The Rumensin Advantage

Rumensin (monensin) is a proven management tool that optimizes your investment by improving cattle weight gain and feed efficiency, even as the quality of forage changes from year to year.1 Rumensin is the only ionophore approved for use in all production phases in the beef industry.

When you choose Rumensin, you can trust that it is better suited for feed mixing with2:

  • Better particle-size distribution
  • Less variability
  • Less dust

The findings from more than 400 Elanco research studies have made it possible for producers to include Rumensin in ever-changing food programs and management systems.

Implementing Rumensin

The impact Rumensin has on performance is detailed for the different stages of production in the figure below. To maximize feed efficiency throughout the production cycle, Rumensin can be fed in any diet.

Rumensin for coccidiosis prevention and control

For coccidiosis prevention and control, Rumensin is the most potent feed ingredient available that kills coccidiosis parasites at three different stages in the life cycle3,4 instead of simply slowing their development. Additionally, it more efficacious at lower doses compared to other ionophores.

Since 1975, cattle producers have relied on Rumensin (monensin, USP) as a trusted solution that helps deliver proven results year after year. The legacy continues with service offers and Elanco’s commitment to generating value.

To be successful feeding dairy beef steers for market it’s essential steers be fed a properly balanced ration that promotes rapid and efficient growth. Higher energy, no roughage diets provide the greatest opportunity for maximum performance and profitability when feeding dairy steers. Kent Precision Dairy Beef supplements provide high levels of vitamins, minerals, and proteins that are limited in corn-based diets.

Features and Benefits

  • Simple feeding program
  • Whole shelled corn eliminates processing
  • Less equipment and labor needed
  • No roughage required
  • Fast economical gains
  • Rumensin provides feed efficiency
  • Yeast may help stimulate intake and rumen metabolism
  • Sodium diacetate: an acetic acid ingredient may help stabilize rumen pH
  • ZinPro® organice trace mineral nutrition may help improve key performance factors including average daily gain, feed conversion, and hoof integrity
