Testing Changes for BVD Persistently Infected Cattle Takes Effect

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

Kord Lab requires ear notch samples for BVD-PI testing. Serum samples for BVD-PI herd screening will no longer be accepted.

To detect transient/acute infection in clinically symptomatic animals, serum samples may be used.  Please indicate that this is the case on the submission form.  Otherwise it will be assumed that the test is being requested for herd screening and an ear notch will be required. Please contact the lab at 615-837-5221 for guidance on appropriate sample collection and submission.

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 here.
