Chemistry is a branch of physical science that studies the composition, structure, properties and change of matter.
Daily water consumption varies quite a bit. Season of the year, workload, reproductive status, diet, and climate factor into the volume of water needed by a particular horse on a specific day. As a starting point, the average horse drinks between 5 and 10 gallons (19 and 38 liters) of water each day. The horse may need slightly less if it is grazing lush pasture because fresh grass contains a high percentage of liquid.
Horses need to eat 1-2% of their total weight in hay, and drink 1-2% of their body weight in water, every day. If a horse weighs 1,000 pounds, he needs at least 10 pounds of hay or grass forage everyday to maintain his weight, or 1% of his total weight. That means, at any time of the day, approximately 1-2% of the horseâs weight is food and water being pushed from the foregut to hindgut. The more exercise or calories burned, the more the horse will need to eat to maintain his âfigureâ.
