ANTIGENIC PROPERTIES OF EXPERIMENTAL SAMPLES OF INACTIVATED EMULSION VACCINE AGAINST INFECTIOUS BURSAL DISEASE
The paper provides research results on effect of antigens of different IBD virus strains in experimental samples of emulsion vaccine on dynamics and level of specifc humoral antibody induction. Some experimental samples of the emulsion vaccine from IBD virus strains «K-58», «Winterfeld-2512», «BG» and their mixture were used for the research. Chicks of three age-groups were used in experiments. Based on the research results it was determined that IBD virus strain «K-58» in the emulsion vaccine possessed the highest antigenic activity and could be used either for further research or as an antigenic component for inactivated vaccines.
