Preparing for Prescription

While another month has come and gone for the 2023 production year, if you haven't already heard, June will hold some significant changes for the livestock industry.

When it comes to livestock antibiotics, many products that have typically been used over-the-counter will now need a veterinary prescription.

"Just as physicians have started to try and educate people to not utilize antibiotics in those cases, we're really trying to have the same conversation with the livestock industry," says Mike Lormore, DVM, head of technical services over pork and cattle for Zoetis.

On June 11, the FDA's Guidance for Industry (GFI) #263 will take effect, bringing 91 over-the-counter antimicrobial products under prescription oversight.

While the sales of antimicrobial injectables in 2021 declined by 11% from 2016, Lormore says the FDA's guidance is a result of a long conversation around improving the quality of and control systems around antimicrobial use in food production.

The guidance applies to all food animals, including cattle, hogs, ruminants (goats/sheep) and poultry. In addition, it also applies to animals not intended for food, such as horses, pet rabbits and backyard chickens.

"While this change does not require the purchase of products from a veterinarian, going forward, producers will be legally required to obtain a prescription from a licensed veterinarian with whom the producer has a valid veterinary-client-patient relationship," says Becky Funk, DVM, and Jesse Fulton in a University of Nebraska-Lincoln article.

Specifically, the veterinary-client-patient relationship (VCPR) is a mutual agreement between the animal owner and the veterinarian where the veterinarian has an understanding of the animals on an operation, the type of care they're given on a regular basis, their purpose, and the risk factors associated with management of those animals, Lormore explains.

If you do not have a relationship with a veterinarian, start visiting with a local practitioner so they can become familiar with you and your animals on your operation.

Additionally, Linda Tikofsky, DVM and senior associate director of dairy professional services at Boehringer Ingelheim says, "I think the number one thing to do is just take inventory of what you’re using and what you won't be able to purchase after June 2023. Go through your drug cabinet, take note of what you’re using and how often you’re using it."

This will help you prepare for conversations with the veterinarian, discussing standard operating procedures and routine drug orders.

For beef producers using growth-promoting implants, additional changes will be taking place in June.

While implants are labeled for sex, age or stage of production, until recently, implant labels did not include directions for reimplantation within the production stage for which they are intended, Sandy Stuttgen, DVM, senior outreach specialist and Taylor County Extension agriculture educator with the University of Wisconsin Extension.

To bring clarity, the FDA has defined specific production stages, which will be used to determine if and when a growth-promoting implant can be administered.Beef cattle will still be allowed to receive multiple implants across different stages of production, including each of the following phases defined by FDA GFI 191:• Beef Calves: 1) Pre-ruminant or ruminant beef calves nursing their dams from birth until 2 months of age 2) Ruminating and nursing their dams from 2 months of age to weaning• Growing beef steers or heifers on pasture (stocker, feeder or slaughter): weaned and maintained on pasture and receiving most of their diet from grazing• Growing beef steers or heifers in a drylot: weaned and maintained in a dry lot and fed harvested forage (possibly with supplement)• Growing beef steers or heifers fed in confinement for slaughter: weaned growing and finishing animals confined in group pens or grow yards and fed progressively high-energy diet ad libitum as their sole ration until slaughter

Overall, as a good practice in administering any vaccine or implant, Stuttgen encourages producers read the product label and lean on your veterinarian to determine how the products should be best used in the operation.
