Feeding Instructions

CAUTION: Do not allow horses or other equines access to formulations containing Monensin. Ingestion of Monensin by equines has been fatal. Monensin-medicated cattle feed is safe for use in cattle only. Consumption by unapproved species may result in toxic reactions. Do not exceed the levels of Monensin recommended in the feeding directions as reduced average daily gains may result. A withdrawal time has not been established for pre-ruminating calves. Do not use in calves to be processed for veal. Consumption of selenium should not exceed 3 mg per head per day.

Feeding Recommendations:

  1. To be fed free choice at the rate of 3.2-8 oz. of block per head daily. This will provide 80-200 mg Monensin per head per day.
  2. Feed 1 block per 5 head of cattle. This allows all animals equal access to blocks.
  3. Place blocks where animals congregate. Locate blocks throughout pasture, placing them near water and loafing areas. Maintain adequate distance between blocks (10 ft. minimum).
  4. Do not allow animals to run out of blocks. When a block is half-consumed, place a new block near it. Place very small pieces in troughs or feed pans.
  5. Feed as the only FREE CHOICE source of salt, minerals and vitamins.
  6. The effectiveness of this block in cull cows and bulls has not been established.
