Ear-notch calves for BVD

One of the poor-doers was indeed positive for BVD. Then, the farm tested all 200 of the calves in the barn, finding eight more positives. It came as a surprise, because the eight calves all appeared healthy. Eventually, the positive animals were culled.

Swift relates this story to her clients so they, too, will see the need to check for BVD, using the BVD skin test. 

If BVD shows up in the skin cells of an animal, there is a high likelihood — greater than 95 percent — that the animal is persistently infected and capable of spreading the disease to others, says Dan Grooms, veterinarian at Michigan State University.
