The effect of feeding frequency and voluntary sodium intake (VSI) on fluid shifts plasma aldosterone concentration (PAC) were studied at rest after exercise in six athletic horses. horses fed twice a day (2TD) times (6TD) for 25 days each protocol, according to changeover design. VSI was measured by weighing horse’s salt block daily. Feeding 2TD or 6TD caused no major alterations shifts, but the treatment there postprandial increase protein osmolality that lasted <1 h. PAC not affected frequency. ranged from 0 62 mg ⋅ kg body weight −1 significant PAC. At <26 , diurnal rhythm noted. Water intake, fecal concentrations potassium, packed cell volume during influenced VSI. response did differ between treatments. In conclusion, VSI, frequency, has effects electrolyte regulation
