This research was established to assess the precision of the infrared (IR) camera and thermometer in measuring different body regions of sheep. This study was undertaken in the animal farm at the College of Agricultural Engineering Sciences, University of Duhok, Kurdistan Region of Iraq. The temperature was measured from the rectum using a digital thermometer. At the same time, the peripheral temperatures were measured from the ears, muzzle (MUZ), inner thigh (IT), inguinal region (ING), rectum, vulva, and five areas of the eyes, including nasal conjunctiva (NC), nasal limbus (NL), center cornea (CC), temporal limbus (TL), and temporal conjunctiva (TC) using IR thermometer and IR camera. The temperatures obtained from the IR thermometer were higher than those obtained from the digital thermometer. only NC temperature was found to be significantly (P<0.05) higher than other eye regions, and rectal and vulva temperatures. IR thermal camera showed no significant differences in the eyes' NL, CC, TL, and TC regions compared to rectum and vulva temperatures using the digital thermometer. The muzzle temperature was significantly (P<0.05) lower than all other body parts. In addition, the inner thigh, inguinal region, and ear temperatures were significantly (P<0.05) higher than rectum and vulva temperatures. The rectum and vulva temperatures obtained from the IR thermometer were significantly higher (P<0.05) than thermal camera and digital thermometer temperatures. In conclusion, thermal cameras as a non-invasive and accurate method can be an alternative temperature measuring method.
