Electrolytes horse supplements

Dehydration can be a serious health concern for horses.

A horse can lose vital minerals during sweating, working, extreme cold and stress. These lost minerals, also called electrolytes, play a very important role in the health of a horse.

Electrolytes are important

A balance of electrolytes needs to be maintained in the body fluids of a horse.

This balance is important for the transmission of nerve impulses and the normal functioning of nervous, muscle and circulatory systems. Electrolytes play a pivotal role in large number of cell chemical reactions. 

How a horse loses electrolytes

Even when a horse is at rest it loses electrolytes through feces, urine and breathing. Due to excessive sweating, electrolytes are an even more important consideration in an event horse.

It has been found that one liter of horse sweat contains around 3.5 g of sodium, 1.2 g of potassium, 6 g of chloride and 0.1 g of calcium.

Normally, a horse loses around five liters of sweat every hour even at a moderate pace. On a normal day, this may result in the loss of around 50 grams of electrolytes.

Lost electrolytes need replaced

Consumption of hay and other feed doesn’t contain needed electrolytes. Therefore, supplemental electrolytes are needed. A salt lick will provide sodium, but other electrolytes are neglected.

Apart from water, a horse’s sweat contains sodium, potassium, magnesium, calcium, chloride and trace mineral electrolytes.

Horses are not able to store these electrolytes, making it all the more important to include them in their daily intake.

Conclusion, electrolyte supplements for horses

Equine electrolyte supplements improve a horse’s performance, aid recovery after strenuous exertion and help to prevent dehydration.

Increased work and temperature will make a horse sweat more, requiring a higher amount of electrolytes to be replaced.

If electrolyte and fluids are not restored, it can affect the performance of the horse.
