Iwein chickens which were immunized with attenuated vaccine of infected with virulent strain of infectious burse disease virus(IBDV)were used as experemental ob jects to study the effects of infection of IBDV on the endocrine functions in broilers by mea- suring thyroxin (T_3. T_4),adrenocorticotrophic hormone (ACTH),corticosterone (F)level in the plasma. The results showed that the chickens being immunized with attenuated vaccine could get high IBDV antibody titer, and increased plasma ACTH level;when they were in- fected with virulent strain of IBDV only increased plasma F level;the chickens being never immunized could get low IBDV antibody titer and high level of plasma T_3 and F and swollen burse when they were infected with virulent strain of IBDV.
