BVD Testing
Bovine Viral Diarrhea (BVD)
- Infection reduces reproductive performance by decreasing conception and inducing abortion
- Persistently infected (PI) calves developed in-utero lead to frequent death, poor performance, and ongoing reinfection within the herd
- Utilize ELISA (antigen) or PCR analyses and strategic pooling to reduce testing costs
Sample Types
- Milk
- Individual (fresh, frozen, or preserved)
- Bulk tank (fresh or preserved)
- Serum (fresh)
- Tissue (fresh or frozen ear notch)
WHEN TO USE
- Test tissue or blood samples from calves to identify PI animals
- Test individual or pooled milk samples from cows to efficiently clear adult herd of PI suspicion
Results
- Individual ELISA (milk, tissue, blood) available within 5 days of sample receipt
- PCR available within 10 days of sample receipt
- Reported as Positive, Negative or Suspect
- PCR samples that showed no evidence of BVD within the analytical range (maximum 40 Ct) are not reported with a specific Ct value, but rather are labeled undetected.

CentralStar’s laboratories provide sample analyses on milk, blood, fecal, and tissue samples for a variety of production, disease and health-related traits. More than 6 million samples are processed annually using state-of-the-art equipment and techniques including infrared spectroscopy, flow cytometry, ELISA, PCR, and more.
Diagnostic tests are intended to identify diseases for animal health, and do not determine the “safety” of milk.
