This document discusses considerations for veterinarians in issuing veterinary feed directives (VFDs) in practice. It outlines scenarios like needing a VFD for a medication in feed for 3 weeks and issuing an internal VFD. It also discusses what is required like providing copies of the VFD order to distributors and clients and retaining records. Potential challenges are addressed such as issuing VFDs for herds with different structures, impacts on time, communication needs, and how VFDs may change the role of swine veterinarians.
