FDA-approval granted to Huvepharma® for feed additive CycleGuard® 500 (melengestrol acetate Type A liquid medicated article)

PEACHTREE CITY, GA (June 24, 2020) — Huvepharma® has received FDA-approval for CycleGuard® 500, a melengestrol acetate feed additive used for suppression of estrus in heifers.

Available as a Type A liquid medicated article, CycleGuard® 500 is a bio-equivalent product to MGA® and HeiferMaX®, meaning it provides the same benefits of dosage, chemical identity, potency, quality and safety to these existing melengestrol acetate brands.

CycleGuard® 500 can be used to suppress estrus in heifers intended for breeding as well as to suppress estrus among heifers fed in confinement intended for slaughter. For feedlot heifers, melengestrol acetate is also proven to increase rate of weight gain and improve feed efficiency. CycleGuard® 500 must be mixed with other feeds when fed and be fed according to label directions.

“We are excited to bring more products to the U.S. cattle industry as we continue to rapidly expand our Huvepharma portfolio,” notes Glen Wilkinson, president of Huvepharma U.S. He adds, “Huvepharma is focused on offering quality product choices and technical expertise to livestock producers and feeders to aid the industry in enhancing production and efficiency. CycleGuard® 500 is one more tool available toward that effort.”

Throughout the U.S., Huvepharma is focused on building partnerships with industry customers by offering high quality products and unparalleled customer service.

IMPORTANT SAFETY INFORMATION: CYCLEGUARD® 500 (melengestrol acetate Type A liquid medicated article): Not effective in steers or spayed heifers.  Withdrawal periods of three to five days or more should be avoided to prevent the possibility that the heifers may come into estrus (heat) at loading time. When used in heifers intended for breeding, do not exceed 24 days. A reduced conception rate can be expected within 1 to 12 days after the withdrawal of melengestrol acetate. Heifers bred on subsequent observed estruses will have normal conception rates. To report adverse effects, access medical information, or obtain additional product information, call 1-877-426-7765.
