Este estudo teve como objetivo medir ad libitum intake of hydroelectrolytes and energetics replacers in horses submitted to “marcha” training. Six horses Mangalarga Marchador were used in “marcha” training. The animals were distributed in three treatments in crossover 6x3 system (six animals / three treatments). After exercise the animals were sent to individual stalls where they received their treatments: Water (control); Hydroelectrolytics and Energetics Replacers 1 (HER1) and Hydroelectrolytics and Energetics Replacers 2 (HER2). Were measured the volume ingested, sodium, potassium, chloride, ionized calcium, magnesium and serum phosphorus. The evaluations were performed at the following times: T0: just before the start the exercise; T1: immediately after the end of the exercise; T2: two hours after the exercise; T4: four hours after the exercise and T6: six hours after the exercise. It is conclude that the ingested volume of RHE1 and RHE2 was similar to control group, demonstrating expressive palatability, besides not causing the appearance of adverse effects.
