Herd-level prevalence of Johne's disease and BVD, management practices and farm characteristics for positive dairy herds in Utah and Idaho

Abstract

Johne's disease (JD) and bovine viral diarrhea (BVD) are expensive dairy cattle diseases causing production, infertility, and death losses. Herd-level prevalence estimates are 68% for JD and 15% for BVD. The objectives of this study were to estimate regional dairy herd-level prevalence of JD and BVD and evaluate farm characteristics, management, and control practices on farms with either disease detected.
