Belgian Drafts are among the largest horse breeds in the world, and their nutritional demands reflect that scale. An adult Belgian can weigh anywhere from 1,800 to over 2,200 pounds, which means they require significantly more forage and calories than light horse breeds. Their metabolism, however, tends to be relatively efficient, so overfeeding can be just as dangerous as underfeeding. Striking the right balance is critical for maintaining healthy weight, strong hooves, and sustained energy for work or recreation.
The foundation of any Belgian Draft's diet should be high-quality forage. Hay or pasture grass should make up the majority of their daily intake, generally around 1.5 to 2 percent of their body weight. For a 2,000-pound Belgian, that translates to roughly 30 to 40 pounds of hay per day. Good-quality grass hay is typically preferred over rich alfalfa, which can provide excessive protein and calories for a draft horse that is not in heavy work.
Belgians that are actively working, whether pulling, plowing, or competing in draft shows, will need additional caloric support beyond forage alone. Concentrates or grain mixes designed for working horses can fill that gap, but they should be introduced gradually and portioned carefully. Draft horses are prone to certain metabolic conditions, so monitoring body condition score on a regular basis is essential to ensure the diet is meeting their needs without pushing them into excess.
Water intake is another factor that deserves attention. A Belgian Draft can drink 10 to 15 gallons of water per day under normal conditions, and significantly more during hot weather or periods of hard work. Clean, fresh water should be available at all times, and electrolyte supplementation may be warranted during heavy sweating to replace lost minerals.
