BVDV

Not sure how to control BVDV? Follow this testing framework!

BVDV is an insidious and complex disease that presents specific management challenges to producers and veterinarians. In Australia management of BVDV is voluntary and so any framework provided must reduce as many barriers to uptake as possible.


Our aim is to provide a BVDV surveillance and testing protocol for vets to implement and work through with farmers which will facilitate the control of BVDV on Australian dairy farms whilst offering the most efficient and economical solution for farmers.

Biosecurity

If you are satisfied there are no PI’s in the herd it is important to implement biosecurity measures.

New animals brought in

Use IDEXX Antigen ELISA on ear notch samples to identify persistently infected animals. This can be conducted in situ using the IDEXX BVDV Ag Point-of-Care Test. Speak to your vet about using this test.

Trojans
In calf heifers brought onto the farm, or grazed off farm can become infected whilst pregnant. Whilst these animals will not test positive as a PI themselves, they can give birth to PI calves. This is why it is essential all calves are tested.

Vaccination
If there is a reasonable risk of exposure vaccinate mating cows and bulls to ensure maximum protection during mating and pregnancy. Bulk milk testing should be conducted at least one month after vaccination.
