Elanco Animal Health reports that the Food and Drug Administration (FDA) has granted approval for feeding Rumensin to dairy cows in component-feeding systems, and has expanded the Rumensin label to allow feeding to dairy replacement heifers raised in drylots.
Component-feeding systems include supplements that are fed in the parlor, in electronic feeders or as a topdress.
The new label for Rumensin has updated mixing and feeding directions for these supplements, which the FDA calls Type C medicated feeds, Elanco says. In addition, the directions now include individual-cow ranges for Rumensin feeding, with levels from 185 mg/hd/day to 660 mg/hd/day approved for lactating cows and from 115 mg/hd/day to 410 mg/hd/day approved for dry cows.
"These label changes provide added flexibility and helpful guidelines when feeding Rumensin to increase milk-production efficiency," says Howard Green, dairy technical alliance manager, Elanco Animal Health.
Nutritionists and producers may continue to feed Rumensin to lactating and dry cows in TMRs at a rate of from 11 g/ton to 22 g/ton on a 100 percent dry matter basis, the company adds.
The FDA also has expanded the Rumensin label to allow feeding to dairy replacement heifers that are raised in drylots. The feeding directions for heifers remain the same.
