*These recommendations are based on the mare eating the minimum recommended amount of hay per day of 1.2 pounds per 100 pounds of
 body weight. If feeding more hay, reduce the feeding rate of Omolene #300® horse feed by 1 pound for every additional 2 pounds of hay fed.

** Do not feed less than 0.35 pounds per 100 pounds body weight per day.

*** Use lower feeding rate for moderate growth rate and higher feeding rate to support more rapid growth.

Suckling foals: Begin offering feed. Feed 1 pound of Omolene #300® horse feed per month of age per day. 700-pound weanlings: For horses with expected mature weight of 1,000 pounds or who are 12 months of age, change to Omolene #200® horse feed and feed as directed.

Best Results
  • Feeding rates will vary with size, age, temperament, health status, forage quality,climate and activity level. Feed at regular times – at least twice daily – with three daily feedings preferred. Let horses feed in a natural position from troughs with large bottoms, placed at normal head height or lower. Do not feed free-choice. Prevent the rapid eating by the horse of any feedstuff.
  • Reduce and/or delay feeding a horse which is hot, excited or showing pain, has fever or diarrhea. Consult your veterinarian if any problems arise.
  • Always feed a minimum of 1.0 to 1.2 lbs per 100 lbs of body weight of good quality,clean hay or the equivalent in pasture.
  • Any feed changes should be made gradually over a period of 7 to 10 days. Changes in the rate of feeding should not exceed 1.0 lb per day for each horse.
  • Have plenty of clean, fresh water available at all times. Provide your horse with access to salt. Maintain an effective control program for internal parasites. Have the horse’s teeth examined annually and consult your veterinarian on a regular basis.
Changing To
  • Make the feed change gradually over a period of 7 to 10 days.
  • Mix the new feed with the old, gradually increasing the amount of the new feed while decreasing an equal amount of the old.
  • Changes in the rate of feeding should not exceed 1 pound per day for each horse.
Store in a dry, well-ventilated area protected from rodents and insects. Do not feed moldy or insect-infested feed to animals as it may cause illness, performance loss or death.
