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. Monensin, commonly referred to by its brand name, Rumensin, is an ionophore which targets gram-positive bacteria in the rumen. By reducing the gram-positive bacteria, the gram-negative bacteria are allowed to thrive. This leads to a shift in volatile fatty acids in the rumen in the favor of propionate, which is more efficiently used by cattle. In the US, monensin (trade name "Rumensin"- manufactured by Elanco Animal Health) is a feed additive for cattle indicated "for improved feed efficiency, for increased rate of weight gain, and for the prevention and control of coccidiosis caused by Eimeria bovis and Eimeria zuernii". In growing beef steers and heifers on pasture, 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.1 For pennies per head per day, Rumensin delivers 20 lbs or more per head of additional selling weight during a 100-day grazing period.1 Because feed comprises over 80% of the cost of producing fat cattle, considerable research has been directed towards improving utilization of the energy in feeds by ruminants. Attempts to get more energy from cattle feeds have included grinding, pelleting, steam flaking, feeding ensiled high moisture grains and feeding high concentrate rations.
