dc.description.abstract | Four experiments were conducted to determine a management strategy for providing effective electrolyte concentrations in the drinking water of newly weaned piglets to encourage early fluid and feed intake [weaning age=19±1 d, n=360]. In Exp. 1, electrolytes (Vetoquinol, QC, Canada) were provided at the label dose of 60 ml/L of water for 0, 6, 12, 18 or 24 h on d1-d3. In Exp. 2, electrolytes were given ad lib at 100, 75, 50, 25 or 12.5 % of the label dose on d1-d3 (72 h). In Exp. 3, electrolytes, at the label dose, or water (control) were given ad lib on d1, d1 and d2, d1-d3, or d1 and d3. In Exp. 4, based on the results of the previous experiments, the most effective combinations of "hours/concentration/days"(12 h of 25 % or 50 % on d1 or alternate days) were tested. All piglets had water ad lib from d4-d14. In Exp. 1, higher feed disappearance was observed in the 0, 6 and 12 h/d than 18 h/d and 24 h/d electrolyte groups (P<0.05). In Exp. 2, by d14 piglets in the 12.5, 50, 75, and 100 % groups experienced lower weight gain and daily FI than those in the 25 % group (P<0.05). In Exp. 3, piglets that received electrolytes on d1 only had comparable FI to those in the water group (respectively; 64.55 g/pig/day vs. 75.59 g/pig/day; SEM=8.61). Overall, evidence indicated that weanlings tended to benefit from electrolyte administration at 25 % of the label dose and durational period of ≤ 12 h/d. However, in Exp. 4 testing neither 25 % or 50 % concentration for 12 h/d result in improved daily FI despite the increased FLI in groups given electrolytes on alternate days. The results suggest that high electrolyte intake occurred at the expense of feed intake. | en |
