Whenever the temperature rises and the threat of performing in extreme heat is a reality people start thinking about electrolytes. Horses can loose immense quantities of electrolytes like sodium, potassium and magnesium through profuse sweating. Ensure your horse has adequate reserves through feeding electrolytes for a few days before and after your event.
The purpose of this Blog is not to tell you how to feed electrolyte, but how to recognize a good electrolyte.
1) Check the ingredient list.
The first ingredient should be Sodium Chloride (salt).
The second should be Potassium Chloride.
Third is typically a magnesium compound like Magnesium Citrate.
From here in in there will be other micro mineral ingredients depending on the manufacturer.
2) There should not be SUGAR in any form. Dextrose, Sucrose, Fructose, Lactose etc. Sugar is not an electrolyte and in some cases can actually draw fluids out of the body into the intestines instead of moving fluids and minerals into the body.
If the label shows a sugar compound as one of the main ingredients, keep on shopping!
3) If you cannot get access to an electrolyte your next best move would be to force feed salt in the grain portion of your horses diet. Manufactured feeds contain salt but typically not in levels sufficient to meet the needs in high temperature stress conditions. Under high temperature conditions when you expect your horse to sweat to a significant degree it would be reasonable to force feed up to 2 ounces of salt a day.
A salt block won't do the job. To get 2 ounces of salt a day by licking is just not a reasonable expectation.
You can use anything from table salt to loose livestock salt. Blue, red, brown or white makes no difference.
