FIELD: veterinary science.
SUBSTANCE: invention relates to veterinary science and is intended for producing hyperimmune serum against cattle parainfluenza-3. Studs are immunised by vaccine "Paravak" every 7 days. Vaccine is administered intranasally, 1 time 2 ml into each nostril, then subcutaneously - 3 times - 5; 6; 7 ml and intravenously - 2 times - 10; 15 ml.
