Abstract

We set out to evaluate differences between vaccinated and non-vaccinated calves reared under the same conditions. Three larger Wisconsin dairy herds (300-800 head/herd) agreed to participate in the study. Every other heifer calf was vaccinated
against JD until two cohorts, vaccinated and non-vaccinated, were established for each herd. Infection prevalence, clinical disease rate and longevity in the herd will be evaluated in the study.
