Abstract : Energy Metabolism of the chimpanzee was studied using simultaneously the techniques of direct and indirect calorimetry. The principal objective was to relate the magnitude and variability of the basal metabolic rate measured with the two techniques. Heat loss was measured with a thermoelectric, or gradient, partitional calorimeter; heat production was calculated from oxygen consumption measured with a Pauling meter and carbon dioxide production measured by infrared absorbtion. A total of 827 determinations were made on 14 chimpanzees, 7 males and 7 females. The animals were housed and measurements were made at an environmental temperature of 75 degrees Fahrenheit. All measurements were made in the morning between 8:00 and 12:00 o'clock noon; the subjects were awake, 15 to 18 hours postprandial, and confined to a relatively small cage. From each 40 minute test period a 10 minute low period was delineated to serve as an estimate of the basal metabolic rate. (Author)
