Testing Changes Scheduled for BVD-PI Cattle


In an effort to provide more efficient results for Tennessee’s cattle producers and veterinarians, the Kord Animal Health Diagnostic Lab will change sample requirements for testing cattle persistently infected with bovine viral diarrhea (BVD-PI).

Beginning Oct. 14, the Kord Lab will require ear notch samples for BVD-PI testing. Serum samples for BVD-PI will no longer be accepted.


From now until Oct. 14, non-negative BVD-PI serum results will be reported as inconclusive and an ear notch will be required to confirm the diagnosis.

All other commonly requested herd testing will still be performed on serum samples.

For instructions on collection and submission of ear notch samples as well as materials and equipment needed, visit the Kord Lab guide at www.tn.gov/content/dam/tn/agriculture/documents/animalhealth/KAHDL.Lab.Guide.pdf.


If you have any questions about how to collect and submit samples, please contact the Tennessee Department of Agriculture’s immunology section at 615-837-5221 for further information.
