BOVINE VIRAL DIARRHEA VIRUS SURVEILLANCE:

KNOW THE PREVALENT SUBTYPE IN YOUR AREA

A significant cause of sickness and death in the cattle industry, bovine viral diarrhea virus (BVDV) mutates and changes over time. Today, 78% of BVDV infections in the United States are caused by BVDV Type 1b.1 Knowing the prevalent subtype in your area will help you select the most appropriate vaccine.

TODAY, BVDV TYPE 1B POSES THE BIGGEST THREAT TO CATTLE IN THE United States2

While fewer than half of BVDV cases tested in 1988 were Type 1b, by 2008, it had become the predominant subtype, accounting for 61 percent of BVDV cases.2 Not all vaccines are specifically labeled — or proven — to protect against BVDV Type 1b.

What is BVDV?

Bovine viral diarrhea virus is extremely contagious, infecting cattle of all ages. Infection can lead to significant economic loss from decreases in reproductive performance, weight gain and milk production, as well as from death losses.

WHY ARE PERSISTENTLY INFECTED (PI) CALVES A CONCERN?

Acquiring the virus while in the uterus, PI calves are born with the disease and remain infected for their entire lives. PI calves often show no signs of disease, and can shed the virus at high levels every day, exposing the rest of your herd to infection.

HOW CAN BVDV INFECTION BE PREVENTED?

Work with your veterinarian to create a BVD prevention program tailored to the risks on your operation. Typically, you will need to:

Identify and eliminate PI calves

Vaccinate cattle with products that protect against the most common BVDV subtypes, including Type 1b

Establish a strict biosecurity program
