The medical profession has alerted us to the woes of using too much salt on our food. So, you are probably careful how much salt you add to your food. Do not let this human concern invade management practices for your horses.
Horses require salt in their daily diet.
The typical horse ration of forage and grain does not provide adequate salt for the average horse. This need becomes more critical in hot, humid weather, especially in performance horses but even for horses on pasture only. So, do not neglect salt for your horse this summer. Dried salt crystals can be observed over the backs and hips of idle or maintenance horses in pasture. This loss of salt must be replaced.
