IDEXX BVD-PI Testing

Bovine viral diarrhea virus (BVDV) causes a complex viral disease that supresses a cow's immune system, making it susceptible to a range of respiratory and reproductive illnesses. The virus can cross the placenta in infected pregnant cows causing reproductive losses due to abortions, stillborn calves and calves that die early in life. Calves can be born with the infection and remain infected for life, coninually spreading the disease to other animals. BVDV can affect cattle of all ages, in every herd size, worldwide and in every U.S. state. The infection is one of the most costly diseases for the cattle industry worldwide, with losses reported at $10-88 per head.

Signs of BVD

BVDV manifestations include:

• Clinical and subclinical infections
  
• Immunosuppression
  
• Repeat-breeding problems
  
• Abortion
  
• Congenital Defects
  
• Acute and chronic mucosal disease

BVDV makes cattle susceptible to other costly dieseases, such as:

• Bovine respiratory disease
  
• Pneumnia
  
• Scours
  
• Other viral and bacterial diseases
