Evaluation of infrared thermography findings in pseudopregnant rabbit

Öz

The effectiveness of infrared thermography (IRT) in the diagnosis of pseudopregnant rabbits, the change of these images in the pseudopregnancy process, and its relationship with serum progesterone (P4) level was investigated. 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 0th 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 valueswere measured by Enzyme-linked immunosorbent assay (ELISA) method. In the pseudopregnant group, the temperatures of the eyes, nose, and vulva were higher on the 10th 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 15th 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 low negative correlation (-0.04) was observed between serum P4 value and IRT and rectal measurements, and the highest correlation was observed between nasal temperature and rectal temperature (0.28). Infrared thermography applications in rabbits are useful in non-invasive and rapid body temperature monitoring and can determine the temperature increase in the eyes, nose, and vulva on the 10th day of pseudopregnancy.
