Milk ELISA Johne’s Testing Up and Running

 

The Sauk Centre and Zumbrota DHIA Laboratories are both up and running with the Milk ELISA Johne’s test, and USDA recently announced it has approved the test.  Over 1400 samples have been run so far at the two labs, and data is flowing to Minnesota DHIA’s data handling system for report generation and for reporting to the Board of Animal Health and University of Minnesota for research purposes relative to Johne’s prevalence.   Work continues to make selection of cows easier in the software, and to trap the data in the cowfiles for consultant and producer use.  Minnesota DHIA is grateful for the cooperation of the University of Minnesota Veterinary Diagnostic Lab, the Minnesota Board of Animal Health, Antel-Bio, and the College of Veterinary Medicine at the U of M.

 

RFID Tag Update

371 Herds have now ordered RFID tags from MN DHIA, totaling over 33,000 tags.  In a recent study on a member herd over a period of time, 10,080 cows walked past panel readers on their way into the milking parlor.  The stationary reader panel was able to identify 97.8% of the cows in routine operation.  Breaking the study down, 99.9% of cows with Half Duplex Tags were read, confirming our advice that if you plan to use RFID tags in the parlor, you should pay a little extra and get the Half Duplex Tags.  We thank Dr. Steve Stewart and the U of M College of Vet Medicine for their good work.

 

At least one major buyer of cull dairy cows reports paying an additional 3 cents per pound for source verified beef, has an RFID reader, and is using RFID on a limited basis as evidence of source verification.

 

Minnesota DHIA is selling both Digital Angel Full Duplex Tags and All Flex Half Duplex.  Both are USDA approved, both come with the USDA shield, both use the international 840 codes to satisfy current and future regulatory requirements, and both come only in white.  Digital Angel offers a combo tag that incorporates the RFID and a large visible management tag.  Ask your DHIA Field Rep for details.

 

Cow Page Corrections Complete / Available

Beginning in late January of last year, and continuing through the spring, our Dairy Records Processing Center, Agri-Tech Analytics (ATA) was implementing a new data processing system.  When they implemented one of the program changes, they mistakenly removed the application of AP factors for butterfat test on individual cows.  The net affect of this was that most cows sampled on a morning milking were not given enough butterfat credit, and most cows sampled on a night milking were credited with too much. 

 

When the problem was found, we requested that ATA correct all cows and Rolling Herd Averages.  They recently completed that project and Rolling Herd Average adjustments showed up in your reports starting this past fall.  ATA has now provided us with the corrected cow pages.  For those on the cow page option, corrected cow pages are available on request.  Please call us at 800.827.3442 or have your field rep include a memo on your next sample day.  Please note that the next routine cow page you get on a cow will have the corrections on them anyway.
