In this study experimental infection with CIAV was performed on one and seven days old broiler chickens from naturally infected parent flock during the rearing period. In infected birds, clinical signs, hematological findings and humoral immune response were examined. In all one and seven days old chickens maternally derived antibodies were established. No clinical signs of chicken infectious anemia (CIA) were observed, hematological findings showed no deviation from referent values and there were no specific pathomorphological and histopathological changes at post-mortem examination. According to previous knowledge, only serological negative flock if infected in time of laying represent risk for vertical transmission to progeny where typical disease with mortality will apear. The absence of Mabs in one old chickens is critical point in break of disease. Typical clinical picture in day old chickens rises only when vertical transmission occurs.
