AbstractBovine Johnes disease (BJD) impacts dairy industries globally. Australia and Canada have low cow-level prevalence with varying herd-level prevalence and recently reviewed control activities. Control strategies using vaccination are lacking, suggesting opportunities for improved efficiencies of regulatory oversight. Aims of this study include identifying characteristics of producers participating in BJD control programs and vaccination, financial benefits of participation, and comparison of control activities in Australia and Canada to inform current and future control policy. An online questionnaire captured knowledge, attitudes, and practices plus demographics from 71 Australian dairy farms. Ordinal choice variable analysis identified several influences on participation, including economic factors. Simulation modelling suggests increased profitability through participation in BJD control programs and vaccination. Financial benefits of BJD control in different countries indicates high likelihood of positive returns for long-term programs, but short-term challenges to adoption and sustainability. Canada’s BJD regulatory policies may benefit from Australian experience with BJD control.
