The normal body temperature of goats is usually reported in the range of 101.5 to 103.5 F. Goats of lighter body weight are more likely to have higher temperatures than larger one when exposed to sun. To accurately assess the state of the goat, it is useful to record body temperatures in apparently normal herd mates of the same size. The temperature is taken with a rectal thermometer for 3 minutes.
When taking a rectal temperature, be sure to lubricate the thermometer with petroleum jelly or even saliva before inserting in the anus. Before inserting a thermometer, it is a good practice to tie a string through the loop at the end of the thermometer and attach a clip. You can use the clip to attach the thermometer to the hair or wool on the animal. This will prevent you from loosing the thermometer in the pen.
