In many countries inactivated vaccines to prevent Colibacilosis and atrophic rhinitis in pigs, are implemented during the sow gestation period. In Brasil Atrophic Rhinitis is an endemic and chronic disease, therefore most of the farms are vaccinating against this disease and against colibacilosis at the same time. This study show the safety in use of a mixture of SUISENG® (vaccine against the Neonatal Piglet Colibacillosis, C. perfringens and C. novyi enterotoxicosis) and RHINISENG® (Atrophic rhinitis vaccine) vaccines, inactivated vaccines against Colibacilosis-Clostridiosis and Atrophic rhinitis respectively.
