  • 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.
