“The most significant change in the updated Voluntary Bovine Johne’s Disease Control Program is the new six-level testing classification system,” adds Dr. Elisabeth Patton, chairman of U.S. Animal Health Association’s Johne’s Disease Committee.

“Producers who participate in the testing component of the Program will find a new six-level classification system that has specific criteria for different sizes of herds: 1-99 head, 100-199 head, 200-299 head and more than 300 head. A significant amount of thought and work went into the development of this new six-level classification system to address concerns with the previous system and to improve the accuracy of herd classification.”
