Indices of Immune Responses of Bulls in the Necrobacillosis Vaccination of the Cattle

Abstract

Metabolic disorders and dysfunctional state of the digestive organs lead to the development of distal extremities diseases. The greatest danger is neсrobacrillosis. Vaccination is one of the ways to prevent and control this disease. The article reflects the data on the effect of vaccination (“Nekovak” and formol-emulsion neсrobacrillosis vaccine of Federal Centre for toxicology, radiation and biological safety) on immunological and serological parameters of blood and blood serum of cattle in the Udmurt Republic. After immunization with “Nekovak” vaccine and formol-emulsion neсrobacrillosis vaccine, we determined an increase of the number of leukocytes to 7th day, and also an increase of T-lymphocytes to 14th day. The number of B-lymphocytes reaches a maximum on 21st day. The content of gamma globulins, including specific antibodies against the neсrobacrillosis pathogen, exceeded the control and reached a maximum on the 21st day after vaccination.
