Horse Electrolyte Management in Endurance

Electrolyte management during endurance events is critical for horse welfare, with dehydration and electrolyte imbalance causing serious health problems in competing horses.

Key Facts

Endurance horses can lose 5-10% body weight in sweat during competition
Electrolyte loss includes sodium, chloride, potassium, calcium, and magnesium
Synchronous diaphragmatic flutter from calcium imbalance causes welfare emergencies
Veterinary checks at mandatory stops assess hydration and metabolic welfare
Training and acclimatisation support electrolyte management capacity

Welfare Considerations

Electrolyte imbalance during endurance competition causes acute metabolic welfare emergencies including metabolic tying up and synchronous diaphragmatic flutter. Pre-competition electrolyte supplementation and mandatory veterinary checks protect competing horse welfare.

What You Can Do

Ensure competing horses receive appropriate electrolyte supplementation before and during events
Accept mandatory veterinary welfare checks as essential safeguards for competing horses
Withdraw horses showing metabolic signs rather than continuing competition
