Johne's disease in sheep and goats appears to be common in Ontario dairy sheep and dairy goat herds. The bacterial infection is difficult to diagnose prior to clinical signs appearing. Vaccination will reduce losses due to the disease and will also reduce fecal shedding. Test and cull is expensive, and will take years to reduce the prevalence of disease. It is important to combine any control program with sanitary measures that reduce the transmission of the bacteria to replacement animals and other uninfected animals in the flock.
