Changes in Blood Chemistry, Body Weight and Haematocrit of Calves Affected With Neonatal Diarrhoea

SUMMARY The effects of diarrhoea were investigated in 60 experimental calves. It was found that diarrhoeic calves had significant losses in body weight and significant changes in the concentrations of plasma sodium, potassium and chloride and of blood urea. Changes in the haematocrit occurred infrequently. It was concluded that under the experimental conditions in which the calves were reared, diarrhoea caused isotonic and hypotonic dehydration.
