Do Salt Licks Work?

Updated: Aug 28

Does your horse get enough salt from a salt lick?


The system that manages salt intake is about regulating blood pressure. The brain doesn't look at salt in the muscles. When the horse sweats, it uses salt and electrolytes, so while the blood pressure and blood volume may be normal, the horse's system might be telling it that salt is fine, when it's actually deficient. If they have large, rapid sweat losses, the system that regulates salt might take longer to figure that out, because it's looking at blood pressure, not salt and electrolytes in tissues. In short, there is a lag between being deficient and knowing that there's a deficiency.


There is a persistent myth that horses regulate their own salt intake, but all horses like salt. They might eat more than they need because they like it, or because they are bored. As described above, horses in work with regular heavy sweat losses might eat less than they need. A horse in work doubles their salt requirement. A horse in heavy work will need more. A rough guide is an extra 12g of salt per hour of work.


Horses without enough salt can cramp, dehydrate, colic, suffer from heat stroke and generally have poor performance.


Salt is cheap, and palatable. It is very easy to supplement. A good rule of thumb is a tablespoon a day and then an extra tablespoon for a horse in work, or wearing a rug. A horse in heavy work, for example endurance training, will need more again.


Salt licks with other additives are available from the produce store. Many of them contain molasses. Molasses has no nutritional benefit. It's only use is for improving palatability and salt is already palatable. Some of them also contain sulfur. You don't need to add sulfur because it blocks absorption of other important minerals.


For a pleasure horse or retired horse, a Himalayan block is a good option for owners.


For a performance horse, or working horse, adding salt at the required amount to your horse's feed is a more accurate way of ensuring your horse is getting the salt they need.
