Abstract

Despite preventing morbidity and mortality in properly immunized cattle, sometimes bovine viral diarrhea virus (BVDV) vaccines have failed to prevent reproductive consequences of BVDV infection, in particular, persistently infected animals.

High (SN) titers may provide fetal protection in at-risk breeding heifers. Our objective was to test different types and sequences of administration of killed and modified-live virus (MLV) vaccines to determine which produced the greatest titer response.
