Ad libitum intake of hydroelectrolytes and energy replenishers in horses submitted to marcha training

Abstract

This study aimed to measure the ad libitum intake of hydroelectrolytes and energy replenishers containing different concentrations of sucrose, dextrose, and maltodextrin in six Mangalarga Marchador horses subjected to gait training. The animals were distributed between three treatments in a 6x3 crossover design (six animals/three treatments). After exercising, the animals were sent to individual stalls where they received their respective treatments: Water (control), hydroelectrolytes and energy replenishers 1 (HES1), or hydroelectrolytes and energy replenishers 2 (HES2). The volume ingested and the animal's serum levels of sodium, potassium, chloride, ionized calcium, magnesium, and phosphorus were measured. Data were collected at the following times: T0, just before exercising; T1, immediately after exercising; T2, 2 h after exercising; T4, 4 h after exercising; and T6, 6 h after exercising. The ingested volumes of HES1 and HES2 were similar to those of the control group, demonstrating good palatability. In addition, no adverse effects were detected.
