[Experimental studies of anemia in cattle caused by immune antibody. 2. Behavior of plasma hemoglobin, and serum bilirubin, inorganic phosphorus and calcium].

The course of haemolytic anaemia, caused by immune antibody, was characterised in greater detail with reference to eight heads of young cattle examined for plasma haemoglobin, bilirubin, inorganic phosphorus, and calcium in serum. Inorganic serum phosphorous values were found to decline strongly immediately after the onset of iso-immune serum transmission. Severe haemolysis developed, but only moderate haemoglobinaemia and no haemoglobinuria at all occurred. Bilirubin was increased over a long time, which seemed to support the assumption of gradual erythrocyte decomposition. The usefulness of inorganic serum phosphorus determination as an approach in support of early diagnosis of aggravating haemolysis is confirmed and recommended for metabolic monitoring of cattle herds.
