SADA is now managing the SA JD Dairy Score program, which it inherited from PIRSA this year. This means that Certificates and risk ratings already applied in many cases for over 15 years will be maintained in cooperation with private Veterinary practitioners, as previously.

As you have previously indicated to PIRSA that you are happy for your details to be shared with SADA, we will be able to continue to support your participation in the program. SADA will issue certificates to producers who are enroled and will provide reminders for tests to Vets and producers as needed.

 

Please read the SADA JD Dairy Score Manual or alternatively give the office a call if you have any questions.

 

Bovine Johne's disease at PIRSA https://pir.sa.gov.au/biosecur...

The former Dairy ManaJD Program

The South Australian cattle industry, dairy processors and PIRSA developed the Dairy ManaJD program in 2004 based on a National Dairy Assurance Scoring system for Johne’s disease in Australian dairy herds.

This program was funded by the SA Cattle Industry Fund, administered through the SA Cattle Advisory Group that has representatives of both the beef and dairy industries. The program was designed in partnership with dairy food processors, SA dairy veterinary practitioners, the Dairy Authority of SA, and PIRSA.

The vision for Dairy ManaJD was to implement effective management of Johne’s disease in the South Australian dairy industry to improve on farm productivity, trade access and product quality through a quality management approach.

In South Australia, all Dairy Assurance Scores have been based on:

  • Full herd blood tests of individual cattle over 2 years of age, with follow-up of any reactors
  • Improved calf rearing (3 step plan) and calf credits, Annual audits
  • Biennial maintenance or Check Tests of the herd using the HEC (Herd Environmental Culture) test.
  • Individual Certificates issued to producers.

In 2018, most SA dairies were enrolled in the program, with over 70% of herds testing negative and maintaining this status. The SA program had significant differences to some interstate programs, but is now consistent with published scoring systems by Dairy Australia.

 

Objectives

  • Support producers affected with Johne’s disease to undertake management programs together with private veterinarians.
  • Provide information to South Australian Industry bodies on Bovine Johne’s Disease and its management and prevention in South Australia.
  • Provide training and accreditation for South Australian veterinarians who wish to assist producers in managing Bovine Johne’s Disease or maintaining high biosecurity standards.
  • Engage with SA cattle producers to improve the uptake of the One Biosecurity program and develop meaningful disease risk ratings for cattle herds (including J-BAS and J-DAS ratings).
  • Provide certification for herds wishing to have high assurance ratings.
  • Undertake reviews and updates of relevant PIRSA web sites as needed.

 
Methodology
  • Passive surveillance for BJD is undertaken by private practitioners with support from the Biosecurity Disease Surveillance Program and funding. Active surveillance is undertaken for cattle herds involved in J-BAS and J-DAS rating and monitoring programs under a producer paid arrangement.
  • Maintain confidential records of all reports in Objective and laboratory test results of Johne’s disease in cattle on the Primary Industries Information Management System (PIIMS) against the affected Property Identification Code.
  • Work with Livestock SA Biosecurity Officers and attend industry events to deliver JD information as requested and provide updates to private veterinarians (including attending SA rural veterinary conferences if possible) and undertake individual visits to rural vet practices as required.
  • The JD manager must maintain knowledge on JD and keep up-to-date with any new scientific research or national / international industry developments (particularly JD marketing issues including national and overseas export markets).
  • Manage the Johne’s Disease Market Assurance Programs (JD MAP’s), including J-BAS & J-DAS, to provide a level of integrity for South Australian cattle industry. This includes the provision of certificates for industry assurance programs, reminding vets and producers when testing is due/overdue, considering laboratory test results to maintain integrity of the system, plus the maintenance of operational manuals for the BJD assurance programs.
  • Provide disease management advice to affected producers and their consulting veterinarians. Assist veterinarians if they want to develop property disease management plans (PDMP’s) for producers where JD is detected.
  • Manage Silirum vaccine use in South Australia (requires CVO approval).
  • Provide training to veterinarians and final year students in JD Market Assurance Programs, and APAV ensuring a supply of trained vets is available to industry.
  • Provide six month and annual reports to the Cattle Industry Board and for reporting to the Minister.
  • Provide updates on activities to other producer, government groups and Animal Health Australia as required.
