Abstract
The effect of BDV and ROV challenge on RD immunity was studied
on 30 IR-2 broiler chicks. It was found that those birds which were
vaccinated with RDV-F on 7th day intranasally and chaIlenged on 30th
day showed a survival rate of 40% while those birds vaccinated with RDVF
on 7th day intranasally and challenged 50th day showed a still lower
survival rate of30%, inspite of high HI titres and ELISA values. This could
be suggestive of immunosuppression against RD consequent to IBD
challenge.
