Along with the water, various electrolytes and trace elements are also lost with the sweat. The elimination of these substances in sweat is extremely constant. Even with high sweat loss, the composition of the sweat remains unchanged.

If the water, electrolyte and active substance concentrations are unbalanced and inadequately replaced following extended exertion, the animal can show signs of exhaustion. It is therefore very important after exertion that working animals are not only provided with water, but also that the loss of electrolytes is made good. If the electrolytes are provided in dissolved form as well, they are rapidly and completely absorbed by the organism, thereby reducing the time needed for regeneration.
