 Resize text         Printer-friendly version of this article Printer-friendly version of this article

Surveillance data indicates that more than 70 percent of U.S. dairy cows have been exposed to the bovine viral diarrhea virus. Thus, its presence is real and a threat to the long-term success of dairy herds.

Left unchecked, BVD can be the cause of poor reproductive efficiency, abortions, loss of milk production, impaired growth and unthrifty young stock.

The Dairy Cattle Reproduction Council (DCRC) advises a comprehensive BVD control program that includes:

Diagnostic testing for BVDV to confirm clinical cases and identify persistently infected (PI) animals.


Biosecurity measures.

DCRC cautions that pursuing one vein of this control program without the others will result in substandard control.
