Effects of maximal exercise on the blood composition of the racing camel

Haematological and blood biochemical changes were studied in nine camels after maximal exercise over 4 or 5 km. There was a lack of splenic reserve for red blood cells, indicated by a minimal increase in haemoglobin concentration and haematocrit. There were marked increases in plasma lactate (to over 20 mmol/litre), plasma ammonia and plasma glucose and a pronounced decrease in circulating free fatty acids. There were small but significant increases in plasma calcium, magnesium, sodium, potassium, chloride and phosphate concentrations.
