Abstract

Bovine Respiratory Disease (BRD) is a multifactorial syndrome associated with a number of bacterial and viral agents causing severe, and sometimes fatal, respiratory disease in cattle (Fernández et al., 2020). It is the leading cause of disease and death in feedlot populations with a global economic impact of over $3 billion/year (DeDonder and Apley, 2015), accounting for more than 80% of morbidity and mortality in feedlot operations in Australia (Blakebrough-Hall et al., 2020). Accurate and timely PCR-based diagnostics could reduce production losses and allow precision application of antimicrobial therapy by identifying individuals or cohorts at high risk of BRD.
