Horse Care - Feeding

A horse or pony needs approximately 1.5% to 2.5% of its body weight in food per day, depending on its age and level of work. This may include forages such as grass or hay and concentrates such as grain or commercially prepared pelleted feeds. Like people, some horses are "easy keepers" and prone to obesity, while others are "hard keepers" and need a great deal of food just to maintain a slim build. The average riding horse weighs roughly 1,000 pounds (450 kg), but the weight of a horse can be more closely estimated using a weight tape, which can be purchased from a feed store or tack shop.

Best practice is to feed horses small quantities multiple times daily, unless they are on full-time pasture. Fresh, clean water should be provided free choice at all times, unless there is a specific reason to limit water intake for a short period of time.

A horse that is not ridden daily or subjected to other stressors can maintain adequate nutrition on pasture or hay alone, with adequate water (10–12 gallons per day minimum) and free access to a salt block or loose salt. However, horses and ponies in regular work often need a ration of both forage and concentrates.

Horses that are fed improperly may develop colic or laminitis, particularly if fed spoiled feed, subjected to excessive feed, or an abrupt change of feed. Young horses who are improperly fed may develop growth disorders due to an imbalance of nutrients. Young horses may also develop osteochondrosis if they are overfed. Regularly monitoring the horse's body condition score on a regular basis assists in helping the horse maintain proper weight.
