BVD Eradication Story

Bob eradicated BVD, and saw his calf mortality drop from 12-14% to 0% in the first year, and 1% the year after.

Bob said:

“We weren’t aware of BVD, until someone explained how a PI was created. After blood testing the whole herd, seven PIs were found and removed. Only one of the PIs was way behind growth. The other six PIs looked fine. Three of them were my best calves in the bunch”.

Dairy

Bob stressed the importance of testing, as you cannot tell which animals are PIs.

“It’s worth the time invested, to see virtually no calf mortality and better resistance to other diseases. We now use 75% less antibiotics for calves.”

To ensure BVD stays out, Bob does annual; blood tests for female young stock, a bulk milk test, and vaccinates everything. This regime has kept BVD out since eradication two years ago.

Bob advises “make sure you stick to your BVD vaccination programme”.
