This episode is the third and final in a series of Have You Herd? podcasts discussing the publication in Zoonoses and Public Health published in November 2020. We are joined by lead author, Dr. Katie Hope, along with co-authors Dr. Mike Apley and Dr. Nora Schrag. In this episode, we discuss the findings of the beef feedyard study. Dr. Hope discusses the reporting results from the records systems they evaluated. We discuss how drug selection can affect use amounts due to milligram differences in products, as well as how regimen stacking can affect reporting. Dr. Apley reviews how lot size, placement weight and days on feed affects regimens/animal year and mg/kg of live weight sold, which is important to consider when comparing use data from different yards and lots. We also discuss the final paper in the publication which compared survey results with records data and explain the correlation between the two methods of reporting.
