Rumensin®

Improves feed efficiency and prevents coccidiosis in beef cattle.

Feedlot: Rumensin® — adding more profit to the bottom line.

Improves feed efficiency and prevents coccidiosis in feedlot cattle.

Since 1976, cattle producers have relied on Rumensin® to improve feed efficiency and prevent coccidiosis. And for 40 years, Rumensin has demonstrated proven results, and continuous innovation, adding more profit potential to the bottom line.

Rumensin is a cost-effective feed additive that improves feed efficiency by 4 percent1 by providing more energy from the ration through increased glucose supply.2 Feeding Rumensin also reduces dry matter intake and improves average daily gain.3

For the prevention and control of coccidiosis, Rumensin® is the most potent feed ingredient available4 that kills coccidiosis parasites at three different stages in the life cycle instead of merely slowing their development.5 It's more efficacious at lower doses compared to other ionophores.4

The prevalence of Coccidiosis has declined in commercial feedyards since it was introduced in 1975. Rumensin® was first cleared by the U.S. Food and Drug Administration for feedlot cattle in 1975 to improve feed efficiency. Throughout 1976, cattle feeders started adopting Rumensin® in their commercial feedyards, and found the prevalence of coccidiosis started to decline. At that time, coccidiosis was one of the most detrimental diseases, with estimated costs averaging $54.25/infected animal.6

From 1974 to 1982, the annual death loss from coccidiosis in Kansas and Nebraska feedlots dropped from 55–60 deaths/100,000 cattle to fewer than five deaths/100,000 cattle over the eight-year period—a 92 percent reduction.6
