Assay was conducted in completely randomized design in 3x3 Latin Square scheme repeated in time, with the treatments: 1 - Control (no supplementation), 2 - Mean dose (0.25g NaCl, + 0.125g KCl + 0.05g CaCl + 0.025gMgCl / kg BW), and 3 ? High Dose (0.625g NaCl + 0.3125g KCl + 0.125g CaCl + 0.0625gMgCl / kg of BW, equivalent 2.5 times the medium treatment). Three permanent cannulated horses in RDC horses were used. . Supplementation was given via nasogastric tube, four hours after the morning feeding. The basal diet maintained the ratio 70:30 (vol:con), with intake equivalent to 2% of BW. The animals received daily 116mg/kg of BW commercial mineral salt. The research was divided in two trials: I ? Electrolyte Balance: Was collected blood, urine, feces and digesta samples, for 12 hours after electrolyte supplementation to pH, electrical conductivity, [Na +], [K +], [ Cl-], [Ca2 +], [Mg2 +], buffering capacity, density, dry matter, and, protein and hematocrit in the blood plasma analysis. Was also evaluated water consumption, urine and feces production. Was release diet chemical analysis and feces and digesta chemical analysis. Trial II - Electrolyte Supplementation action on in vitro fermentation potential on RDC content: Was evaluated the gas production kinetics with semi-automatic technique, from RDC inoculum of horses collected 12 hours after electrolyte supplementation. Supplementation with electrolytes increased (P |
