Abstract: A non-invasive technique that may be able to show variations in an animal's body temperature in reaction to a thermally demanding environment is infrared thermography (IR). The aim of the research was to assess the relationship between the rectal temperature of goats and surface temperatures estimated through non-invasive techniques, specifically utilizing an infrared thermometer and thermal imaging. Goats' summer rectal and surface temperatures of 39.18± 0.04 °C and 33.17± 0.26 °C, respectively, showed the impact of temperature changes on their ability to adjust body temperature. Pearson’s coefficient of correlation (r) was calculated for each surface temperature record in order to assess the relationship between the non-invasive surface temperature readings and the rectal temperature. Notably, the ocular globe temperature (PT) exhibited a positive correlation with a coefficient of 0.581 in relation to rectal temperature, at a significance level of p<0.05. Regression equation for predicting rectal temperature from surface temperature of ocular globe (PT), is Rectal temperature = 37.856 + 0.107 (PT). These results provide valuable insights into the relationship between surface and rectal temperatures in goats.
