About Bovine Viral Diarrhoea Virus (BVDV)
​
Bovine viral diarrhoea virus (BVDV) suppresses a cow's immune system, making the animal susceptible to a host of other infections. That's why BVDV is one of the world's most costly bovine diseases, with losses of $15–$88 per head from reduced herd productivity, health and reproductive efficiency.
Stopping BVDV requires detecting and removing the infection source: persistently infected (PI) cattle that continually expose other animals to disease.
​
Because PI cattle often look healthy, a sensitive, specific diagnostic test is essential. Mistakes can be costly: whether it's removing a valuable animal from production or allowing an infected calf to join the herd.
Determining herd status is the first step toward a BVDV-free herd.
Want to test for BVDV on-farm? Use this cow side PI test!
​
Persistently Infected (PI) cows are lifelong carriers of the BVDV virus and shed hundreds of thousands of virus particles. Enough to overwhelm the immune system of animals they come into contact with (and even enough to overwhelm some vaccinated animals). PI’s propagate the BVDV virus and identification and management of PI’s is crucial to controlling BVDV. You cannot develop a persistent infection. Cows are born as PI’s and then are PI’s for life. ​
The IDEXX Bovine Viral Diarrhoea Virus Antigen Point-of-Care Test detects bovine viral diarrhoea virus (BVDV) in cattle, using ear-notch (or ear-tissue biopsy) samples.
The IDEXX BVDV Ag Point-of-Care Test can be used to test ear notch samples to identify persistently infected animals. It produces results about an animal’s BVD infection status within 30 minutes

Strategic times producers should use this test
Not sure when to use this test? Here are some key times you should be using this test:
Testing / Checking Introductions​
Bulls
Newborns
New Animals Brought In
Importance of Biosecurity
Producers should be using the BVDV POC test as a necessary biosecurity screening tool to ensure no PIs are introduced to the farm. Just one PI can cause significant costs to a producer.
Any bulls, heifers, cows and/or calves should be tested prior to being introduced to the herd
Regularly Testing Suspect Animals
Importance of Spot Testing
Persistently infected animals are not always easy to find. PIs often dont perform as well and look sick, but they can also hide in plain sight as healthy animals.
Spot testing suspect animals is an important management procedure that can help producers identify PIs in their herd.
