Aug 04, 2022

By Kathleen McGinty

Zoetis announced today it has received expanded label approval from the Food and Drug Administration’s Center for Veterinary Medicine (CVM) on three beef implant products. Synovex Choice^® is the foundation of new reimplant labels that are now available to feedlot operations, which also include Synovex Plus^® and Synovex^® One Feedlot.

“This approval provides beef producers with enhanced flexibility to more broadly use these technologies to help them meet their production and profitability goals,” said John Hallberg, DVM, PhD, U.S. director of regulatory affairs, Zoetis. “The performance benefits of Synovex Choice, Synovex Plus and Synovex One Feedlot have long been proven and this is the logical next step for the industry.”

These three products are approved for reimplanting programs in both steers and heifers fed in confinement for slaughter. The three reimplantation labels include:

Synovex Choice followed by Synovex Choice, 60 to 120 days later
Synovex Choice followed by Synovex Plus, 60 to 120 days later
Synovex Choice followed by Synovex One Feedlot, 60 to 120 days later

Effective immediately, existing packages of Synovex Choice, Synovex Plus and Synovex One Feedlot can be used in reimplanting programs at feedlots. Animal health product suppliers and cattle producers will begin seeing updated labels with the approved reimplantation language by the end of 2022.
