The Best Salt Block For Horses

Many new horses and livestock owners are surprised to learn their animals need salt. After all, salt is an essential nutrient which the body is not capable of producing. Luckily we have done our research to help you choose the best salt block for horses. The sodium and chloride in salt are what the horses need for optimal health. Sodium assists with protein digestion, muscle contractions, and nerve impulses. The chloride primarily maintains the pH balance of blood but also increases the efficiency in carbon dioxide transportation to their lungs.  Horse sweat is also hypertonic, meaning it contains more salts than fluid. It is necessary to replenish these electrolytes, so salt intake is very important.

Purpose of Salt Block for Horses

Although horses receive some trace vitamins and minerals through grazing, grass and hay contain minimal sodium. Salt blocks were created as a sodium chloride source for horses and the most common form of supplementation. However, owners may notice added salt in concentrated hay cube formulas. On average, horses need 1-2 ounces of salt per day. This can greatly increase (upwards of 6 ounces per day) if horses are working and sweating in great quantity.

 

Unless forcefully administered by humans, horses will not naturally consume an over-abundance of salt. Salt toxicosis may be possible but usually occurs when water is extremely limited or completely inaccessible. A more likely scenario would be a salt deficiency. This can occur over a time span of several weeks or months. Deficiency symptoms include pica (eating unnatural or foreign things the animal wouldn’t normally touch) and frequent licking of anything that may have salt. If the deficiency is allowed to progress and remains uncorrected, horses may suffer from weight loss, dehydration, and loss of appetite in extreme cases.

Use

Salt blocks are best used as a “free-choice” item. This means horses should have daily access to blocks, but under normal circumstances does need to be intentionally fed or administered. Horses’ salt requirements are innate, and they will consume an appropriate amount if made available. Salt blocks are available in several varieties and sizes. There are specialty pans sold for salt block use, like this one here.

How to Select a Salt Block

Size and location are major factors in selecting a salt block. Some owners keep larger blocks in the pasture or turnout, while others have stall blocks. Typically, free access to any type of salt lick will be adequate for horses. However, if horses are unable to get an appropriate amount from licking, they will begin to chew the block.

Larger blocks are well-suited for pasture availability. Owners should ensure they are kept in an open area where all horses can access the block without becoming trapped by more senior herd members. Many horses enjoy a community salt block. However, weathering and temperature conditions can decrease the amount a block is utilized when out in the open without protection. Other horse owners prefer smaller stall blocks or even Himalayan rock salt ropes, so salt intake or usage can be easily monitored. This also ensures each horse has readily available access to salt as opposed to a shared pasture setting.

Types of Salts

Plain Salt

Salt blocks can be trace-mineralized or plain. The plain white salt blocks only contain sodium chloride. This is the most popular salt block, as it is a no-frills plain salt option.

 Himalayan Salt

Himalayan rock salt is unprocessed. Although it does contain other minerals (both good and bad), the trace amounts are so minute it does not typically affect your horse in a positive or negative manner. Therefore, Himalayan salts are typically referred to as plain salts. However, the pink color is actually due to the mineral content. They are easy to hang and the texture is gentler on a horse’s tongue despite how hard they are. Because of the texture, they are more weather resistant than other salt blocks.

Trace Mineral Blocks For Horses

Trace mineral blocks contain sodium chloride and trace minerals like copper, zinc, iron, iodine, and manganese. Although there is not a significant amount of trace minerals, they can be beneficial if local soil/forage lacks trace minerals. Some red mineral blocks will also have added selenium, which many areas lack.

Alternatives

Salt blocks are not the only means of supplemental salt. However, salt licks are greatly preferred because it is a free-choice item. Although adding salt to feed allows owners to directly control salt intake, it removes the horse’s innate ability to consume the required amount. Some owners opt to feed loose salts if they notice their horse is starting to chew on a traditional salt block. Other owners choose to supplement with electrolyte formulas. These typically contain salt, calcium, potassium, and magnesium. Most electrolyte formulas are available in appealing flavors and can be given over food.

Closing Thoughts

Pasture limitation and stabling can create many challenges in horse ownership. However, horses in captivity do not have different nutritional needs just because they are stabled. Fortunately, there are many great products on the market to help supplement horses’ salt needs and daily intake requirements.

The final salt product chosen is typically a matter of preference. The product must not only meet storage needs (in a stall, hanging, or in a pasture pan) but must appeal to the horse. Many “all species” blocks will not entice horses enough to encourage licking. Between the availability of salt blocks, mineral blocks, and feed dressings, you are sure to find the right solution for your animals.
