Effects of some Growth Promoters on Blood Hematology and Serum Composition of Broiler Chickens

S. Al-Saad, M. Abbod and A. Abo Yones
This study was designed to compare the effects of antibiotic, probiotic, prebiotic and organic acid supplements on the hematological and biochemical constituents of blood of broiler chickens. The 450 broiler chickens of the commercial Hubbard Flex strain were used in a randomized completely design with 5 groups, 3 replicates in each group and 30 birds replicates. Birds were raised on floor pens for 42 days. Group (1) Basal diet with no additives (control), group (2) Basal diet+100 g ton-1 antibiotic (lincomaycin), group (3) Basal diet+1000 g ton-1 probiotic (Bacillus subtilis spp), group (4) Basal diet+1000 g ton-1 prebiotic (Mannan oligosaccharide MOS) and group (5) Basal diet+1000 g ton-1 organic acid (sorbic acid, propionic acid, benzoic acid, phosphoric acid). On day 42 of the experiment, two birds from each replicate were selected and the blood samples were taken from the wing artery to determine some blood indicators. The results showed that there was no significant differences (p>0.05) in the Red Blood Cells (RBC) number and blood hemoglobin of birds in all groups. Significant increase in number of White Blood Cells (WBC) in blood samples of probiotic and organic acids groups compared to antibiotic group, significant increase was obvious in the HCT % of the group fed on probiotic compared to the other groups (p<0.05). There was no significant difference in blood glucose levels between all groups, a decrease in the blood level of total cholesterol and triglyceride was observed in groups fed on probiotic and organic acids compared to other groups. A significant increase was also observed (p<0.05) in HDL cholesterol level in groups fed on probiotic and prebiotic and a significant decrease (p<0.05) in LDL cholesterol level in the same groups as compared with the other groups.
