Circadian and seasonal variation of the body temperature of sheep in a tropical environment

Int J Biometeorol. 1995 Nov;39(2):69-73. doi: 10.1007/BF01212583.


Nychthemeral and annual rhythms of the rectal temperature were determined for Corriedale sheep in a tropical climate. The minimum rectal temperature averaged 39.55 degrees C at 0500 hours in summer, and 38.87 degrees C at 0600 hours in winter. The maximum was 40.03 degrees C in summer (1700 hours) and 39.33 degrees C in winter (1830 hours). Annual cycle of the rectal temperature showed a minimum in July and maximum in December.
