title: [Vaccination of broilers against Newcastle disease by aerosol methods].
abstract: Tested was broiler immunization against Newcastle disease with live vaccines Hitchner B1 and La Sota after the spray method with particles of 50--100 micron and by aerosols with particles of 17--20 microns. Vaccinations were made under experiment and production conditions with chickens aged 5, 10 and 15 days. Vaccination of 5 and 10-day-old chickens was not always successful which necessitated their revaccinations. It was found that spray reimmunization with Flocks or aerosol one with Atomist enhance antibody titre and resistance degree sufficiently for prophylactic purposes. The aerosol method is more efficacious than the spray method; under production conditions it is more effective and readily applicable. Single immunization of 15-day-old chickens after both methods is effective and increases chicken immunity to the end of the fattening period.
