What Does Plenty of Water Do for Your Horse's Body and Function?

Last updated 4 years ago

Did you know that a horse’s body is approximately 50-80% water? A constant supply of clean fresh water is essential when it comes to good horse care. How much water does your horse need for a healthy diet? Consider what plenty of water can do for your horse’s body and overall functioning abilities.

Determining Amount of Water

A horse generally requires 5 liters of water per 100 kilograms of bodyweight per day; this means that a 900lb horse should have approximately 3-6 gallons a day, while a 1500lb horse will require anywhere from 5-10 gallons. There are several factors that may influence the amount of water required by your horses, including outside air temperature, work load, grass vs. dry feed, overall size, and health of the horse. Pregnant or nursing horses will also require more water than other horses.

Water and Brain Function

Water plays a crucial role in both hearing and vision function. The inner ear contains fluid that vibrates in response to sound waves, sending nerve impulses to the brain. The eyeball, which is predominantly water, is continually bathed in fluids from the lachrymal gland. The horse’s hypothalamus, or gland located at the base of the brain, controls their body’s use of water by secreting antidiuretic hormones (ADH) into the body; when ADH is released, the cells retain water. Water also bathes and cushions the brain and central nervous system, lubricating all of the body’s moving parts.

Temperature Regulation

Similarly to humans, horses sweat as a natural defense against warm temperatures; however, the lack of water can lessen the amount of sweat being excreted, making it difficult for the horse to lower their body temperature.  Water is also essential in order to maintain electrolyte balance and prevent dehydration, as this can lead to serious health conditions.

The best way to ensure that your horse is being property hydrated is to invest in a horse water trough or automatic horse waterer. For the best livestock troughs, horse troughs, and livestock waterers available anywhere, visit Bar-Bar-A today!
