Thoughts and recommendations on metaphylaxis in commercial feedyard settings with an emphasis on drug selection and postmetaphylaxis intervals
Year: 2025
Type: conference-paper
Abstract: Various antimicrobial drugs are approved for metaphylaxis in cattle at high risk for developing BRD. Although many can be used successfully, some antimicrobials appear to have superior comparative effectiveness across a broad range of BRD risk levels. Practitioners should familiarize themselves with the available literature to understand which antimicrobial(s) best meet the needs of their clients and the cattle they manage. Once a practitioner has selected an antimicrobial for metaphylaxis purposes, it is also recommended they familiarize themselves with the literature pertaining to post-metaphylaxis intervals (PMI). In general, extending PMI beyond what is traditionally regarded as prudent, results in reduced BRD treatments without deleterious effects on BRD mortality or growth performance. Additional considerations in selecting metaphylaxis agents and PMIs are discussed herein.
