Best Results
  • Omolene #400® horse feed is designed to be fed as a complete feed because it's formulated with high-quality roughage. If necessary, you may also feed with good-quality hay or pasture, up to a maximum of 5 pounds per day, to relieve boredom.
  • Reduce the amount of Omolene #400® horse feed fed by 1 pound for every 1.75 pounds of hay offered.
  • For best results, do not feed more than 1 pound of hay per 100 pounds of your horse's body weight when feeding Omolene #400®horse feed.
  • Feeding rates will vary with size, age, temperament, health status, 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.
  • 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.
