Bovine Johne’s Disease
Bovine Johne’s Disease management in QLD is changing and will affect every beef herd.
At the moment, we’re in a transition period while changing to the new national JD management system. The transition arrangements end 30 June 2017.
On-farm biosecurity plans and vets are involved with the new management of BJD.
· All properties with no prior infection have been given a score of 7 in the Beef Assurance Score scheme [J-BAS] – which is a “low risk status.”
From 1 July 2017, beef owners can either maintain that score; drop to a lower score; or increase to J-BAS score 8: maximal assurance, according to the what is put in place.
If you do nothing and do not apply an on-farm biosecurity plan by June 30, 2017, beef herds will drop to a J-BAS score of 0.
Please go to the DAF website’s page “Johne’s disease management in QLD” for more information by clicking on the following link:
- To maintain J-BAS score 7 you need to:
- By June 30, 2017 apply an on-farm biosecurity plan developed, implemented and reviewed annually by vet
- By June 2018 check test 50 head [dung samples most accurate – too many false positives in Northern Australia with a blood test. Faecal PCR, as opposed to faecal cultures, is the speedier process.]
- Ongoing: annual review of biosecurity plan by vet + check test 50 head every 3 years.
Biosecurity plans are to do with the “whole” of biosecurity: weeds, pests and diseases – BJD is only one part of it.
