Abstract
The effects of a maternal vaccine against newborn calf diarrhea associ ated with group A bovine rotavirus (BRV), bovine coronavirus (BCV), bo vine parvovirus and K99 Escherichia coli (E.coli) were examined on a b eef cow-calf herd. After vaccination, serum or colostrum antibody tite rs to BRV, BCV and E. coil K99 in the vaccinated cows were significant ly higher than those in unvaccinated control cows. Serum antibody tite rs to BRV, BCV and E. coli K99 in calves from the vaccinated cows were also significantly higher than those in calves from the control cows for 3-4 weeks after birth. These results suggested that the immunizati on of cows with the maternal vaccine enhanced the passive immunity lev els in calves against BRV, BCV and K99 E. coli.
