Horses with electrolyte imbalances show early signs of fatigue, which translates into reduced exercise resistance and loss of performance.
The loss of electrolytes can even compromise 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 to drink water (what we commonly call “thirst”) may be compromised.
What to look for when supplementing with electrolytes?
When looking for a complementary compound food (commonly known as a “supplement”) of electrolytes on the market, you should prioritize formulations whose main ingredient is sodium chloride. Other ingredients that are sources of potassium, calcium and magnesium should also be part of the composition. Added sugar makes the product palatable, but should not take precedence in the formulation.
What precautions should be taken when administering electrolytes?
The use of electrolyte formulations should be done based on individual recommendations, however there are general good practices to follow.
Permanent access to water
Electrolyte depletion is generally accompanied by water loss (dehydration), so electrolyte replacement should be accompanied by water intake. In fact, one of the benefits of this electrolyte intake is that it stimulates 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 does not tolerate the taste of electrolytes. If the supplement is administered in food, it should be mixed well to ensure that it has been ingested.
REHIDRAMAX
When intense sweating is expected (for example before a competitive event), a specific formulation should be administered 2 hours before the event and approximately 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 the renal excretion of sodium (accentuating the imbalance).
Additionally, excessive use of electrolytes may be harmful to the oral or gastric mucosa. It is recommended to rinse the horse's mouth, particularly when administration is done orally using a syringe; and to administer the supplement when the horse has food in its stomach.
