Twenty-five Thoroughbred (TB) and 25 Standardbred (SB) stables were visited to determine their feeding practices. There was considerable variation in diet composition and nutrient intake between stables. The TB trainers fed 11.0 plus-minus 2.4 kg and SB trainers 11.8 plus-minus 2.5 kg per day. The concentrate component of the diet weighed 7.8 plus-minus 1.6 and 7.7 plus-minus 2.3 kg for TB and SB stables, respectively, and the roughage component for TB horses 3.3 plus-minus 1.4 and SB horses 4.1 plus-minus 1.4 kg per day. The digestible energy intake of horses at TB stables was 129 plus-minus 29 MJ per day and at TB stables 132 plus-minus 31 MJ per day. Crude protein intake of TB horses was 1452 plus-minus 363 g and SB horses 1442 plus-minus 338 g per day. Although many trainers used vitamin and mineral supplements, this appeared unnecessary in many instances, especially with respect to Fe. Ca and NaCl supplementation was necessary for some diets. While there was a wide range in feed intake and diet composition for both TB and SB horses, average nutrient intakes were similar to National Research Council (1989) recommendations for horses performing intense work.
