FDA approves higher dose for Rumensin

The U.S. Food and Drug Administration (FDA) has granted an expanded dose range approval for Rumensin for improvement in feed efficiency and coccidiosis prevention and control in feedlot cattle. The approval increases the upper end of the dose range to 40 grams per ton, on a 90% dry matter basis.

Today, cattle feeders rely on Rumensin - an ionophore used as a feed additive - from start to finish to prevent and control coccidiosis and to improve feed efficiency by providing more energy from the ration. By controlling disease and increasing the efficiency of rumen fermentation, Rumensin reduces feed intake variation - thus improving rumen function and gastrointestinal health.

With the approval, the maximum dose increases to 480 mg/hd/d for feed efficiency for feedlot cattle. For the prevention and control of coccidiosis, the maximum Rumensin dose also increases to 480 mg/hd/d for feedlot cattle.
