Johne’s Test Now Available on DHIA Milk Samples

For the past several months, the University of Minnesota Veterinary Diagnostic Laboratory and the DHIA Labs in Sauk Centre and Zumbrota have been gearing up to offer the Milk ELISA Johne’s tests to Minnesota dairy producers.  The test is now available.  It utilizes the same DHIA milk sample collected for butterfat, protein, and SCC.  Extensive research and testing show the milk test to be very comparable to the serum ELISA Johne’s test that has been a standard test for many years.  ELISA tests are looking for the antibodies the cow creates to fight a specific disease, not the disease itself.  Once sampled, the antibodies do not grow, research shows the small amount of milk that is left in a flask from one cow to another does not impact the result for a cow.

 

The obvious advantages of the milk test include that sampling is easy (and inexpensive) compared to taking blood samples, results will be fast, and that the data will be integrated into the DHIA database and reporting system for your herd.  We will provide the numerical result and positive or negative status.  Please see the following joint release for more information.  To order the test on selected cows or the whole herd, simply talk to your DHIA Field Rep on your next sample day.

 

USDA funding for Johne’s sample collection (serum or feces)  is no longer available according to the Board of Animal Health, so producers will now need to pay for collection of those samples.

 

We urge producers to work with your Veterinarian on using Johne’s test results, and contact the Minnesota Board of Animal Health for more information about their Johne’s control assessment tools and programs. 

 

In compliance with the regulation that Johne’s is a reportable disease, we will also report results to the Board of Animal Health.  The Board of Animal Health and University of Minnesota will use the results for statistical and research purposes only.  Results will not appear anywhere in the public record, and no follow up on herds will be pursued as a result of the Milk ELISA Johne’s test.  We will submit the data under your herd’s Premises ID that you have probably received from the Board of Animal Health as a part of the developing National Animal Identification System that is designed to track animal diseases in the event of an Animal Health Emergency.  Register your Premises today by calling the Board of Animal Health at 651.201.6816 or go to www.bah.state.mn.us.  You will need your Premises ID number to participate in the Milk ELISA Johne’s Test.

 

Producers who have vaccinated against Johne’s should not use the ELISA tests.
