Also note the size of the horse's stomach. Because it is small compared to the horse's size, many classes of horses are not able to consume enough forage to meet their nutrient requirements. Therefore, you need to provide concentrates and increase feeding frequency to support proper growth, development and performance. All horses require a good, clean source of fresh water daily for normal physiological function. Clean the water buckets and tanks frequently, removing algae and other foreign material.
Water deprivation is more common in winter than summer because of freezing temperatures.
Make every effort to ensure that water sources do not freeze, because with most species of animals water deprivation causes death quicker than starvation. Therefore, it is extremely important that a clean fresh source of water be supplied to horses at all times. Energy Energy is what horses use to do work. Their energy requirements are influenced by age and by the work's degree and duration. Young, growing horses, horses at high work intensities and lactating mares have the greatest requirement for energy.
