As defined by the FDA, a "combination VFD drug" is an approved combination of new animal drugs intended for use in or on animal feed under the professional supervision of a licensed veterinarian, and at least one of the new animal drugs in the combination is a VFD drug.
FARAD has put together a comprehensive list of approved combinations of medically important VFD drugs for cattle, poultry and swine found under the Code of Federal Regulations (CFR) Part 558 Subpart B ‐ Specific New Animal Drugs for Use in Animal Feeds. These lists contain drugs under the Veterinary Feed Directive and are restricted by Federal law to only be used by or on the order of a licensed veterinarian.
