Water Requirements of Horses
Water is an important ingredient of the horse’s diet, since it is crucial for proper function of the body. This “nutrient” makes up 65 to 85 percent of a foal’s body weight, and about 68 to 72 percent of an adult horse’s body weight. A 1000 pound horse’s body contains about 80 gallons of water. Even small changes in total body water can have a negative impact on a horse’s health and well being. Water is contained within all body cells, between cells, and is an important component of blood, joint fluid and lymph.
