Question: what is the average body temperature of a cow?
Answer: The rectal temperature reference range for an adult cow is 37.8-39.2°Celsius [100.0-102.5°Fahrenheit], and a little higher for a calf at 38.6-39.4°Celsius [101.5-103.5°Fahrenheit]. However, bear in mind that a small proportion of 'normal' animals will have a rectal temperature outside of these ranges.
