“…The temperature of the external genital region rises dramatically during estrus, obviously due to genital congestion. This finding may be utilized to non-invasively diagnose estrus, which is crucial because this species lacks conventional estrous behavior (Polit et al, 2018).…”

T he sound health of livestock animals is essential for high productivity and good economic returns. The body temperature of farm animals is a very important parameter for ensuring their physiological health and well-being. For example, various physiological changes such as proestrus, estrus, pregnancy, breastfeeding, parturition, etc., can affect the body temperature (Neethirajan, 2017). The skin's surface works as a heat-radiating cooling

“…Although there is no hyperemia or cyanosis in the vulva, this temperature increase is expected to be in parallel with the measurements in the eyes and nose, but the limited literature on the subject creates difficulties in interpretation. Due to the excessive hairiness of the perineal region in vulvar measurements, the application is not practical, and this situation is similar to previous studies (Polit et al, 2018). When measuring in future studies, it should be kept in mind that the hairs in the area, the fecal residue found on the rectum's outer surface and cannot be cleaned entirely, can create artifacts and prevent temperature measurement.…”

“…An increase of more than 2.33 0 C was found in thermal images made due to hyperemia in the vulva in Chinchillas during the estrus period (Polit et al, 2018). Similarly, IRT can determine the vulvar temperature increase during estrus in rabbits and other livestock (Osawa et al, 2004;De Freitas et al, 2018;Façanha et al, 2018).…”

In the present study, the diagnostic efficiency of infrared thermography (IRT) implementation in pseudopregnant rabbits, the change of these images in the pseudopregnancy process, and its relationship with serum progesterone (P4) levels were examined. Fourteen healthy female rabbits of New Zealand breed were divided into two study groups. Pseudopregnancy induction was performed in the first study group with GnRH injection (0.2 ml Buserelin acetate, intramuscularly) on the 0 th day of the study (Group 1, n=7). The second group (Group 2, n=7) was given placebo (0.2 ml 0.9% NaCl, intramuscularly). Rectal temperature was taken from all rabbits on days 0-5-10 and 15; eye, nasal tip, and vulvar IRT were applied; and serum P4 values were measured by Enzyme-linked immunosorbent assay (ELISA) method. In the pseudopregnant group, the temperatures of the eyes, nose, and vulva were higher on the 10 th day (P<0.05). While time-dependent eye, nose, vulva, and rectal temperature changes were observed in the pseudopregnant group (P <0.05), it was not observed in the control group (P>0.05). The increase in rectal temperature was only on the 15 th day in the pseudopregnant group (P<0.001). Serum P4 value was high on day 0 in Group 1 (P<0.05), but no change was observed in both groups over time (P>0.05). A significant correlation was observed between the serum P4 value and rectal temperature and the groups (r=-0.32, P<0.05; r=0.35, P<0.01). A significant difference was determined between nasal temperature and rectal temperature (r=0.28, P<0.05). As a result, IRT implementation in rabbits; It was determined that it is useful in noninvasive and rapid monitoring of body temperature and can determine the temperature increase in the eyes, nose and vulva on the 10th day of pseudopregnancy.
