There’ve been a lot of changes in the cattle industry over the last 40 years. Advanced genetics, improved nutritional programs and better animal health all add up to more production and efficiency per animal. Throughout it all, producers continue to trust Elanco's Rumensin® (monensin) to deliver consistent, dependable results.

TIMELINE
LEGACY OF PROGRESS

Once Rumensin was introduced in 1976, cattle producers had an FDA-approved feed ingredient that helped them improve feed efficiency. Soon after, Rumensin was approved to help prevent and control coccidiosis.

Continuous innovation and research has led to Rumensin being approved for use in dairy and beef replacement heifers, beef cows, calves and in dairy cows, helping dairy producers increase milk production efficiency by delivering more milk per pound of feed.

Production of marketable solids-corrected milk per unit of feed intake.
