In a previous study we determined the effects of testing and removing cattle persistently infected (PI) with bovine viral diarrhea virus (BVDV) at revaccination. We found that there were no statistical differences for mortality, retreatment, performance or carcass characteristics. However, we did find morbidity to be statistically different between the two cohorts (19 % for non- PI exposure vs 30 % for PI exposure). In light of our previous findings, a new research trial was completed to determine the effect of testing and removing PI-BVDV cattle on arrival to the feedlot and the outcome on health, performance and carcass characteristics.
