The results of a seven year Johne’s disease control field trial in nine Wisconsin dairy herds is the subject of this 12 page special insert in the April 10, 2009 issue of Hoard’s Dairyman. This publication describes the overall results of the project and each of the nine participating herd owners gives their own perspective on the project and Johne’s disease control in general. This project is part of the larger USDA-funded U.S. National Demonstration Herd Project. Major funding agencies for this UW project were the Wisconsin Milk Marketing Board, the USDA-APHIS-VS, and the University of Wisconsin-Madison.
