Selected clinical and biochemical variables were studied in 2 groups of severely dehydrated, diarrhoeic calves before and after fluid therapy. Samples of faeces for microbiological examination were taken before intravenous (IV) rehydration. Solutions used for IV rehydration contained salts of NaCl, NaHCO3, KCl and glucose in different quantities for calves in Groups 1 and 2. Before IV rehydration diarrhoeic calves in Group 2 presented mean blood values of pH 7.12, base excess (BE)-14.72 mmol/l standard bicarbonate (SB) 9.86 mmol/l which were significantly lower (P0.05) than in calves in Group 1 before IV rehydration. The metabolic acidosis together with hyperkalemia, prerenal uremia and haemoconcentration were restored after fluid therapy. Rehydration was successful in 79.0% of all diarrhoeic calves.
