HISTORY
JOHNE'S INFORMATION CENTER - University of Wisconsin Ñ School of Veterinary Medicine



Bar
Thursday, March 1, 2001
Wisconsin Johne's herd status update July 1, 2000 Wisconsin started a bold plan to classify all cattle herds in the sate based on laboratory test data. In spite of low milk prices that have dampened herd owner's desire to spend money on herd testing, many herds have already been tested and most were found to be test-negative for Johne's disease. The number of herds in each herd classification are shown on the attached graph. Specific rules regarding the herd classification system can be found in a handout available on this site.
