| Abstract |
|
The study was aimed at
evaluating the comparative efficacy of Newcastle
disease vaccine (NDV), produced locally in
Nigeria
by National Veterinary Research Institute (NVM) Jos
Plateau State, Nigeria,
in controlling the Newcastle
disease using oral and intraocular routes. The morphological changes and
the immune response of the lymphoid organs (accessory lacrimal gland and
bursa of fabricious) were studied. The lymphoid organs on histopathology
did not show many changes in vaccinated chickens with
Newcastle
disease vaccine, administered intraocular but produced marked changes in
birds subjected to drinking water. The marked high number of plasma cell
observed in intraocular vaccinated birds was indicative that this route
was more effective than drinking water.
