Warning: Do not supplement monensin from other sources (eg. other feed stuffs containing monensin or the Rumensin Controlled Release Capsule). Keep out of reach of children.


  • Directions for use must be carefully followed.
  • Do not use in association with another feed containing supplemental Selenium.
  • Do not allow dogs, horses or other equines or guinea fowl access to formulations containing monensin.  Ingestion of monensin by these species has been fatal.
  • The 24 g/tonne monensin treatment in primiparous cows may result in the increased incidence of udder edema and increased number of inseminations per full term conception.
  • The continuous use of monensin in dairy cows may be associated with increased rates of twinning and stillbirths, and have heavier birth weights for heifer calves.

Note: Complete diet refers to the complete feed plus the roughage and must be corrected to a 100% dry matter basis.
