The VFD: New Information for

 Large Animal Producers



The medications involved are considered antibiotics that are medically important in human medicine.


Per dvm360, “A report from the FDA released in December 2015 states that most antimicrobial drugs approved for use in food animals are marketed for use in feed (74 percent) or water (22 percent). Furthermore, the report indicates that 97 percent of these drugs are dispensed OTC, or without veterinary supervision.”


Important changes to look out for starting January 1, 2017:

  • Antibiotics can't be used for growth promotion. They can only be used to treat, control, or prevent bacterial diseases.

  • Any antibiotic listed as “medically important” will require a VFD to be used in feed or water.


VFDs will include an expiration date and a duration of use for the antibiotic. This is determined by product labeling and your veterinarian, but cannot exceed 6 months regardless.


You the producer, your veterinarian, and your feed distributor must keep records for two years.


In order for a VFD to be written, you must have a valid relationship with a veterinarian. It is illegal for a veterinarian to dispense or write a VFD for animals they are unfamiliar with.
