Frontiers in Bioscience-Landmark (FBL) is published by IMR Press from Volume 26 Issue 5 (2021). Previous articles were published by another publisher on a subscription basis, and they are hosted by IMR Press on imrpress.com as a courtesy and upon agreement with Frontiers in Bioscience.
This article reviews the literature on the circadian and estrous rhythms of body temperature in farm animals. Although most research in this area has lacked the methodological sophistication of research conducted on laboratory animals, the experimental results are consistent with the general principles of thermal chronobiology derived from laboratory studies and, at the same time, provide specific information about the peculiarities of livestock species. Detailed knowledge of the normal parameters of the body temperature rhythms is important for the advancement of diagnostic procedures in veterinary medicine and for the optimization of farm yield in the dairy and meat industry.
