When you think about it, all mammals are made up largely of salt and water, i.e. salt water. Drinking water is essential for all of life’s functions. Even at rest, a horse needs to drink 2-4 pints of water for every pound of food consumed. An intake of 20 pounds of hay means a horse must drink a minimum of 7-½ gallons of water.
The food your horse eats is converted into energy fuel to drive locomotion. Approximately 70 – 80 % of this energy conversion is wasted as heat, which is dissipated from the inner recesses of the horse’s body as sweat. Horses sweat three times as much as a human per a given surface area of skin. While a person may shed two liters of sweat in an hour, a horse might evaporate or drip away 15 liters in that same hour.
Exercise brings the need for water to a whole new level. For support of maintenance requirements for basic bodily functions, an exercising horse must also replenish body water that is lost in sweat from exercise. The ability to cool the body during locomotion relies on sufficient blood circulation, which is dependent on a horse’s level of hydration.
Along with water loss through sweat is depletion of as much as 10% of a horse’s total body stores of electrolytes. Imbalances and loss of fluids and electrolytes have significant impacts on normal function of skin for sweating, muscles for locomotion, and the intestines for digestion. Loss of too much “water” and electrolytes can lead to reduced performance along with significant clinical problems.
It’s true that you can lead a horse to water but you can’t make him drink but are there strategies that might stimulate…
