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

CAUTION: Do not allow horses or other equines access to formulation containing Monensin. Ingestion of Monensin by equines has been fatal. Monensin medicated cattle and goat feed is safe for use in cattle and goats only. Consumption by unapproved species may result in toxic reactions. Feeding undiluted or mixing errors resulting in high concentrations of Monensin has been fatal to cattle and could be fatal to goats. Must be thoroughly mixed in feeds before use. Do not feed undiluted. Do not exceed the levels of Monensin recommended by 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.

CAUTION: This feed contains added copper. Do not feed to sheep or other related species.
