Risk Assessment tools for dairy herds – 2011 versions.
Instructions and forms created by the U.S. National Johne’s Working Group.

These two documents are the official risk assessment tools used in the U.S. to assist beef cattle producers identify and rectify management practices that allow transmission of Johne’s disease in cattle herds. These forms can be used unofficially by producers to gauge their herd management as it relates to Johne’s disease prevention and control. These same forms are used by Johne’s Certified Veterinarians to perform official herd risk assessments and generate herd plans. These forms are filed with the appropriate state Designated Johne’s Coordinator (DJC). If approved by the DJC, the herd is considered enrolled in the U.S. national Johne’s program.
