T2 supplementing with OTC (0.5 g/ kg); T 3 and T 4 supplementing with CA (1.0 or 1.5 g/ kg diet respectively), T 5 and T 6 supplementing with CA (1.0 or 1.5 g/ kg diet respectively). The results showed, there were significant increase in weight gain in broilers fed T 3 and T 4 dietary treatments, and no significant difference between the other treatments. Significant decrease in RBC, PCV and Hb, while increased in WBC, Lymphocytes, ALT and AST in birds supplemented with T 2 dietary treatment. The diet containing OTC T 2 and CA T 6 caused reduced in micoflora count in jejunum area. There was significant increase in villi height and crypt depth for T 6 while there was significant decrease in T 2 . In conclusion, probiotic and citric acid are good alternative to antibiotics in promoting growth, and beneficial modulation of intestinal micoflora and improve intestinal morphology.Keywords : Broiler, Oxytetracylin, Probiotic and citric acid, Hematology, Morphology
