Abstract

Risk assessment (RA) based Johne's disease (JD) control programs are used in many countries. A RA is an on-farm questionnaire that probes management practices in the calving area for different age groups of heifers and cows. The higher the assigned score, the higher the risk of spreading JD on farm. Based on the score, veterinarians make recommendations for management changes to reduce the risk of JD spread on that farm. The success of RA based programs is not only dependent on the correct identification of high risk areas but also the compliance of producers with suggested management changes. The objectives of this study were to evaluate a voluntary JD RA control program in Ontario and western Canada and to assess the producers' perceptions of the program.
