Warning: A withdrawal time has not been established for this product in pre-ruminating calves. Do not use in calves to be processed for veal.

Caution: Do not allow horses or other equines access to feeds containing Monensin. Ingestion of Monensin by equines has been fatal. Monensin-medicated cattle feeds are safe for use in cattle only. Consumption by unapproved species may result in toxic reactions. Do not feed undiluted. Feeding undiluted or mixing errors resulting in high concentrations of Monensin has been fatal to cattle and could be fatal to goats. Do not exceed the levels of Monensin recommended in the feeding directions as reduced average daily gains may result. If feed refusals containing Monensin are fed to other groups of cattle, the concentration of Monensin in the refusals and amount of refusals fed should be taken into consideration to prevent Monensin overdosing. Do not feed to sheep or other copper-sensitive animals.
