METHOD FOR PREVENTING GASTROINTESTINAL DISEASES IN CALVES Russian patent published in 2007 - IPC A61K39/112 A61K39/108 A61K39/39 

FIELD: veterinary science.

SUBSTANCE: down-calving cows should be immunized simultaneously with vaccine "Coli-Vac C99" and formulated alum vaccine against salmonellosis in calves at 10-d-long interval 1.5 mo before calving. The first dosage corresponds to 10 cu. cm, the second one - 15 cu. cm. Simultaneously with vaccination it is necessary to inject Ligavirin for cows at the dosage of 5 ml/cow. As for calves born in these cows they should be once injected intramuscularly with Ligavirin for 0.5-1 h after their birth at the dosage of 1 ml/calf. The innovation enables to create more tense specific immunity in cows before calving and colostral immunity in calves born in these cows.

EFFECT: higher efficiency of prophylaxis.
