To determine the responsiveness of the pituitary–gonadal axis of peri-pubertal colts to GnRH, buserelin (0.5, 1, 5, 10 and 40 μg) was given to 13 male Thoroughbred yearlings (n=3–8 colts per dose).

Water and electrolyte supplementation is crucial for the prevention of dehydration and associated complications during endurance races.

To determine daily variation in urinary clearance and fractional excretion (FE) of electrolytes and minerals within and between horses and to compare volumetric and single-sample urine collection for determining FE values of diets with a range of dietary cation-anion balance (DCAB).

To determine the effect of dietary starch, bicarbonate, and fat content on metabolic responses and serum creatine kinase (CK) activity in exercising Thoroughbreds with recurrent exertional rhabdomyolysis (RER), 5 RER horses were fed 3 isocaloric diets (28.8 Mcal/d [120.5 MJ/d]) for 3 weeks in a crossover design and exercised for 30 minutes on a treadmill 5 days/wk.

The nature of vitamins is as varied as any group of nutrients. In general, vitamins are organic compounds required in minute amounts that cannot be produced in adequate quantities in the body and must be obtained from food or the environment.

The endurance horse is unique among all other equine athletes. Because of the prolonged demands placed upon the endurance horse with protracted moderate intensity exertion, its performance may be influenced quickly by the quality of its diet.
