Both of my horses are in Florida and the temperatures have been so high, but I just want to make sure that they’re getting enough to help them manage the heat. They each have salt licks in their stalls and my one horse is retired and my other I ride about 4x a week and lately he’s been dripping sweat after our ride. I’ve been giving them each purina replenimash every day and about 30-60 minutes after ride days. Is that enough electrolytes? Is that product considered an electrolyte supplement.
Replenimash provides almost 8gm sodium and almost 11gm chloride per pound
Salt is generally about 11gm sodium and about 17gm chloride per ounce, so the Replenimash is providing a bit less than that.
As a baseline, an 1100lb horse needs 10gm sodium and 40gm chloride just to sit around and so nothing
It does provides some of the other e-lytes, probably good enough for your purpose
If they’ll eat it, add at least 1tbsp plain white salt, per 500lb body weight, daily to their feed. Divided into each feed, assuming 2+, is best, especially since a lot of horses won’t eat 2+tbsp in a meal (mine will, thankfully) They may not be getting enough from the salt lick
Most of what’s in sweat is salt, so I’d focus on increasing their known intake
