Bovine respiratory disease is the most common cause of death in feedlot cattle. Viral and bacterial pathogens have been identified as being primary or secondary causes of this deadly disease. Over the last 20 years, Mycoplasma bovis has been described as a pathogen of interest in acute and chronic BRD cases. Commercial and autogenous Mycoplasma bovis vaccines have been developed to immunize cattle from this pathogen. The objective of this study was to identify any differences in performance and animal health in lightweight, high health risk calves, vaccinated with a single dose of Mycoplasma vaccine [MYCO-B ONE DOSE (TM) AAH, Inc.] compared to similar calves that were not vaccinated.
