FDA Approves New HeifermaX Two- And Three-way Feeding Combinations

The U.S. Food and Drug Administration (FDA) has approved the use of HeifermaX® with Rumensin® at its elevated dose of up to 40 g/ton (90 percent dry matter) in two- and three-way feeding combinations for feedlot heifers.

The approved combinations include a two-way combination with HeifermaX and Rumensin and a three-way combination with HeifermaX, Rumensin and Tylan®. The new combinations will allow for enhanced heifer performance, as Rumensin’s elevated dose improves feed conversion by 0.05 lbs feed/lb of gain (P< 0.01)1 when compared to the 30 g/ton dose.

“Producers now have the flexibility to manage heifers for feed optimization and efficiency using the complete portfolio of Elanco feed ingredients,” said Travis Choat, PhD, Elanco beef technical director.

An easy-to-use liquid premix, HeifermaX increases weight gain, improves feed efficiency and suppresses estrus (heat) in feedlot heifers. It has no pre-harvest withdrawal required in the United States, which offers cattle feeders more marketing flexibility while improving heifer performance for a better bottom line.

For all products: The label contains complete use information, including cautions and warnings. Always read, understand and follow the label and use directions.

HeifermaX: Heifers fed in confinement for slaughter
For increased rate of weight gain, improved feed efficiency and suppression of estrus (heat): Feed 0.5 to 2.0 lb/hd/d of melengestrol acetate in a Type C medicated feed to provide 0.25 to 0.5 mg/hd/d.

Tylan: For the reduction of incidence of liver abscesses: Feed continuously at 8 to 10 g/ton of tylosin (90% DM basis) to provide 60 to 90 mg/hd/d.

Rumensin: Cattle fed in confinement for slaughter
For improved feed efficiency: Feed 5 to 40 g/ton of monensin (90% DM basis) continuously in a complete feed to provide 50 to 480 mg/hd/d. No additional improvement in feed efficiency has been shown from feeding monensin at levels greater than 30 g/ton (360 mg/hd/d).
For the prevention and control of coccidiosis: Feed 10 to 40 g/ton of monensin (90% DM basis)  continuously to provide 0.14 to 0.42 mg/lb of body weight/d of monensin up to a maximum of 480 mg/hd/d.
