Assessment of Rectal Temperature using Infrared Thermal Camera in Pigs

Received Date:12 February 2022, Accepted Date:01 September 2022, Published Date:18 October 2022


Objective: To develop substitute measures for assessing accurate Rectal Temperature with an Infrared Thermal Imaging Camera in pigs. Methods: In the experiment, three different genetic groups were used: Hampshire, crossbred (Hampshire X Niang-Megha) and Niang-Megha. Apparently healthy 90 adult pigs (1-3 years) consisting 30 numbers from different group were used for each season; namely, summer (July) and winter (December). Thermal images were taken at different anatomical body sites. Appropriate anatomical sites were selected based on close association with rectal temperature (Trectal ). Developed a constant correction factors (CF) as a substitute measures using selected sites and validated for assessing accurate Trectal . Findings: Base of the Ear Temperature (Tear) and Eye Temperature (Teye) were highly correlated with Trectal . The correction factor was developed as substitute measures for assessing rectal temperature using base of the ear and eye temperature. Accordingly, the rectal temperature was recorded ranging from 36.45 to 38.25◦C with Tear and 35 to 38.2◦C with Teye based on the developed correction factor. Novelty: Developed correction factors as a substitute measures for accurate assessment of rectal temperature by non-invasive techniques by measuring base of the ear and eye temperature with an infrared thermal imaging camera.
