Rumensin is a rumen modifier. Rumen modifiers modify the rumen environment, which in turn modifies the composition of the microorganisms. Rumensin favours the microorganisms that produce propionate – energy, and reduces the microorganisms that produce waste – methane. This means Rumensin improves feed conversion efficiency. Therefore, at the same level of feed intake, animal production will be improved.

It also prevents Coccidiosis, scours. Young animals are prone to Coccidiosis, especially during the weaning process as a result of stress, weaker health systems due to rumen functioning changes and differences in the feed quality. Coccidiosis, in severe cases can cause severe sickness and death, hence the need for prevention.

Note: Rumensin is toxic to horses. Feeding Rumensin to horses or other equines may be fatal.
