Johne's Disease Control Program
Johne's disease (pronounced YO-neez), or paratuberculosis, is a chronic intestinal infection in cattle and other ruminants. Herds may be infected at low levels, cutting into production, long before symptoms are apparent.

In Wisconsin's dairy cattle industry alone, the disease is costing an estimated $54 million annually in reduced milk production and decreased weight. Dairy farmers with infected herds may be losing as much as $235 a year for every animal in their herds.

Cattle
How the disease shows itself, spreads and affects both dairy and beef cattle herds.

Other Species
Farmers who raise goats, sheep, or exotic species, such as deer, elk, or bison need to watch for Johne's disease in their herds.

Herd Classification Program
A voluntary program to help producers cut costs and increase profits, and reimbursement is available to help cover testing costs for farmers who participate in the program.
