Huvepharma® announces FDA-approval for cattle feed additive Optigrid® 45 (ractopamine hydrochloride Type A medicated article)

Global animal health company Huvepharma® has received FDA-approval for Optigrid® 45, a feed additive used to promote weight gain and improve feed efficiency in finishing feedlot cattle.Optigrid® 45, which is comprised of the active ingredient ractopamine hydrochloride, is a bio-equivalent product to Optaflexx® and can be fed as a complete feed or top dress feed to cattle fed in confinement for slaughter during the last 28 to 48 days on feed prior to harvest. When fed as a complete feed, ractopamine hydrochloride can also promote increased carcass leanness.

“In today’s challenging world with the continued need for efficiency in beef production, we are pleased to bring further medicated feed additive options such as Optigrid® 45 to the cattle industry,” says Glen Wilkinson, president of Huvepharma, Inc. (U.S.).

Wilkinson adds, “Optigrid® 45 adds another choice from Huvepharma’s expanding product line and is a continued example of our commitment to bring our core strength in medicated feed additives to the U.S. animal food producing industry. Huvepharma’s product development, regulatory, and sales teams are dedicated to providing effective and essential animal health products to the livestock industry.”
