Introduction
The Michigan Johne’s Disease Control Demonstration Project
is a cooperative venture between Michigan
State University (MSU), Michigan
Department of Agriculture (MDA), and the United
States Department of Agriculture (USDA) to investigate and define
farm management factors that are effective in reducing Johne’s
Disease (JD) transmission and estimate the costs of those factors.
Seven dairy herds ranging in size from 80 to 520 cows milking throughout
Michigan are enrolled in the project. Herds represent a variety
of housing systems from total confinement, rotational grazing, to
a combination of each. A JD risk assessment was performed on each
herd upon enrollment in the project and a JD control program developed
for each individual herd based on the herd’s goals. The prevalence
of JD in the respective herds was determined by testing all adult
cattle using fecal culture and serum ELISA and is tracked annually
through repeated testing. Each herd’s risk assessment and
control program are also reviewed annually and updated as necessary.
