Bovine Virus Diarrhea (BVD) is a devastating disease of all cattle. The disease reduces productivity and increases death loss of cattle. Clinical signs of mucosal erosions and diarrhea have obvious impacts on infected animals, but more devastating are those animals that do not live up to their potential through lower weight gains, increased disease susceptibility, and diminished reproductive performance. Vaccinations are an integral part of any control or eradication program, but alone will not control the disease. Controlling BVD is no small task, but several organizations with vested cattle interests such as the Academy of Veterinary Consultants and American Association of Bovine Practitioners have proposed programs to address BVD control. Key to the success of these programs is testing, vaccinations and biosecurity.

The major source of BVD infection is persistently infected animals (PI's). PI's result from cows being exposed to the virus during pregnancy and the fetal calf becoming infected. Although frequently these calves show no signs of illness themselves, they shed the virus in such great numbers that even well-vaccinated animals may become infected. The Colorado Voluntary BVD program is a multilevel program that will address the components necessary to bring this disease under control.
