Polyvalent clostridial vaccine has been prepared according to L+ dose of C. perfringens type B and D, C. septicum, C. oedematiens, the optical density of C. chauvoei, and flocculation test of C. tetani. The vaccine has been evaluated in guinea pigs, rabbits and sheep. It gave high protective immunity in guinea pigs in challenge test (100% protection), the sera of vaccinated rabbits gave high titers more than the permissible limit. Sera of vaccinated sheep showed high antibody titer and good immune response which revealed that the vaccine able to protect sheep against clostridial diseases. The recent formulation of polyvalent clostridial vaccine is very useful tool for production of highly antigenic multicomponent clostridial vaccine used for control of different clostridial diseases.
