Newly-arrived cattle first go through an analysis upon arrival, which includes processing and a look at their health status. Because incoming cattle often come from multiple sources and are comingled, standard protocol is to run the cattle through the processing chute on arrival, where they are worked to ensure they get off to a good start. This initial processing can include, among other things, vaccinating, implanting (if not part of a natural or NHTC program) and tagging each calf. If the cattle are from a single source and the feedyard manager is familiar with their management on the ranch, this initial step may be skipped.
