Abstract   

    A total of 160 one-day-old broiler chicks were used to evaluate the immunomodulatory effects of an inactivated Eimeria tenella vaccine and a live polyvalent imported antiococcidial vaccine (Coccivac). This study indicated that both of these vaccines did not adversely affect the development of serum antibody against Newcastle disease virus (NDV) and the chicks vaccinated with either of the anticoccidial vaccines resisted the virulent NDV challenge. A study of the lymphoid organs such as bursa of fabricuis: thymus and spleen from the experimental chicks indicated that those organs were comparable with those from the chicks not vaccinated with these coccidial vaccines. The overall findings of this study indicate that anticoccidial vaccines do not have any effects on the immune functions of the vaccinates. In fact these vaccines prevented the occurrence of clinical coccidiosis in the vaccinates.    

Key words: Immuno-Modulatory, Eimeria tenella, Newcastle Disease Virus.
