Horses with electrolyte imbalances show early signs of fatigue, which translates into lower exercise resistance and loss of performance.
The loss of electrolytes can even compromise the recovery from a state of dehydration, since when there is a loss of electrolytes along with the loss of water, the perception of the need for water intake (what we commonly call ?thirst?), could be compromised.
What to look for when supplementing with electrolytes?
When looking for a complementary food compound (commonly called "supplement") of electrolytes on the market, one should favor formulations whose main ingredient is sodium chloride. Other ingredients that are a source of potassium, calcium and magnesium should also be part of the composition. Added sugar confers palatability to the product, but should not take precedence in the formulation.
Care to be taken when administering electrolytes?
The use of electrolyte formulations should be based on individual recommendations, however there are general good practices to respect.
Permanent access to water
Electrolyte depletion is usually accompanied by water loss (dehydration), so electrolyte replacement should be accompanied by water intake. Even one of the benefits of this electrolyte intake will be the stimulation of water intake.
Administer specific supplementation
If an electrolyte supplement is administered in water, an extra bucket of water without electrolytes should be provided so that the horse can drink water if it cannot tolerate the taste of electrolytes. In case the administration is in the food, it must be mixed well to make sure that it was ingested.
REHIDRAMAX
When intense sweating is expected (for example before a competitive event) a specific formulation should be administered 2 hours before it, and about 1 hour after the effort, ensuring free access to water in both situations.
HORSEBOOSTER
Avoid excess electrolyte supplementation
Excess sodium chloride should be avoided, as it can interfere with blood pressure or stimulate the production of molecules that signal renal sodium excretion (accentuating the imbalance).
Additionally, excessive use of electrolytes may be harmful to the oral or gastric mucosa. It is recommended to wash the horse's mouth, particularly when the administration is done orally using a syringe; and administering the supplement when the horse has food in its stomach.
