Abstract
The study was carried out to assesst the protective immune ef cacy of E.acervulina oocyst protein against homologous challenge in chickens. Immunization was applied on 14th and 18th day of age subcutaneously with that protein at dose of 50 μg per chicken. Immunized chickens were challenged at 32nd day of age, demonstrated that oocyst protein could provide protection around 62% when compared with unimmunized chickens, while parasite development in intestine asses in histological section revealed decreased proliferation. The study results demonstrated that relatively suf cient protection against coccidia by the use ofE. Acervulina oocyst protein as vaccine in broilers
Key Words: E.acervulina, oocyst protein, protective immunity
