1. Veterinary Feed Directive
Dr. Whitney Whitworth
Lyssy & Eckel Feeds

2. Not a new concept Animal Drug Availability Act (ADAA) enacted in 1996
Prior to that, only two options for dispensing drugs, over the counter & prescription
Drug companies were asked to revise their labeling to remove claims of growth promotion and feed efficiency in December 2013
Created the veterinary feed directive (VFD) drugs
Final rule into effect October 2015
Full implementation January 1, 2017

3. Why?
Congress recognized that certain drugs should only be administered under veterinarian’s order and professional supervision
There needed to be controls over certain antimicrobials
Control necessary to reduce overuse of drugs and to prevent bacterial resistance
Also difficulty in diagnosis or toxicity issues

4. What is a VFD?
Written statement issued by a licensed veterinarian that orders the use of a VFD drug or combination VFD drug in or on an animal feed
Feed can only be fed to animals on the written VFD for the specified time
Veterinarians must have knowledge of the animal, its health, the facilities it is housed in and be available for any follow-up evaluation and care

5. Information required on a VFD
Veterinarian’s name, address & phone number
Client’s name, address and phone number
Premises which the animals in the VFD are located
Date of VFD issuance
Expiration date of the VFD
Name of the VFD drug
Species and production class of animals to be fed
Approximate number of animals to be fed the VFD by the expiration date

6. Information required on a VFD, contd.
Indication for which VFD issued
Level of VFD drug in feed and duration of use
Withdrawal time, special instructions, and cautionary statements
Number of reorders authorized, if permitted by the drug approval, conditional approval or index listing
The statement: “Use of feed containing this veterinary feed directive (VFD) drug in a manner other than as directed on the labeling, is not permitted”
Affirmation of intent for combination VFD drugs
Veterinarian’s signature

7. VFD may include the following
More specific location of the animals
Approximate age range of the animals
Approximate weight range of the animals
Other information appropriate in identifying the animals

8. Special Considerations
Street address is usually sufficient for location, but GPS may be necessary
More detailed descriptions may be necessary
Animals managed similarly in different locations may fall under the same VFD
No feed in a VFD can be fed after the expiration date
Expiration date will not exceed 6 mo after date of issuance
Based on calendar date, not number of days
Duration of use may also be specified
If a drug has multiple approved concentrations, veterinarian may authorize a particular level or the entire range of approved dosages
All parties (veterinarian, client, distributor) must keep a copy of the VFD for two years

9. Special considerations, contd
No extra label use is allowed
Veterinarian must send VFD to distributor in hard copy or electronically
If the VFD expires before you have fed all of a VFD feed, you must get a new VFD.

15. Difference between a VFD and a prescription

Written so that there would be oversight of important drugs without infringing on pharmacy laws
