EFFECTS OF VARIOUS APPLICATION ROUTES OF NEWCASTLE DISEASE VACCINE ON SPECIFIC ANTIBODY TITRES IN OSTRICHES

摘要

Newcastle disease (ND) is one of the most important diseases of poultry and other avian species. The usual mean to control ND is specific immunoprophylaxis. Although chickens are routinely vaccinated against ND, vaccination of ostriches is less well understood. We investigated the effect of vaccination against Newcastle disease via different routes on specific antibody liter In 24 adult ostriches, divided into three experimental and one control group. The vaccine was administered in drinking water tothe first, by spraying to the second, and oculo-nasally to the third group. The results have indicated antibody production with liters sufficient for humoral immunity in all experimental groups. The strongest immune response was determined in the groupvaccinated by spraying.
