Descripción:	Abstract: Detecting and monitoring pregnancy in cattle is essential and can be achieved through various methods. In recent years, new technologies have been explored to better understand reproductive phenomena, with particular attention given to non-invasive approaches. This study reports thermographic and clinical findings of two Zebu cows (Cow 1: spontaneous abortion; and Cow 2: pregnant) at 236 days of gestation. Eight hours after abortion, thermal imaging and rectal temperature were recorded (First Trial) and compared with the pregnant cow, kept under the same housing and dietary conditions. A second evaluation was conducted five days later (Second Trial). No clinical abnormalities or fever were observed in either cow. In both trials, the pregnant cow consistently showed a 0.9°C higher average abdominal temperature compared with the cow that experienced spontaneous abortion. This difference may be related to increased blood flow and metabolic activity in the uterus during gestation, resulting in greater heat conduction to the body surface. Despite the short interval post-abortion, thermography detected temperature differences suggestive of reproductive status. These findings support the potential of infrared thermography as a non-invasive tool for assessing reproductive status and thermal physiology in cattle.
