Abstract

The most common causes of death in diarrheic calves are dehydration and acidosis. Treatment of diarrhea
in calves is primarily based on correcting the electrolyte, acid-base imbalances, fluid and energy deficits
via using of oral and parenteral solutions. Just an oral rehydration therapy is the most effective therapy for
mildly or moderately affected diarrheic calves. The best way of treating calves with severe dehydration
and acidosis is use of intravenous fluids. Isotonic crystalloids are widely used to treat dehydrated calves
with diarrhea. This solutions should be considered to the replacement of interstitial fluid volume. Sodium
bicarbonate should be used to in calves with severe metabolic acidosis. Hypertonic crystaloid solutions
(e.g., %7.2 hypertonic saline, 4ml/kg, i.v.) are valuable in the initial treatment of endotoxemic calves with
diarrhea because of their rapid resuscitative effects. The effects of hypertonic crystaloid solutions can be
prolonged by adding colloid solutions (Dextran 70). Administration of colloid solutions causes an increase
in plasma volume, which increases the plasma oncotic pressure. Absorption of orally administered fluids
can be enhanced by intravenous administration of hypertonic saline-dextran solution. Antibacterials
should not be used in calf diarrhea unless indicated. Probiotic and oligosaccharides should be used in calf
diarrhea.
