What Is The Usual Temperature of an Adult Horse?
A horse’s normal body temperature can range between 37.2°C to 38.5°C (99.0°F to 101.4°F).
It is possible for a range of factors to affect your horse’s temperature, including humidity and hot weather and whether or not your horse has just been exercised. It is preferable to take a temperature reading at the same time every day, ideally first thing in the morning and/or last thing at night and to take it regularly to build up a picture of what is normal for each individual horse. Ensure that the thermometer is left in long enough to provide an accurate reading.
Newborn foals will have a slightly higher temperature (99.5° – 102.1°)
