Did you think about it? How much urine should a horse produce per day?

Substances such as excessive amounts of salts, especially sodium, and certain medications can harm the kidneys. Inadequate water intake and chronic stress can also increase the risk of kidney dysfunction. The exact amount of daily horse urine varies depending on the horse's size, activity level and diet. On average, a horse produces about 25 to 50 liters of urine per day. Adequate water supply is important to support kidney function and minimize the risk of kidney problems.
