This study aimed to investigate the immuno - modulatory effect of a commercial probiotic (bactocell) in broiler chickens through investigating the relationship between in vitro phagocytosis by monocyte macrophage with in vivo pathogen clearance and antibody production which providing a new parameter to improve disease resistance in poultry. A total number of 260 one day old SASSO chicks were divided into 2 experiment in the study experiment 1 a total of 160 one day broiler chickens were divided into 4 equal groups G (1) chickens served as negative control G (2) chickens were fed on commercial ration supplemented with probiotic (bactocell) 1kg / ton G (3) chickens were fed on commercial ration supplemented with probiotic (bactocell) 1kg / ton and vaccinated with NDV and inactivated H5NI avian influenza (AI) vaccines G (4) chickens were vaccinated with NDV and inactivated H5NI avian influenza (AI) vaccine
