The U.S. Food and Drug Administration (FDA) has approved new combination uses of Zoetis’ feed additives ACTOGAIN 45 (ractopamine hydrochloride) and ENGAIN (ractopamine hydrochloride).

Beef producers, together with their veterinarians and nutritionists, will now be able to use ACTOGAIN 45 in combination with Rumensin (monensin USP) plus Tylovet 100 (tylosin phosphate).  ACTOGAIN 45 also has been approved for concurrent use with Rumensin plus Tylovet 100 plus MGA (melengestrol acetate).

Pork producers, veterinarians and nutritionists may now use ENGAIN together with Tylovet 100. These combinations have previously been approved with Tylan (tylosin phosphate).

“As part of our on-going antibiotic stewardship efforts, we want to help offer our customers more approved solutions,” said Marilyn Corbin, DVM, MS, Ph.D., Strategic Beef Technical Services Veterinarian at Zoetis. “These new approved combinations will help meet producers’ animal health needs in an ever-changing regulatory environment by offering more flexibility in using these types of products.”
