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: T1 (control diet without supplement), T2
supplementing with OTC (0.5 g/ kg); T3 and T4
supplementing with CA (1.0 or 1.5 g/ kg diet respectively), T5 and T6
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 T3
and T4 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 T2 dietary
treatment. The diet containing OTC T2 and CA T6 caused
reduced in micoflora count in jejunum area. There was significant increase in
villi height and crypt depth for T6 while there was significant
decrease in T2. In conclusion, probiotic and citric acid are good
alternative to antibiotics in promoting growth, and beneficial modulation of
intestinal micoflora and improve intestinal morphology.
