Abstract

Bovine viral diarrhea virus continues to have significant economic impact on the cattle industry worldwide. The virus is primarily maintained in the cattle population due to persistently infected (PI) animals. Herd surveillance, along with good vaccination programs and biosecurity practices, are the best way to mitigate losses and production of PI animals. Two PI calves were identified in a semi-closed beef herd with excellent management practices, highlighting the continued significance and persistence of this virus in the cattle population.
