Specific immunoprophylaxis of some viral diseases in cattle.

ABSTRACT

Specific immunoprophylaxis has played a key role in prevention and control of animal infectious diseases for many years. Vaccines are commonly used to diminish economic losses in animal production caused by infectious agents. Currently, respiratory diseases are the main health problem in cattle. BHV1, BRSV and BVD-MD viruses are among the most important pathogens worldwide. They can cause a disease themselves or they can be one of many agents causing a respiratory syndrome. The following article describes the specific immunoprophylaxis of cattle viral diseases caused by such viruses.
