Abstract | ||||
Baby chicks in native hatcheries were immunized with the "F, B1 and laSota" vaccines of Newcastle disease virus by the ocular, spray and head dipping methods. Immune response was monitored by challenge and haemagglutination-inhibition tests. High level of immunity lasting up to 5 weeks developed after vaccination with the B, and LaSota strains by the intraocular route. A low grade levels of immunity developed after the head dipping method. | ||||
