Appropriate electrolyte supplementation supports horse welfare during exercise and hot weather by maintaining fluid balance and preventing heat stress and exhausted horse syndrome.
Electrolyte management is a subtle but important component of welfare for working horses, particularly in hot conditions or during prolonged exercise. Electrolyte deficits impair muscle function and thermoregulation in ways that may not be immediately apparent as clinical signs. Incorrect electrolyte use without adequate water access causes welfare harm through worsening dehydration. Endurance competitions in particular demand sophisticated electrolyte and hydration management from crew members to prevent metabolic emergencies. Veterinary education of event riders and crews on electrolyte physiology improves horse welfare at competition.
