What are electrolytes?
Electrolytes are minerals — sodium, potassium, chloride, calcium and magnesium — that are essential for muscle function, nerve conduction and fluid balance. Horses lose significant amounts through sweat.
How much does a horse lose?
A sport horse can produce 10 to 15 litres of sweat per hour during intensive exercise. This sweat contains three times more sodium and chloride than human sweat.
When to supplement?
Immediately after exercise is the ideal time. Provide electrolytes with feed or dissolved in water. Repeat the following morning after heavy exercise. Always ensure sufficient fresh drinking water.
Practical tips
- Never give electrolytes to a dehydrated horse without water
- Start supplementation the day before a competition in hot weather
- Regularly check the skin pinch test for hydration
