Feeding Directions

Mix at the rate of 25 pounds to 50 pounds of this Add Pak along with grain and forages to provide 11 to 22 grams per ton of monensin per ton of dry matter.


CAUTIONS: Do not allow horses or other equines access to formulation containing Monensin. Ingestion of Monensin by horses has been fatal. Monensin-medicated cattle and goat feeds are safe for use in cattle and goats only. Consumption by unapproved species may result in toxic reactions. Do not feed to lactating goats. 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. A withdrawal time has not been established for pre ruminating calves. Do not use in calves to be processed for veal.

LIMITATIONS: Feed continuously to dry and lactating dairy cows in a total mixed ration. You may notice:


  1. Reduced voluntary feed intake in cows fed Monensin. This reduction increases with higher doses of monensin fed. Rule out Monensin as the cause of reduced feed intake before attributing to other causes such as illness, feed management, or the environment.

  2. Reduced milk fat percentage in dairy cows fed monensin. This reduction increases with higher doses of Monensin fed.

  3. Increased incidence and treatment of cystic ovaries and metritis in dairy cows fed monensin.

  4. Reduced conception rates, increased services per animal, and extended days open and corresponding calving intervals in dairy cows fed monensin. Have a comprehensive and ongoing nutritional, reproductive and herd health program in place when feeding Monensin to dairy cows.
