BVD is Affecting Your Operation so you should be BVD-PI Testing
Bovine viral diarrhea virus (BVDV) suppresses a cow’s immune system, making the animal susceptible to a host of other infections. That’s why BVDV is one of the world’s most costly bovine diseases, with losses of up to $30 per head for dairy and beef producers alike.
Stopping BVDV requires detecting and removing the infection source: persistently infected (PI) cattle that continually expose other animals to disease.
Because PI cattle often look healthy, a sensitive, specific diagnostic test is essential. Mistakes can be costly: whether it’s removing a valuable animal from production or allowing an infected calf to join the herd.
BVD challenges producer profitability with increased abortions, stillbirths and risk to healthy cattle. It challenges stocker operations and feedlots with reduced gain and increased sickness and death. Experts estimate that the financial impact of BVDV averages a loss of $30-$40 per head. BVD testing can save cattle and money.

Some PI calves are easy to spot. They’re smaller than their herd mates and struggle with health problems. However, other PI calves may not show symptoms, and you may not be able to tell them apart from healthy calves.
