PATHOMORPHOLOGY, DIAGNOSTICS AND SPECIFIC PREVENTION OF VIRAL RESPIRATORY AND ABOMASOENTERITIC INFECTIONS IN CALVES

Viral diseases in calves are common and often occur in associations. Pathomorphological changes in organs and tissues at viral infections allow making a preliminary nosological diagnosis and develop therapeutic and preventive measures to eliminate diseases. 
A single immunization of cows with a live-virus vaccine by the “carpet method” prevents the infection of calves in utero, and increases the safety rate of newborn calves.
