Frequently Asked Questions (FAQs)

1. Do horses need electrolyte supplements?

Horses can typically obtain enough electrolyte minerals from a forage-based diet with added plain table salt for extra sodium and chloride. However, horses on high grain/low forage diets or those needing additional potassium may benefit from electrolyte supplements or the addition of potassium chloride to their feeds.

2. How do you replenish electrolytes in horses?

The most effective way to replenish electrolytes and water in horses is by providing an isotonic solution. Products like Restore SR and Restore Paste, available through KER, are designed to match a horse's sweat content, helping to restore electrolyte balance and hydration effectively.

3. Can you give too much electrolytes to horses?

Yes, it is possible to overdose a horse with electrolytes, which can lead to fatal sodium imbalances. It is crucial to never give electrolytes to a horse without ensuring they have access to fresh, plain water and to never exceed the recommended dosage.

4. What electrolytes can you put in water for horses?

Aviform Electroform EQ Equine Electrolytes is a fast-acting electrolyte supplement that contains optimal ratios of sodium, chloride, potassium, magnesium, calcium, MSM, glucose, and vitamin C. It can be administered in water or feed and is known for its palatability and ease of use.

5. How do you make electrolyte water for horses?

To make electrolyte water for horses, you can add 45g of table salt and 45g of Lo-Salt to 10 liters of water. This creates a 0.9% solution or 90g of electrolytes in 10 liters, which is similar to normal electrolyte losses in sweat.

6. Should I give my horse electrolytes or salt?

It is generally recommended to provide both electrolytes and salt for horses. However, the preference and tolerance for saltiness in their mash may vary among horses. It is advisable to consider electrolytes only when the horse already has a good sodium balance or under the guidance of a veterinarian.
