Purina® Ultium® Competition Horse Formula

Purina® Ultium® Competition Horse Formula

With Outlast® Gastric Support Supplement

It’s about the moment. The instant when horse and rider face the challenge. Months, years of discipline and training come together. The conditioning, the focus and the will to work in unison. You show up with the determination to win and the power to perform beyond your limits. Winning is defined on your own terms.

Find that edge and you’ve got the competitive advantage. The new generation of trainers and competitors don’t want claims. They want results. Ultium® Competition Horse Formula is highly researched nutrition for the high energy demands of hard-working equine athletes, allowing them to compete at their highest levels. When others hit the wall, your horse keeps going.


Patented, proprietary technology is the culmination of decades of Purina® equine research. Ultium® Competition Horse Formula has been successfully field-tested across a wide spectrum of competitive disciplines.

Unique “pellets and extruded Amplify® nuggets” aim to prevent sorting, reduce waste and transport easily. Highly palatable and digestible, it’s “nutrient dense,” and “highly efficient” so you can “feed less.”

Sustained Energy System® features a unique blend of three (3) fuel sources:
  1. Fat
  2. Fermentable Fiber
  3. Soluble carbohydrates (starch and sugar)
Research in horses has shown that the dietary energy source can influence activity and excitability. Specifically, when compared to concentrates high in starch and sugar, the feeding of a diet higher in fat and fiber but with less starch and sugar helps promote more manageable behavior. Ultium® Competition Horse Formula seamlessly “blends” three fuel sources into a smooth, unbroken “steady” stream of energy. Horses consuming Ultium® Competition Horse Formula will receive more calories from highly digestible fiber sources and vegetable oils, and fewer calories from sugar and starch than if they were being fed a traditional grain based diet. This type of dietary formulation provides the horse with what is referred to as “cool” energy. Studies have shown that certain horses are sensitive to higher levels of sugar and starch in their diet. These horses tend to be less excitable and more manageable when fed lower levels of starch and sugar.

Features & Benefits

Sustained Energy System®

A unique blend of three fuel sources to provide a steady level of highly digestible energy: soluble carbohydrates, fats and fermentable fiber. A horse that is mentally focused, controllable and manageable has the best chance of winning.

Targeted Nutrition Delivery System

Quickly transports repair nutrients where they’re needed most. Unique amino acid profile and top-quality fuel sources replenish glycogen and protein stores in muscles to assist in muscle repair with less muscle fatigue for faster bounce back, competition after competition.

Nutrient and Energy-Dense

Supports prolonged stamina and endurance while maintaining the equine athlete in peak competitive condition. Less feed is required for maintenance of body condition when compared to feeds with lower energy density, helping prevent digestive upset.

Reduced Starch, Higher Fat

May help reduce the risk of colic and other digestive disturbances that can occur when feeding large quantities of grain

Purina® Amplify® High-Fat Nugget

A proprietary blend of vegetable oils, flax seed and rice bran smooths the glucose and insulin response to dietary starch and sugar, leveling out blood sugar levels for a pronounced calming effect.

Precise Amino Acid Profile

For optimal muscle performance and recovery.  Promotes muscle tone and a strong top line.

Highly Fermentable Fiber

Metabolized in the hindgut, providing slow-releasing energy and preserving muscle glycogen. Anecdotal evidence in field tests also indicates Ultium® Competition Horse Formula may be beneficial for horses that have a tendency to “tie up.”

Balance of Vitamins and Minerals

Including B-Vitamins, Iron, Copper, Calcium, Phosphorus and Magnesium: blood-building nutrients that help optimize red blood cell production and increase oxygen capacity in exercising horses. The proper balance of Calcium and Phosphorus promotes stronger bones.

Added Antioxidants

Including Vitamins E, C and Selenium help address the negative effects of free radicals and support a strong immune system.

Concentrate Feed

Designed to be fed with hay or pasture.

Outlast® Gastric Support Supplement

Scientifically shown to support gastric health and comfort and proper pH through the stress of travel and competition.

Feeding Directions

Start with the amounts of Ultium® Competition Horse Formula given for the weight and lifestyle of the horse. After observing the horse for a period, the amount fed may be gradually increased or decreased to obtain the desired body condition and weight. For feeding directions outside the ranges addressed in these feeding charts, please contact your local Purina retailer or Purina Customer Service at 800-227-8941.

* This is the recommended minimum amount of hay to be fed. If feeding more hay, you may reduce the feedingrate of Ultium® Competition Horse Formula to maintain appropriate body condition.
** To meet nutrient requirements, do not feed less than 0.3 lbs. per 100 lbs. of body weight per day for mature horses at maintenance (3 lbs. per 1000-lb horse). If your horse gains too much weight at the minimum feeding rate, transition to Purina® Enrich Plus® Ration Balancing Feed.

NOTE: Feeding rates of Ultium® Competition Horse Formula and forage may be adjusted or feed may be top-dressed with Purina® Amplify® High-Fat Supplement for additional calories. Hard-working horses may also benefit from supplementation with Purina® Supersport® Amino Acid Supplement.

A 4-pound meal of Ultium® Competition Horse Formula supplies a full serving of Outlast® Supplement.
Follow label directions. Feeding added selenium at levels in excess of 0.3 ppm in the total diet is prohibited.
  1. Feeding rates will vary with size, age, temperament, health status, forage quality, climate and activity level. Feed at regular times, at least twice daily. Do not feed more than 0.5 lbs/100 lbs of body weight per meal. Do not feed free-choice. Prevent rapid eating by the horse of any feedstuff.
  2. 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.
  3. 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.
  4. 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.
  5. Provide fresh, clean water at all times. Provide your horse with access to salt. Consult with your veterinarian regularly and maintain a routine dental, parasite control and health care program for your horse.
