EmailThe Michigan Johne’s Disease Control Demonstration Project is a cooperative program between the Michigan State University (MSU) College of Veterinary Medicine (CVM), Michigan State University Extension (MSUE), Michigan Department of Agriculture (MDA), and the United States Department of Agriculture (USDA).
This project was part of the larger National Johne’s Disease Control Demonstration Project. The objective of the project was to demonstrate and investigate management factors that are effective in controlling Johne’s Disease (JD).
The project goals were as follows:
• To evaluate the effectiveness of JD control strategies.
• Develop new knowledge on JD control through field research.
• Promote the Michigan Voluntary Johne’s Disease Control Program.
• Develop JD education resources.
Eight Michigan dairy farms and one beef operation were enrolled in the project . The enrolled herds represented a variety of management systems. Initially, a herd risk assessment was conducted to identify areas on the operation where JD might be transmitted. Subsequently, a JD control program was developed for each individual herd. This plan was developed in cooperation with the herd owner/management, their herd veterinarian, and other appropriate personnel such as MSU Extension Livestock Educators, nutritionists, USDA veterinarians, and veterinarians from MSU. The prevalence of JD in the respective herds was tracked annually through repeated testing. Each herd’s control program was reviewed annually and updated as necessary. Farms participated in the program for 4 to 7 years. Information gathered from this long term interaction was then incorporated into research and educational efforts.
