Are Textbooks Wrong on Equine Body Temperature?

While books and other sources have stated “normal ranges” of temperatures for many years, there has been no recent published work examining whether these suggested normal values are representative of healthy horses. Enter Nottingham Trent University where researchers recently investigated the normal body temperature of horses in the Nottingham Trent University yard. The findings showed that the upper limit of the published ranges (38.5°C) is typically 0.5°C higher than the results from clinically normal horses in this study.
