Domestic Settings

Horses in domestic environments face challenges in obtaining sufficient salt intake compared to their wild counterparts. Pasture grass and typical feed might not always contain adequate levels of sodium and chloride to fulfill a horse’s daily requirements. Furthermore, domesticated horses might not have access to natural mineral deposits, limiting their ability to self-supplement.

Recommended Salt Intake

To compensate for the limitations in acquiring salt naturally, horse owners typically provide salt supplements or mineral blocks in domestic settings. This supplementation ensures that horses receive the necessary sodium and chloride levels to maintain optimal health and performance. Different forms of salt supplements are available, including loose salt, salt blocks, or mineral mixes tailored for equine needs.

Understanding the disparity between how wild and domesticated horses obtain salt underscores the importance of providing appropriate supplementation in a domestic setting to meet the specific mineral requirements of horses, ensuring their overall health and well-being.

Signs of Salt Deficiency in Horses


Insufficient salt intake can lead to decreased thirst response in horses, potentially resulting in dehydration. Signs of dehydration include sunken eyes, lethargy, dry mucous membranes, and decreased skin elasticity.

Reduced Appetite

Horses deficient in salt might display a decreased interest in food, leading to reduced feed intake. This decline in appetite could result in weight loss or a decrease in overall body condition.

Muscle Cramps or Weakness

Salt deficiency can affect a horse’s muscle function, leading to muscle cramps, weakness, or trembling. These symptoms may manifest during exercise or even at rest.

Dull Coat and Lack of Energy

Inadequate salt levels might contribute to a horse having a lackluster coat or a rough, unkempt appearance. Additionally, a salt-deficient horse might display decreased energy levels or appear fatigued even with minimal exertion.

Behavioral Changes

Horses experiencing salt deficiency may display behavioral changes such as irritability, restlessness, or unusual nervousness.
