Efficacy of statistical process control procedures to monitor deviations in physical behavior for preclinical detection of bovine respiratory disease in feedlot cattle

•Previous analyses have shown reductions in activity prior to BRD diagnosis.•This experiment was an SPC analysis of cattle activity traits for BRD detection.•SPC analysis of cattle activity traits yielded low accuracy in disease detection.•Activity traits likely have high daily variation which inhibits disease detection.•Future research should incorporate feeding behavior into detection models.
