The BVD Control and Eradication Project (BVDCEP) is a joint effort of WSU Extension, Vet Clinical Sciences, Animal Sciences and the Washington Animal Disease Diagnostic Lab (WADDL) funded through WSU Extension’s Issue-focused Teams Initiative. The goal of BVDCEP is to promote cow-calf herd health by

BVD is a viral disease that can affect cattle of all ages. It is in the same viral family as the viruses that cause hog cholera in swine and border disease in sheep. Scientists first identified BVD in a New York State dairy herd in 1946. This disease continues to have a heavy economic impact in the cattle

One of the most frustrating things that can happen to a cow/calf producer is to have a set of healthy growing calves start developing pneumonia during mid-summer while the calves are still nursing the cow. With some operations, this is an annual event, while with others it only happens sporadically.

What is it?
BVD is a viral disease of cattle that can cause many problems in a herd. Although the name would make you think diarrhea is the major problem, in most herds infertility is the most common and costly because it can go undiagnosed. Other problems caused by BVD include pneumonia, abortions

When the bovine fetus is exposed to the virus that causes BVD (bovine viral diarrhea) during the first 125 days of gestation, it can become persistently infected with the virus. During this early time of fetal life, the immune system is underdeveloped, and the calf essentially does not recognize this

There is no effective treatment that can alter the course of BVD infections, but most BVD virus infections are subclinical and self-limiting. If treatment is initiated, antibiotics, B vitamins, and fluids may be used in attempts to control secondary infections and provide supportive therapy. Changes

Subclinical BVD Infections
Approximately 95% of the animals that become infected with the BVD virus do not develop signs of disease that are directly caused by the virus, however, the BVD infection causes the animal's resistance to other infections to be reduced. This reduction in resistance quite

Getting the proper diagnosis and setting up a prevention plan is critical to stopping these continued losses, regardless of the enterprise that is on your operation. There are multiple options that differ in terms of the tests used and the associated costs, so it is important to understand which group

Herd signs will vary depending upon the type of animals you have (cow/calf vs. stocker vs. feedlot), the age at first infection (prior to or after the animal is born), and the level of immunity to the organism. Many times in older animals, BVD infections are uncomplicated and are not noticed because
