Development of associated vaccine against Piv-3, Ibr, Bvd and chlamidiosis of cattle

Abstract

As a result of clinical and epizootological examination of dysfunctional farms with respiratory and intestinal infections, the main agents of pneumoenteritis of calves and based on this we developed and associated inactivated vaccine against PIV-3, IBR, BVD and chlamidiosis were identified. The results of laboratory and production tests showed that it has high antigenic activity and immunogenic properties for laboratory animals, and its use in dysfunctional farms reduces the incidence of young animals, increases their birth rate and safety which has a positive effect on the efficiency of cattle breeding.
