In feedyards, Rumensin improves feed efficiency by providing more energy from the ration.1 Research demonstrates that Rumensin improves feed efficiency by 4% and provides a net return of $23.13/hd.2

On pasture, Rumensin improves feed efficiency in beef cows, reducing their feed requirements 5% to 10% while maintaining body weight with no negative impacts on reproductive performance.3 Rumensin also improves average daily gain in replacement heifers, resulting in fewer days to first estrus — which can result in improved lifetime productivity.4

For only pennies per head per day, you can sell heavier stocker and backgrounder cattle. Rumensin is a proven management tool that optimizes your investment by improving cattle weight gain, even as the quality of forage changes from year to year.2

For the prevention and control of coccidiosis, Rumensin is the most potent feed ingredient available5 that kills coccidiosis parasites at three different stages in the life cycle instead of merely slowing their development.6 It's more efficacious at lower doses compared to other ionophores.5

dairy

Cows have different needs at different stages of lactation. Early-lactation cows crave additional energy to support higher milk production. Their late-lactation counterparts need less feed to maintain production and pregnancies.

Regardless of the feedstuffs for lactating and dry cows, Rumensin helps cows get more energy from every pound of feed.

For the prevention and control of coccidiosis in dairy replacement heifers and calves, Rumensin is the most potent feed ingredient available1 that kills coccidiosis parasites at three different stages in the life cycle instead of merely slowing their development.2 It's more efficacious at lower doses compared to other ionophores.1

For all products: The label contains complete use information, including cautions and warnings. Always read, understand and follow the label and use directions.

Rumensin
CAUTION: Consumption by unapproved species or feeding undiluted may be toxic or fatal. Do not feed to veal calves. The label contains complete use information, including cautions and warnings. Always read, understand and follow the label and use directions.

Rumensin: Cattle fed in confinement for slaughter For improved feed efficiency: Feed 5 to 40 g/ton (90% DM basis) continuously in a complete feed to provide 50 to 480 mg/hd/d.

For the prevention and control of coccidiosis due to Eimeria bovis and Eimeria zuernii : Feed 10 to 40 g/ton (90% DM basis) continuously to provide 0.14 to 0.42 mg/lb of body weight/d, depending upon severity of challenge, up to a maximum of 480 mg/hd/d.

Rumensin: Growing cattle on pasture or in dry lot (stockers, feeders, and dairy and beef replacement heifers) For increased rate of weight gain: Feed 50 to 200 mg/hd/d in at least 1.0 lb of Type C medicated feed. Or, after the 5th day, feed 400 mg/hd/d every other day in at least 2.0 lbs of Type C medicated feed. The Type C medicated feed must contain 15 to 400 g/ton of monensin (90% DM basis). Do not self-feed.

For the prevention and control of coccidiosis due to Eimeria bovis and Eimeria zuernii: Feed at a rate to provide 0.14 to 0.42 mg/lb of body weight/d, depending upon severity of challenge, up to a maximum of 200 mg/hd/d. The Type C medicated feed must contain 15 to 400 g/ton (90% DM basis).

Free-Choice (Self-Fed) Medicated Feeds: Approved supplements must provide not less than 50 nor more than 200 mg/hd/d of monensin.

Rumensin: Mature reproducing beef cows

For improved feed efficiency when receiving supplemental feed: Feed continuously at a rate of 50 to 200 mg/hd/d. Cows on pasture or in dry lot must receive a minimum of 1.0 lb of Type C medicated feed/hd/d. Do not self-feed.

For the prevention and control of coccidiosis due to Eimeria bovis and Eimeria zuernii: Feed at a rate of 0.14 to 0.42 mg/lb of body weight/d, depending upon severity of challenge, up to a maximum of 200 mg/hd/d.

Rumensin: Calves (excluding veal calves)

For the prevention and control of coccidiosis due to Eimeria bovis and Eimeria zuernii: Feed at a rate of 0.14 to 1.0 mg/lb of body weight/d, depending upon severity of challenge, up to a maximum of 200 mg/hd/d. The Type C medicated feed must contain 10 to 200 g/ton of monensin (90% DM basis).

For Dairy Cows: For increased milk production efficiency Total Mixed Rations (complete feed): Feed continuously to dry and lactating dairy cows a total mixed ration (“complete feed”) containing 11 to 22 g/ton monensin on a 100% dry matter basis.

Rumensin Component Feeding Systems (including top dress): Feed continuously to dry and lactating cows a Type C Medicated Feed containing 11 to 400 g/ton monensin. The Type C Medicated Feed must be fed in a minimum of 1 pound of feed per cow per day to provide 185 to 660 mg/head/day monensin to lactating cows or 115 to 410 mg/head/day monensin to dry cows. This provides cows with similar amounts of monensin they would receive by consuming total mixed rations containing 11 to 22 g/ton monensin on a 100% dry matter basis.
