Veterinary Feed Directive
The Veterinary Feed Directive rule was finalized by the FDA in 2015 after passing through the Federal legislative process; it goes into effect January 1, 2017. Under the new rule, certain over-the-counter drugs will be available by prescription only, while other drugs are available through a Veterinary Feed Directive (VFD). Not all antibiotics are included, only "medically important" antibiotics as deemed by FDA.
A Veterinary Feed Directive (VFD) is a written order from a licensed veterinarian to a client in order to purchase and use certain medications in or on animal feed. A Veterinary Feed Directive (VFD) listed drug is different from a prescription drug because the VFD is for use in feed only, and is not for injection or water use. The VFD listed drugs cannot be used for anything but treatment - not for growth promotion, etc. The VFD applies to everyone handling medicated feed, such as producers, veterinarians, and feed mills, and requires record keeping by all parties (producer, veterinarian, feed mill).
Examples of drugs that will require a VFD: Tylan, Lincomix, Hygromix
