Synovex Choice® receives additional label indication for dry lot cattle

PARSIPPANY, N.J., — Zoetis announced today it has received an expanded label approval from the Food and Drug Administration's Center for Veterinary Medicine (CVM) for Synovex Choice® to increase rate of weight gain in growing beef steers or heifers in the dry lot production phase. Also approved is a new implant from Zoetis, Synovex® Primer™ that will be available for the dry lot market later in 2024.

“This approval provides beef producers with dry lot operations another tool to help them meet their production and profitability goals,” said John Hallberg, DVM, PhD, U.S. director of regulatory affairs, Zoetis. “As the first trenbolone acetate (TBA) implants approved for dry lot production, steers and heifers have the opportunity to gain additional weight with the appropriate nutritional inputs.”

Effective immediately, existing packages of Synovex Choice can be used in the dry lot production phase. Animal health product suppliers and cattle producers will begin seeing packaging for Synovex Choice with the updated indications by the end of 2024.

“This provides an opportunity for cattle producers with dry lot operations to incorporate a TBA implant in their program to help the cattle grow frame and put on lean muscle,” said Bryan Bernhard, PhD, nutritionist with Zoetis beef strategic technical services. “Dry lot operations have two main goals: get cattle healthy and get cattle growing. By adding Synovex Choice in the dry lot phase, cattle can gain more pounds before they go to the next phase, whether it is grazing or confined feeding.”
