Auxois horses require carefully managed nutrition balancing the substantial energy needs of horses weighing 1,600-2,400 pounds against their status as extremely efficient keepers prone to obesity when allowed unlimited feed access. This paradox of massive size combined with easy-keeping metabolism creates significant management challenges, as these horses need adequate nutrition supporting their bulk, energy requirements, and health while avoiding the excessive weight gain that leads to metabolic disorders, laminitis, and other serious health issues common in overfed draft horses. Understanding and implementing appropriate feeding strategies proves crucial for maintaining Auxois horses in healthy condition throughout their lives.
Forage forms the absolute foundation of healthy nutrition for draft horses, with quality hay and pasture providing the bulk of daily intake while supporting proper digestive function. Auxois horses typically require approximately 2-2.5% of body weight in forage daily, translating to 32-60 pounds of hay or hay-equivalent pasture for a 1,600-2,400 pound horse, representing substantial daily forage consumption requiring adequate storage and reliable sourcing. The digestive system of horses evolved for near-constant small-quantity intake of fibrous plant material, making continuous forage availability essential for physical health and psychological well-being. Quality grass hays like timothy, orchard grass, or local grass hays appropriate to the region provide excellent nutrition for most Auxois horses, while legume hays like alfalfa or lucerne offer higher protein and energy suitable only for horses in heavy work or those requiring weight gain, as their richness can quickly lead to excessive weight in easy-keeping draft breeds.
Concentrate feeds including grains, pellets, or commercial feeds should be fed sparingly to Auxois horses, as most individuals maintain excellent condition on forage alone without any grain supplementation even during light work. Their remarkable feed efficiency means they convert forage to body mass extremely effectively, requiring vigilant monitoring preventing the obesity epidemic affecting many draft horses in modern management. When concentrates prove necessary for horses in sustained heavy work, during cold weather when energy requirements increase, or for individuals struggling to maintain weight, feeding should occur in multiple small meals rather than large single feedings, reducing risks of digestive upset including colic and grain overload. Total concentrate feeding rarely needs to exceed 0.5-1% of body weight daily even for working Auxois, with many requiring significantly less or none at all.
Body condition management represents perhaps the most critical nutritional challenge with easy-keeping Auxois horses, as their efficiency at converting feed to body mass means even slight overfeeding accumulates into dangerous obesity over time. These horses should maintain body condition scores of 5-6 on the 9-point scale, appearing muscular and well-covered without excessive fat deposits over ribs, withers, crest, or tail head. Overweight Auxois face dramatically increased risks of laminitis, equine metabolic syndrome, insulin resistance, joint problems, and reduced work capacity, making weight management absolutely essential for their health and longevity. Regular body condition assessment, ideally monthly, allows timely adjustments to feeding programs before significant weight gain occurs, though weight loss in extremely large horses requires very gradual approaches preventing health complications from rapid weight reduction.
Pasture access requires particularly careful management for Auxois horses, as lush spring and fall grass contains high levels of sugars and starches creating metabolic risks for easy-keeping breeds. Grazing muzzles, restricted turnout hours limiting grass intake, or dry lot management with controlled hay feeding may prove necessary during periods of rapidly growing pasture, particularly for individuals prone to weight gain or showing signs of metabolic sensitivity. While limiting grazing access feels counterintuitive given horses' size, allowing unlimited access to rich pasture virtually guarantees obesity and associated health problems in horses as efficient as Auxois at utilizing available feed.
Mineral and vitamin supplementation addresses nutritional gaps in forage-based diets, particularly important in regions where soil mineral deficiencies create corresponding deficiencies in locally grown hay. Commercial vitamin-mineral supplements formulated specifically for draft horses provide balanced nutrition without excessive calories from grain-based feeds. Salt should be available free-choice as loose salt or salt blocks, allowing horses to self-regulate sodium intake based on needs varying with work level, environmental temperature, and individual metabolism. Copper, selenium, and zinc supplementation may prove necessary in deficient regions, though should be based on forage analysis or veterinary guidance rather than routine supplementation, as excesses of certain minerals create health problems equally serious as deficiencies.
Water availability remains absolutely crucial for horses this large, with clean, fresh water accessible at all times supporting digestive health, temperature regulation, and metabolic function. Auxois horses typically consume 40-70 liters daily depending on environmental temperature, work level, and diet composition, with requirements increasing substantially during hot weather or periods of work. Given their size, these horses produce correspondingly large volumes of urine and manure, making adequate water intake essential for preventing impaction colic and supporting kidney function. Water sources must be checked multiple times daily ensuring proper function and cleanliness, as any interruption in water availability creates serious health risks for horses this large.
Special dietary considerations apply to Auxois horses in different life stages and circumstances. Growing young horses require careful nutritional management supporting development without promoting rapid growth creating developmental orthopedic disease, balancing adequate protein and minerals for sound skeletal development against restricting energy intake preventing obesity. Senior Auxois may require more digestible feeds or soaked hay supporting aging-related changes in dental function and digestive efficiency. Horses in sustained heavy work, though increasingly rare in modern times, require increased energy provision while maintaining careful monitoring preventing weight gain when workload decreases. Any significant dietary changes should occur gradually over 7-10 days, allowing digestive microbiomes to adjust and preventing colic or other digestive upsets common when feed changes occur too rapidly.
