Recording Intrareticular Temperatures by Radiosonde Equipment

Department of Dairy Husbandry, Agricultural Experiment Station, Brookings, South Dakota

ABSTRACT

Periodically, physiological temperatures of animals have been recorded. The majority of these recordings have been with clinical thermometers. Some have been recorded with thermocouple types of devices. All of the recordings have been of short duration and have excited the animals being observed.

The transmitter used in these experiments was small enough to pass through the esophagus with a stomach tube into the rumen of a sheep. The cylindrical unit was 13/16 of an inch in diameter and the length approximately 3 in. One end of the unit was weighted so it was heavy enough to keep the instrument oriented in an upright position. This weight also allowed the instrument to sink to the bottom of the rumen and subsequently find its way into the reticulum, where it remained throughout the experiment. X-ray and laporatomy determinations have shown that the temperature recordings were transmitted from the base of the reticulum.
