Registered indications

Rumensin 100 Premix is registered for:

• Improved weight gain and feed efficiency
• For improved reproductive performance in heifers
• As an aid in the prevention of coccidiosis caused by Eimeria zuernii and E. bovis.

Proven performance benefits

Rumensin is a proven way of improving feed efficiency and growth rates in grassfed beef cattle. Dozens of scientific trials involving thousands of cattle and conducted throughout the world have found that the addition of Rumensin to supplementary feed can increase weight gains by 70–120 g/head/day (6–16%), regardless of the energy and protein level of the supplement.(1 – 4) Just as importantly, these liveweight gains were achieved without any significant increase in supplementary feed intake. Trials conducted at Swans Lagoon Research Station have demonstrated the addition of Rumensin to typical dry season molasses and urea supplements can improve liveweight gains by up to 70% and feed conversion efficiency by up to 59% compared to cattle fed standard molasses and urea rations.(5,6) In one trial, Rumensin increased liveweight gain by 42% yet reduced molasses and total feed intake by 12% and 16%, respectively.(6)

How Rumensin works

Rumensin is a naturally-derived product which alters the composition of the microbial population in the rumen. In effect, it increases the production of propionic acid, the most efficient of the volatile fatty acids needed for milk production and growth. Put simply, this means more energy in the feed is made available to the animal from every mouthful consumed, regardless of feed intake or the level of supplementary feeding. Besides increasing feed efficiency, the active ingredient in Rumensin reduces methane gas production and the build-up of foam in the rumen associated with bloat. Rumensin also exerts powerful anticoccidial activity.

Feeding instructions

Rumensin 100 Premix should be thoroughly mixed with other feed components to achieve an effective dosage rate of 100–200 mg monensin/head/day. Always read the label directions before use.
