METHOD FOR IMMUNOPROPHYLAXIS OF ACUTE RESPIRATORY DISEASES IN CALVES Russian patent published in 2007 - IPC A61K39/295 A61K39/265 A61K39/155 A61K47/38 

FIELD: veterinary science.

SUBSTANCE: one should carry out immunization in down-calving cows with dry culture associated alive vaccine against paragrippe-3 and infectious rhinotracheitis in cattle at the dosage of 2 ml 1.5 mo before calving and simultaneously it is necessary to inject ligavirin subcutaneously at the dosage of 5 ml. In 14 d one should introduce ligavirin once more at the same dosage. Calves born in these cows should be once injected with ligavirin intramuscularly during 0.5-1 h after calving at the dosage of 1 ml. The innovation enables to increase efficiency of immunoprophylaxis of viral respiratory diseases in calves.

EFFECT: higher efficiency of immunoprophylaxis.
