This vaccine efficacy was tested and compare to a similar commercial vaccine in hybro layer chicken against challenge with virulent field and reference strain. The anti body response in both vaccinated chickens were measured by Elisa technique. The result from this study showed that there was no significant difference (P=0,147) in the mean antibody level detected by Elisa between the trivalent field isolate and a commercial vaccine. However the trivalent field isolate vaccine produced slightly better protection against challenge with virulent field isolate.
