Ultium Gastric Care

Consistency is Key
Horses thrive on consistency, but there’s nothing consistent about competition: performance schedules are anything but predictable, new neighbors arrive in adjoining stalls, and arenas and environments are constantly changing. This inconsistency can take a toll- affecting health, attitude, and performance. In fact, even common activities including stall confinement, exercise, and transportation are known to cause stress in horses, which may challenge their immune systems and can lead to gastric discomfort.
Purina® Ultium® Gastric Care horse formula helps equine athletes during the stress of competition by providing optimal gastric and immune support.

Purina® Ultium® Gastric Care horse formula was developed by Purina’s Ph.D. Equine Nutritionists and Veterinarians to provide consistent support during times of stress. This feed is the culmination of decades of Purina equine nutrition research, and contains specialized ingredients designed to support a healthy gastric environment and immune system.

Balanced Nutrition to Support Overall Health 

Formulated by Purina Ph.D. Equine Nutritionists using only high-quality ingredients, Ultium® Gastric Care horse feed is designed to meet the daily protein, vitamin, and mineral needs of equine athletes.

Consistent Nutrition in Every Bag

Purina's Constant Nutrition® formulation process makes small adjustments in the amount of ingredients to compensate for nutrient variability. This process helps ensure that your horse receives consistent nutrition in every bag.

*This is the recommended minimum amount of hay to be fed. If feeding more hay, reduce the feeding rate of ULTIUM® GASTRIC CARE FORMULA by 1.0 lb for every additional 2.0 lbs of hay fed.

** Do not feed less than 0.3 lbs per 100 lbs of body weight per day to meet minimum protein, vitamin and mineral requirements for maintenance. If your horse gains too much weight at that minimum feeding rate, then you should replace ULTIUM® GASTRIC CARE FORMULA with a lower calorie PURINA® Horse Feed option or PURINA® ENRICH PLUS® Ration Balancing Horse Feed, and supplement with PURINA® OUTLAST GASTRIC SUPPORT SUPPLEMENT.
Follow label directions. Feeding added selenium at levels in excess of 0.3 ppm in the total diet is prohibited. 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. USE ONLY AS DIRECTED
