Effects of strangulated ileal obstruction on clinico-hematological, acid-base, blood gases and biochemical status in crossbred cow calves (Bos indicus)

The effects of strangulated ileal obstruction were evaluated in six male cow calves. The animals showed signs of weakness, dehydration and shock at terminal stages. The survival time ranged from 9–13 days. BUN values increased significantly at last stages. Sodium and potassium values in the blood showed insignificant declining trend, whereas plasma chloride values dropped significantly at terminal stage. Blood glucose and lactate values were elevated at the end stage. Changes in biochemical constituents of saliva were almost parallel to those of plasma. Significant increase in arterial pH, HCO₃⁻ and base excess (ECF) indicated severe metabolic alkalosis. Significant fall in PaO₂ values pointed to arterial hypoxaemia.
