Grow stockers and revenue with REVALOR-G.

With a payout proven in real-world grazing periods, REVALOR-G delivers an ROI stocker operators can count on.1

The #1 choice in stocker implants.2

REVALOR-G is used in more stocker cattle than any other brand. In fact, it leads the next closest implant brand by a more than 2-to-1 margin. Here’s why.

REVALOR-G delivers added weight gain for a proven ROI.

Cattle implanted with REVALOR-G while on pasture gain an average of an extra 23 lbs. and maintain the added weight during the finishing period.3

It’s dosed for stockers’ maturity levels.

As animals mature, increased doses in implants are needed to make implants more effective. REVALOR-G matches the hormone level with the production setting to achieve maximum productivity.

It improves grazing performance for 150 days.

The typical stocker grazing period is 150 days5, which is exactly how long REVALOR is designed to last. With REVALOR-G, you only need to implant stockers in the grazing period once.
