Coccidiosis declines in commercial feedyards since Rumensin introduction

Rumensin was first approved by the U.S. Food and Drug Administration for feedlot cattle to improve feed efficiency. 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 animal6.

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 reduction6. As seen in the table below, coccidiosis has declined in feedlots since the introduction of Rumensin.
