BVD Free Challenge 2019

Join the BVD Free Campaign 2019

Challenge 1: Have Your Say Survey

Tell us how you manage BVD.

Challenge 2: Build a BVD Plan

Use our tools to build a BVD plan.

Challenge 3: Test Calves at Weaning

Help us determine if screening tests can be used on calves at weaning.

Challenge 4: Review the Business Case

Test our BVD simulation model online.

Challenge 5: Share Your Lab Samples

Testing cattle for BVD virus?

Challenge 4: Review the Business Case


To obtain feedback from farmers and veterinarians on how well our computer simulation models capture and present the dynamics of BVD control across a range of different farm management systems and to allow farmers to explore the economic impacts of different potential national control strategies on their business.


Open 1st June 2019 to 30th June 2019


Completing this challenge will earn 15 entries into the prize draw.  Earn bonus entries by sharing a little more about the economic impacts of BVD in your herd or your practice to help us more accurately work out the total costs of BVD to industry.


  • Veterinarians must be registered to practice with the Veterinary Council of New Zealand (VCNZ)
  • Farmers must  own or manage cattle  herds that are registered in the National Animal Identification and Tracing (NAIT) system.  This includes commercial dairy herds, commercial beef herds, graziers, heifer rearers, and lifestyle block owners.


Visit the  home page and create an account if you have not already done so.

You will be asked to enter some basic details about your herd  demographics and management so that we can create a virtual representation of your herd in the computer simulation model.

After reviewing the model predictions, we’ll ask you to fill out a short survey (<10 minutes) telling us what you thought of the model interface and which national control strategy you would most likely support based on the predicted economic outcomes for your herd.                  

Why is this research important?

When we build computer simulation models to help evaluate the cost-effectiveness of different national control strategies, we often have to make simplifying assumptions about each herd. Having farmers tell us how well the model matches their farm situation and how well the interface communicates the results helps us improve these tools.
