Managing intake — when less equals more

Rumensin is a proven management tool that protects your investment by increasing the selling weight of your stockers while preventing and controlling coccidiosis.

GREENFIELD, Ind.: Nov. 21, 2008 — As you know, with record high input costs, now is the time to maximize management techniques to increase gain in cattle. Producers who want additional gain per acre of pasture need to constantly evaluate their supplementation programs. Proper management and choosing the right supplement is the key. Now more than ever is the time to make supplementing your cattle a priority.

Why use supplements?

Rate of gain plays an important role in the profitability of a stocker or backgrounder program.1 When producers increase stocking rates, gain is reduced due to lack of forage available per head; therefore, feeding a supplement allows producers to stabilize stocker performance and customize their operation each season.2

Rumensin®: eat less & gain more

Rumensin’s mode of action increases the production of propionic acid by rumen microbes,3 which results in increased animal performance. Supplementing your cattle with Rumensin delivers 20 pounds or more per head of additional selling weight during a 100-day grazing period.4 Therefore, supplementing with Rumensin helps stockers gain more on less mineral.

“For generations, producers have been trained to target 4 oz/hd/d of mineral consumption as a rule-of-thumb. And they worry when consumption falls below that,” says Dr. Doug Hufstedler, Elanco technical consultant. “However, there are exceptions — cattle consuming mineral with Rumensin routinely eat less than 4 oz/hd/d, yet gain more than contemporaries supplemented with a non-medicated mineral. In the end, it’s a win-win situation for producers — reducing mineral consumption while increasing gain/acre.”

Oklahoma State University research shows that stocker cattle receiving a mineral supplement containing Rumensin consumed less mineral, thus reducing supplementation costs without negatively impacting performance. In fact, the cattle supplemented with a Rumensin mineral outperformed all other groups, delivering improved average daily gain and increased profitability.5

Mineral consumption

Proper management of mineral consumption is essential to optimize animal performance and economics. Keep the following tips in mind:

Place mineral feeders in loafing and watering areas

Increase the number of available mineral feeders

Protect mineral feeders from adverse weather

Rumensin is available for stocker cattle in complete feeds, supplements, blocks or free-choice mineral. Ask your Elanco representative, animal health distributors, nutritional supplier or veterinarian to help you maximize your profitability with Rumensin. For more information, visit www.elanco.us.

Dosage/use levels

For increased rate of weight gain: Feed 50-200 mg/hd/day of Rumensin in at least 1 lb of Type C Medicated Feed. Or, after the 5th day, feed 400 mg/hd/day every other day in at least 2 lbs of Type C Medicated Feed. The Type C Medicated Feed must contain 25-400 g/ton of Rumensin.

For the prevention and control of coccidiosis: Feed Rumensin at a rate to provide 0.14-0.42 mg/lb of body weight per day up to 200 mg/hd/day. The Type C Medicated Feed must contain 25-400 g/ton of Rumensin.

Free-choice supplements: 50-200 mg/hd/day of Rumensin.
