Bovine Viral Diarrhea (BVD) is a disease that suppresses the immune system and exacerbates other existing problems in the herd, thus greatly impacting various segments of the beef industry. In this episode, Dr. Bob Larson provides a lot of valuable information on the use of diagnostic tests to detect BVD in persistently infected (PI) calves, since they are the major contributors to the spread of the disease. He also discusses vaccines and their limitations, as well as a holistic strategy to successfully control BVD in our herds.

“Most of our prevention and all of our testing efforts are really focused on these persistently infected animals.” - Bob Larson
