Abstract
The study of the antigenic activity of vaccines used against anaerobic enterotoxemia of calves was carried out. The level of antibodies during immunization with the vaccines: «Polyvalent toxoid Clostridium perfringens against anaerobic enterotoxemia of calves» and the associated vaccine against clostridiosis «Klostbovak-8» – was comparable. Credits to all types of the pathogen was protective in the application of the toxoid. At 40–50 days of age, the level of antibodies was significantly higher when using polyvalent toxoid. No antibodies were detected in the control group.
