Bovine Viral Diarrhea (BVD) is a disease of cattle caused by the Bovine Viral Diarrhea Virus (BVDV). The virus is widespread, and most herds are at risk for infection. In the susceptible herd, BVD can be a serious, costly disease. The signs of BVD vary, depending on the immune status of the exposed animals, and the strain of the infecting virus.

Bovine viral diarrhea (BVD) is a contagious viral disease of cattle and other ruminants. The disease was first seen in 1946 in New York as a gastro-enteritis with severe diarrhea, ulcerations of the muzzle and nasal and oral cavities, fever, leukopenia, reduction in milk production, cessation in rumination, and abortions.

Bovine viral diarrhea (BVD), bovine viral diarrhoea (UK English) or mucosal disease, previously referred to as bovine virus diarrhea (BVD), is an economically significant disease of cattle that is found in the majority of countries throughout the world. [1]

A BVD positive bulk tank indicates: Acutely infected cattle with circulating BVD OR; One or more persistently infected cattle OR; Both acute infection and PI animals The bulk tank sample is centrifuged, and a pellet of somatic cells is collected and used for testing.

Cattle infected with bovine viral diarrhea (BVD) virus can show several different clinical signs, though the most important effects of BVD infection in a cow-calf herd are associated with reproduction. BVD can cause decreased fertility, abortions, and …

BVD is spread mainly by calves that were infected during early pregnancy and not aborted. These animals are referred to as persistently infected or PI calves. The resulting problems are mainly reproductive loss in cows though cattle may have a number of other symptoms. The cost of BVD has been estimated at $10 to $14 per cow in the breeding herd.

BVD or Bovine Virus Diarrhea is an infection that can cause numerous problems in cattle, including damage to the digestive and immune systems and birth defects. BVD can cause high mortality in calves and yearling cattle. The outbreak of this disease has devastating economic consequences to cattle producers.

Bovine Virus Diarrhoea Virus (BVDV) is a viral disease of cattle that causes reproductive losses and a range of other disease syndromes in cattle. The costs of reproductive failure and production losses can be very high and many countries have introduced eradication schemes for the virus with varying success.

Bovine viral diarrhoea (BVD) is a highly contagious viral disease of cattle. It is one of the biggest current disease issues facing the UK cattle industry. What are the clinical signs of the disease? BVD virus affects cattle of all ages, but clinical signs of infection are most common in young cattle (aged 6–24 months). Clinical signs include:

Bovine viral diarrhoea (BVD) is a costly infectious disease for the dairy and beef industries. Advances in the knowledge of disease transmission, diagnostic tools and the introduction of effective vaccines have enabled the control and eradication of the BVD virus from infected herds.
