                               Demonstrating JD assurance pays off
                               The past few years have seen major changes in the way we manage Johne’s
                               disease in all species in Australia. Ten years ago we started to move more towards
                               focusing on assurance of herd and flock status with the start of the JD Market
                               Assurance Programs. There are now four MAPs; for cattle, sheep, goats and
                               alpaca. They are voluntary programs based on risk assessment and biosecurity
                               management, demonstrating status by herd and flock testing and demonstrating
                               compliance by record keeping, annual reviews and regular external auditing.

                               The MAPs are now complemented by other QA schemes including the Assurance Based
                               Credit (ABC) Scheme for sheep, Beef Only and Q-Alpaca that are more attractive to
                               commercial producers. The dairy industry has also just finalised the National Dairy BJD

          All of these QA schemes depend very heavily on the people making the declarations both
          understanding how to do it correctly and then declaring the correct score. It would be nice
          to be able to have confidence in everyone all the time but, of course, the world doesn’t
          work like that. If producers and others are to continue to have confidence in QA schemes,
          they have to be based on more than just another producer’s declaration. The schemes
          themselves have to be monitored to demonstrate that they are “producing the goods.”

          This edition of JD News includes updates on using the new Dairy Assurance Score in South
          Australia and auditing sales of Beef Only cattle in Victoria. The dairy Assurance Score for
          herds in the voluntary SA Dairy ManaJD program is based on auditing to check that the
          farm conforms with the program.

          The Victorian Beef Only sale audits in 2005 found very high levels of compliance, as they did
          in 2004. This type of information has given Queensland confidence to change its movement
          requirements and allow entry of cattle to that State from Beef Only herds from June 2006,
          without the need to test the herd.
          In the past decade, the livestock industries in Australia have reviewed and renewed their
          decisions to manage JD in this country. The approaches have moved very much from
          regulated programs largely run by governments to more sustainable assurance programs
          that are based on risk assessment and management and backed by the livestock industries.
          It’s critical to their ongoing success that they are sound and this success is regularly
          demonstrated by audit and by monitoring the JD situation in assured populations.
          David Kennedy, National Johne’s Disease Technical Advisor.

          Johne’s Disease in SA - what’s the score?
          Nearly two thirds of all South Australia’s dairy farmers have now enrolled in the SA
          Dairy ManaJD program to test their cattle for Bovine Johne’s Disease.

          This is great news and shows that farmers are recognising that knowledge about BJD is
          important as a management tool. Those who have disease-free farms can now ensure that
          they do not introduce it, and those with BJD on their farms can manage it on a test-and-
          control program, and gradually improve their Dairy Assurance Score.
          Most SA dairy farms are not infected with BJD and there are now over 150 Score 7-10
          dairy herds in the State. Herds that are infected tend to have low levels of the disease and
          only three herds so far have more than 2% of cow reactors at the first test. So far, only 20
          new herds have been detected in the testing program, and most infected cattle do not
          appear as clinical animals, indicating that farmers are living with BJD without recognising
          this. There are two points to be aware of:
          1. Subclinical disease costs farmers money (up to $50 per cow in the herd per year see
             below )
          2. The previous categories of “No known Johne’s“ or “Non Assessed” have very low levels
              of assurance.

          Declaration of scores
          Declaration of the Dairy Assurance Score is required for all sales of dairy cattle in SA,
          including private sales and trade of cross-bred cattle born on dairy farms. This declaration is
          a simple matter of marking the National Vendor Declaration in section 9, or using the special
          declaration forms found in the Dairy ManaJD manuals. In SA, cattle that are being sold with
          a dairy score of 7 or above are achieving improved prices and there are constant enquiries
          from farmers wishing to source score 7 or higher dairy cows or cross bred cattle. Buyers
          and agents are increasingly looking for information on herd BJD status in order to assist in
          purchasing decisions.

          Costs of BJD
          A common misunderstanding by farmers is that BJD is not a real cost in milking herds due
          to the low levels of disease. Recent studies however indicate that this may not be the case.
          A study presented at the recent Colloquium on Johne’s Disease in Copenhagen examined
          a dairy herd in Ireland and the consequences of the introduction of the disease.Prior to the
          introduction of infected cows (from Belgium) in 1998, the herd was in the top 10% of herds
          in the district.      >>

Beef Only - trading with confidence in South Eastern Australia
As a result of experiences with testing beef herds and following extensive trials of Beef Only sales, the beef
cattle industry and Animal Health Committee agreed in July 2004 that cattle from herds that qualify as Beef Only
represent a very low risk for bovine Johne’s disease.

They also agreed that breeding cattle originating from herds that qualify as Beef Only could be traded into the bovine Johne’s
disease Protected Zones in New South Wales, South Australia and Tasmania without the herd of origin having to be tested.
The specific eligibility requirements of the Beef Only scheme have now been recognized nationally for over 12 months and
many cattle have been traded under the scheme.
Auditing of the Beef Only scheme is conducted on a regular basis by state animal health authorities. Routine audits of
randomly selected lots are conducted whenever Beef Only cattle are presented in a sale yard. Intensive audits, where
all lots are closely scrutinised and a minimum of 5% of vendors are selected for a detailed on -farm audit, are also
conducted. Figures recently released by the Victorian DPI (Tables 1 and 2), show a high level of compliance with the scheme
This means that buyers can be confident about the statements made on National Beef Only Animal Health Statements and in
the high bovine Johne’s disease assurance of Beef Only cattle.
