Influence of a synbiotic on some hematological and immunological parameters in broilers [electronic resource].

Includes references.

One hundred and fifty one day old chicks were grouped into five groups each of30 chicks and kept under strict hygienic and isolation measures. The first group was kept as control .The 2nd group was given synbiotic by a dose Igl5 LUres ofdrinking water for the first 3 days of age and 2 days every week during the whole experimental period . The 3rd group was given synbiotic by a dose 2g15 LUres of drinking water for the first 3 successive days and 2 days every week during the whole experimental period . The 4th group was given synbiotic by a dose of Igl5 LUres of drinking water for the first 5 successive days and 2 days every week during the whole period of experiment while the 5th group was given synbiotic by a dose 2g 15 Littre of drinking water for the first 5 successive days and 2 days every week all the period ofexperiment. On the days 28,35 and 42 of age ,blood samples were collected from all groups for haematological and immunological examinations. The result of this experiment showed non significant changes in RBCs count and Hb in all groups. Total leucocytic count, basophil ,esinophil phagocytic assay were significantly increased in groups 3,4 and 5 beside significant increase in heterophil in group 5 only . Synbiotic administration elicited significant increase in body weight. The results also showed Significant increase in bursal weight in all groups while thymus weight was increased in group 4 only It could be concluded that synbiotic administration produced a favorable effects on immunological parameters and growth performance of broiler chickens.
