For cattle with bovine viral diarrhea virus (BVDV), diarrhea isn’t the main problem. Less obvious signs can presage economically significant reproductive and respiratory problems. What’s more, persistently infected (PI) calves shed the virus, placing the rest of the herd at risk. In this podcast, Successful Farming editor Bill Spiegel interviews Dr. Chris Chase, a veterinary immunologist at South Dakota State University, about proactive strategies for managing BVDV.

In a three-pronged approach to BVDV management, Dr. Chis Chase shares why bulk-milk testing can be an effective screening tool In large dairy herds, but not for smaller operations.
In terms of biosecurity, Dr. Chase shares his recommendations for how to safely merge replacement heifers into your existing herd.
You’ll also learn about BVDV vaccination timing — when is the best time for modified-live-virus vaccines and when should inactivated vaccines be used. Dr. Chase also shares new findings on the emergence of BVDV type 1b, and why your vaccine should include protection against this subtype. He’ll also discuss the role of the Singer strain of type 1a in vaccines and how it can provide additional protection against BVDV 1b.
Your veterinarian can play a key role in developing an effective BVDV vaccination strategy, including how to help pregnant animals develop plenty of antibodies for the colostrum, to help new calves off to a strong start.
