Abstract: Operations in a livestock facility can be automated and made more efficient by utilizing an interrogator system that reads and writes data to tags associated with livestock. For instance, gates can be automated to sort livestock based on data read by interrogators from tags and livestock can be identified for examination when data suggest that their behavior deviates from expected or normal behavior. The tag associated with a livestock can carry and accumulate information across multiple facilities throughout the livestock production and processing cycle. Gathering information across facilities allows for more informed decision making and a more cooperative approach to improving the livestock production and processing cycle.
