This study aims to assess the correlation between surface temperature estimated by infrared thermography and core temperature measured with rectal thermometer in weaning and fattening pigs. A total of 108 pigs were used in this study. Thermal images of the eye of each animal were recorded with a thermal imaging camera, rectal temperatures were measured using a calibrated digital thermometer. The average rectal temperature was 38.9 ± 0.4 °C (MIN = 37.9 °C; MAX = 40.1 °C) and the average eye temperature was 36.7 ± 0.1 °C (MIN = 34.8 °C; MAX = 38.8 °C). Our results showed that the mean eye temperature estimated by infrared thermography was significantly correlated (r = .581, P < .01) with rectal temperature. The correlation was significant and strong for weaners (r = .739, P < .01), significant although weak for fatteners (r = .236 P < .05). Thermography could be a valid method to estimate the core temperature of pigs under farm condition.
本研究旨在评估在断奶和育肥猪中，通过红外线热成像估计的表面温度与直肠温度计测量的核心温度之间的相关性。本研究共使用了 108 头猪。使用热成像摄像机记录了每只动物眼睛的热图像，使用经过校准的数字温度计测量了直肠温度。平均直肠温度为 38.9 ± 0.4°C（MIN = 37.9°C；MAX = 40.1°C），平均眼部温度为 36.7 ± 0.1°C（MIN = 34.8°C；MAX = 38.8°C）。我们的结果表明，通过红外线热成像估计的平均眼部温度与直肠温度显著相关（r =.581，P <.01）。对于断奶猪，相关性显著且较强（r =.739，P <.01），对于育肥猪，相关性虽然较弱但显著（r =.236，P <.05）。热成像可以成为一种在农场条件下估计猪核心温度的有效方法。
