  1. Mare’s Milk Plus should be mixed with cool tap water and stirred with a wire whisk.

  2. Mare’s Milk Plus should be fed at room temperature and does not require warming prior to ingestion.

  3. Start by feeding your foal half of the recommended volume from the table and gradually increase the amount over the next 10 days until the recommended amount is reached.

  4. Always discard any milk not consumed prior to adding fresh.

  5. Mare’s Milk Plus should be mixed every 12 hours; however, a 24-hour supply can be mixed if necessary. One half can be fed, and the other half covered and stored in a cool place until the next feeding (does not require refrigeration).

  6. Always keep equipment clean to avoid the risk of infection.

  7. Provide clean, fresh water always.

  8. Occasional diarrhea may occur in foals fed milk replacer. When this happens, reduce the amount of Mare’s Milk Plus by 25% and then gradually increase until the foal is consuming the recommended amount. If diarrhea persists, contact your veterinarian.
