Abstract

Four groups of heifers were each vaccinated twice with one of 4 commercially available inactivated vaccines containing IBRV and BVDV antigens: Vira Shield-4, Triangle 3; Premier IB and IBPL; Horizon II. Sera from all animals were antibody negative at first vaccination. Only Vira Shield-4 was effective in eliciting high serum neutralizing titres of cytopathic BVDV and IBRV antibodies that persisted over a 1-year period, and was the only vaccine to elicit more than a minimal level of antibody to noncytopathic BVDV.
