Daily water intake deserves more attention than it usually gets, because dehydration is a leading trigger for colic, and colic is the leading cause of death in domestic horses. The baseline is about 5 litres per 100 kg of body weight, so 25 litres a day for a 500 kg horse standing still in mild weather. Intense work multiplies that by two and a half. Heat above 35°C adds most of another 80%. A horse working hard on a hot day can want four times its resting figure, and the trough was sized for the resting figure.

Hay requirements run from 1.5 to 2.5% of body weight in forage per day, then add waste, which is the part people leave out. Feeding on the ground wastes 15 to 30% of every bale. A hay net cuts that to 5 to 10%, and across one winter the difference pays for a lot of nets.

Blanket sizing and saddle fit work from measurements taken on the horse, not from breed averages.
