We’ve all heard the saying “You can lead a horse to water, but you can’t make them drink.” Horses have to be thirsty in order to consume water, and the lynchpin in that scenario is salt. Dehydration in horses–or any animal–can quickly escalate from mild to catastrophic. Their internal environment is water-based, and salt is the driving force behind the regulation and distribution of water in and out of cells.
“Salt is 39% sodium and 61% chloride. When consumed, salt will split in the body into the separate minerals to be used independently (as electrolytes),” said Dr. Kathleen Crandell, PhD, a nutritionist with Kentucky Equine Research (KER). “Both these minerals have independent roles in the body, but mainly they work together balancing fluid movement in and out of the cells and acid-base balance, as well as electrical impulse conduction in nerves and muscles. Further, sodium is needed for transport of substances across cell membranes, like glucose.”
