The effects of a maternal vaccine against newborn calf diarrhea associated with group A bovine rotavirus (BRV), bovine coronavirus (BCV), bovine parvovirus and K99 Escherichia coli (E. coli) were examined on a beef cow-calf herd. After vaccination, serum or colostrum antibody titers to BRV, BCV and E. coli K99 in the vaccinated cows were significantly higher than those in unvaccinated control cows. Serum antibody titers 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 immunization of cows with the maternal vaccine enhanced the passive immunity levels in calves against BRV, BCV and K99 E. coli.
在一个肉牛犊牛群中，研究了一种用于预防新生牛犊腹泻的母源疫苗的效果，该腹泻与A组牛轮状病毒（BRV）、牛冠状病毒（BCV）、牛细小病毒和K99大肠杆菌（E. coli）有关。接种疫苗后，接种母牛体内针对BRV、BCV和E. coli K99的血清或初乳抗体滴度显著高于未接种疫苗的对照母牛。接种母牛所产犊牛在出生后3至4周内，针对BRV、BCV和E. coli K99的血清抗体滴度也显著高于对照母牛所产犊牛。这些结果表明，用母源疫苗对母牛进行免疫可提高犊牛对BRV、BCV和K99大肠杆菌的被动免疫水平。
