These cattle drugs will be impacted by VFD

These cattle drugs will be impacted by VFD
Use of these animal health antimicrobials in cattle will be impacted by the Veterinary Feed Directive by year-end.

As reported in "Time to chat with your vet", FDA's Veterinary Feed Directive will dramatically change the availability of medicated feed additives by year-end. And, you'll be required to seek veterinary approval for many over-the-counter antimicrobial drugs.

FDA is eliminating all food animal growth promotion uses of "medically important" antimicrobials – ones used to treat human disease. Remaining animal health uses meeting FDA's "judicious use" standards will require your veterinarian's approval.

Here's a current read on how the directive will affect products used in cattle. Keep in mind that the list may grow longer by year-end.

These cattle drugs will be impacted by VFD

• A VFD won't be required to use monensin (Rumensin) in your rations if it's the only "antibiotic" in the ration. It's not considered a medically important antibiotic.

• Many cattle feeders feed tylosin to control liver abscesses. You'll need a VFD to continue doing so, and also for the monensin plus tylosin combination.

• Milk replacers often contain neomycin and oxytetracycline. They'll require a VFD.

• If you own a beef operation in different states, a VFD must be prepared by a veterinarian practicing in the state where the animals are receiving the drug.

• Chlortetracycline and oxytetracycline are often added to the feed in "receiving rations" for feedlot calves to control Bovine Respiratory Disease. They're listed as medically important drugs so a VFD will be required.

• Use of generic products varies by product, and likely requires a VFD. Check with your veterinarian.

• After December 31, 2016, you'll still need a VFD for "leftover" products that previously didn't require a VFD.

• Chlortetracycline isn't approved as a feed additive to control foot rot outbreaks, so it won't be allowed. It's approved for use for anaplasmosis though, and you can request a VFD.
