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.
