The Nebraska State Fair announced it will require cattle entering the fairgrounds to be tested for BVD-PI this year in an effort to prevent its spread. Though the state does not require all cattle to be tested for bovine virus diarrhea, the state veterinarian supports the move. "BVD-PI is potentially a high-impact disease that can cause abortions in bred animals if a susceptible animal comes in contact with a positive animal," said state veterinarian Dr. Dennis Hughes.
