When does a horse need a salt lick
Almost everyone has a salt block hanging in their horse's stall. But does the horse actually lick it? And is that enough in the summer, when it returns drenched in sweat after a workout?
Salt is the only substance that a horse craves instinctively and that is almost never found in sufficient quantities in hay alone. In this article, you will find out how much they need, when their requirements spike, and why a single block in the stall doesn't always solve the issue.
Why salt is not a trivial matter for a horse
Sodium and chlorine, the two components of salt, are responsible for processes that occur every second:
- fluid balance in the body
- transmission of nerve impulses
- muscle contraction
- the sensation of thirst
The last point is the most important and most frequently overlooked. If a horse lacks salt, it stops feeling thirsty. It stops drinking. And then a chain reaction begins: the blood thickens, the intestines function less effectively, and the risk of colic increases.
Hay and pasture provide very little sodium. This is not a question of feed quality; it is simply almost absent in plants.
How much salt is actually needed
For an adult horse at rest, the base requirement is about 10 grams of salt per 100 kg of body weight per day. For an average 500 kg horse, this is approximately 50 grams, or about two tablespoons.
But that is only the starting point. When working, a horse loses salt through sweat, and it loses a lot. A horse's sweat is saltier than a human's, so after intense work, the requirement can double or even triple.
When the need is especially high
- Summer heat, when they sweat even while standing
- Intense work, especially endurance, show jumping, and long rides
- Transportation, when stress and stuffiness in the trailer are added
- Competitions, where both stress and physical load play a role
- Lactating mares, because some minerals are lost in the milk
Why a block in the stall is not always enough
A classic pressed salt block is hard and smooth. A horse's tongue, unlike a cow's, is soft, so it is difficult and time-consuming for them to lick the required amount from such a surface.
In practice, two extremes are observed. Some horses barely touch the block and remain deficient. Others, once a deficiency has already formed, attack it and gnaw on it. This is a sign that they should have started sooner.
There is also a third point that is considered less often: a salt block cannot be the only source of minerals. Simple white salt provides only sodium and chlorine, not magnesium, potassium, or trace elements.
What to choose
Loose salt for the feed
The most reliable method when you want to know the exact amount. Add it to the feed and mix. The downside is that the horse cannot regulate it itself, so you have to monitor the amount.
A lick with salt and herbs
An intermediate option that works better than a pure block. The softer texture allows the horse to actually get the salt, and the herbal supplement provides more than just sodium.
A lick with Himalayan salt and anise is designed for exactly this. Himalayan salt makes up 21.44% of the composition, while star anise and caraway are traditionally used for digestive comfort.
An added benefit is that the licking keeps them occupied. The horse is not just standing in the stall; chewing and licking stimulate saliva, which helps the stomach.
Both one and the other
The most practical approach: loose salt in the feed according to need, and a lick left as a constantly available supplement. Then the horse gets the base and can take more itself when the need arises.
How to notice that salt is lacking
- drinking less than usual
- licking walls, fences, dirt, or sweaty hands
- gnawing on the salt block greedily instead of licking it calmly
- taking longer to recover after work, appearing lethargic
- drier manure
Excess, on the other hand, is almost harmless to a horse, provided there is always clean water nearby. A healthy horse eliminates excess salt through urine.
The only condition is water. Salt without constantly accessible water is dangerous. This is a rule without exceptions.
In short
Salt is not a treat or a "if you remember" supplement. It is a daily requirement that increases several times over in the summer and after work.
If a horse barely touches a salt block, it doesn't mean it doesn't need it. More often, it means it is too hard for them to get it. A softer lick or loose salt in the feed solves that problem.
And always check the simplest thing: is the water trough full, is the water clean, and is it frozen in winter?
