The actual daily amount of water that most horses need to consume (at a minimum) to maintain body functions and remain properly hydrated is from a half gallon to a gallon per 100 pounds of body weight.
Horses need a bare minimum of 1% of their body weight in hay or grass each day to maintain gut health and motility. That is a minimum of 10 pounds for a 1000 pound horse. 1.5% is recommended for easy keepers, and closer to 2% is recommended for all others.
