Abstract

The objective of this field trial was to determine the efficacy of a commercially produced Mycoplasma bovis (Mb) bacterin for the prevention of Mb-associated disease (respiratory disease, otitis media, arthritis) and mortality in dairy calves from birth to 90. days of age. Additional objectives were to compare vaccinated and placebo-treated calves with respect to 1) weight gain from birth to 90 days of age, 2) rates of nasal colonization by Mb and 3) Mb-specific serum immunoglobulin concentrations.
