BVD in calves costs more than you think

Calves born persistently infected with BVDV are often weak and 10 to 15 pounds lighter than non-infected calves born in the same herd.

Calves born persistently infected with bovine viral diarrhea virus often look normal, but they are immunologically frail. In fact, 50 percent of PI calves will die within the first year of life, says Victor Cortese, veterinarian with Pfizer Animal Health. Another 40 percent will die before two years of age. That leaves just 10 percent that will make it to two years of age.

These animals are the first to die in any disease outbreak and are the primary source for spreading BVD on the farm. Those are two good reasons why you should test and remove PI calves and their dams.

Your veterinarian learned about BVDV in the February issue of our sister publication, Bovine Veterinarian. Ask him about it.
