Zoetis announced today that Synovex® Primer™ is now available for cattle producers who need to increase weight gain in growing beef steers or heifers in the dry lot production phase. The Food and Drug Administration’s Center for Veterinary Medicine (CVM) approved Synovex Primer earlier this year, along with an updated label indication for Synovex Choice® in the dry lot.

Synovex Primer is a low-dose combination product with 50 mg of trenbolone acetate (TBA) and 7 mg of estradiol benzoate. Research demonstrated that Synovex Primer significantly increased average daily gain at 2.47 lbs./head/day (p = 0.0016) when compared with the sham implanted group at 2.21 lbs./head/day over the course of the 90-day study.1

“The addition of Synovex Primer to our implant portfolio gives producers options in the dry lot space,” said Bryan Bernhard, PhD, nutritionist with Zoetis beef strategic technical services. “From dry lot to pasture to confined feeding operations, the portfolio of Synovex implants allows beef producers to dial-in the dose of TBA over the animal's lifetime and choose a Synovex implant that matches the available nutrition and performance goals.”
