Feeding Andalusians in intensive haute école training requires sophisticated nutritional programs balancing high energy demands of athletic work with needs for maintaining optimal weight, supporting recovery, and preventing metabolic issues that could compromise performance. These horses work at extremely high intensities, utilizing maximum power and collection for sustained periods, creating energy requirements substantially exceeding those of horses in moderate work. Forage remains the dietary foundation, with adult horses consuming approximately 1.5-2% of body weight daily in quality hay, but concentrated feeds become much more important for horses at this performance level.
Concentrate selection should prioritize feeds formulated for performance horses, providing balanced nutrition supporting intense athletic effort. Protein requirements increase to approximately 12-14% of the diet, supporting muscle development, maintenance, and repair after strenuous work. Fat inclusion at 6-10% of the diet provides additional calories without the metabolic stress of excessive carbohydrates, supporting sustained energy for long training sessions while maintaining digestive health. Many programs utilize commercial performance feeds designed specifically for dressage or high-level sport horses, ensuring appropriate nutrient profiles.
Feeding frequency affects both digestion and performance. Dividing concentrates into 3-4 daily meals reduces metabolic stress while maintaining steady energy availability. Small, frequent meals better match equine digestive physiology than large meals, reducing colic risk while ensuring consistent nutrient absorption. Timing meals relative to work matters significantly - avoid working horses within 2-3 hours of large grain meals, as digestion diverts blood flow from muscles and increases colic risk. Post-work feeding supports recovery, with meals offered 30-60 minutes after horses cool completely.
Electrolyte supplementation becomes essential for horses working intensively, particularly during warm weather when sweating rates increase dramatically. Classical training's intense collection work generates significant metabolic heat despite sometimes appearing less strenuous than activities like jumping or racing. Many programs provide electrolytes daily during heavy training periods, either through feed additives or separate supplements. Ensuring adequate water consumption when supplementing electrolytes is critical, as increased mineral intake without sufficient hydration can cause problems.
Protein quality affects muscle development and recovery. Select feeds with protein from high-quality sources including soybean meal, alfalfa, or other digestible protein sources providing appropriate amino acid profiles for muscle synthesis and repair. Some programs supplement with specific amino acids including lysine, particularly for horses building fitness or those showing inadequate muscle development despite apparently adequate overall protein intake.
Supplements commonly used for haute école horses target joint health, muscle function, and overall soundness. Glucosamine and chondroitin supplements support joint health under the stress of intense collection. Omega-3 fatty acids may help manage inflammation from intense training. Vitamin E, particularly natural-source (d-alpha tocopherol), supports muscle function and recovery. Magnesium supplementation may benefit some horses, supporting muscle function and potentially helping horses remain focused and relaxed during training. However, supplement programs should be developed with veterinary guidance, as over-supplementation can cause problems while targeted supplementation addresses specific needs.
Weight management requires constant vigilance, as haute école horses must maintain lean, muscular condition without excess fat that could compromise athletic performance or add unnecessary weight affecting movement quality. Regular body condition scoring every 2-4 weeks allows early detection of unwanted weight gain or loss. These horses should carry sufficient flesh for energy reserves and cushioning without excess, typically maintaining body condition scores of 5-6 on the 9-point scale. Their intensive work generally prevents obesity if feeding programs match energy expenditure.
Hydration is critically important for athletic horses, with requirements potentially exceeding 20 gallons daily during intensive training or warm weather. Provide constant access to clean, fresh water, checking multiple times daily to ensure adequate consumption. Some horses benefit from electrolyte-supplemented water encouraging consumption, though always provide plain water simultaneously allowing horses to choose based on their needs. Monitor water intake carefully, as decreased consumption can signal developing health issues.
Seasonal adjustments account for training intensity variations and weather impacts. Winter feeding may increase to support thermoregulation in cold climates, particularly for horses in year-round training. Summer feeding might adjust for heat stress affecting appetite and metabolism. Competition or demonstration seasons often see temporary feed increases supporting peak training intensity, while relative rest periods allow gradual reductions. The key is matching energy intake to expenditure while maintaining optimal body condition and performance capacity.
Special dietary considerations for performance horses include managing gastric ulcer risk, common in horses under training stress. Many programs implement ulcer prevention strategies including frequent small meals, alfalfa inclusion in diets (its calcium may buffer stomach acid), free-choice hay, and potentially pharmaceutical prophylaxis for horses at high risk. Regular veterinary monitoring for ulcers allows early intervention if problems develop, preventing performance impacts and ensuring horse welfare during demanding training programs.
