Abstract
1. A radio-telemetric system linked to a thermistor- probe embedded in deep muscular tissue has been used to record continuously variations in deep•body temperature during 46-66 hr. in three Hereford (temperate) and three East Mrican zebu (tropical) cows under similar temperate field conditions. 2. The limitations of the 'probe' technique for measuring deep-body temperature are discussed. 3. The results indicate that under moderate climatic conditions there is little difference in the temporal patterns of deep-body temperature of the two breeds of cattle. In both Hereford and zebu cows there was a monophasic nychthemeral variation in deep-body temperature of between 1 and 20 C. about a mean close to 38.40 C.
