Progress on Infrared Imaging Technology in Animal Production: A Review

Abstract

Infrared thermography (IRT) imaging technology, as a convenient, efficient, and contactless temperature measurement technology, has been widely applied to animal production. In this review, we systematically summarized the principles and influencing parameters of IRT imaging technology. In addition, we also summed up recent advances of IRT imaging technology in monitoring the temperature of animal surfaces and core anatomical areas, diagnosing early disease and inflammation, monitoring animal stress levels, identifying estrus and ovulation, and diagnosing pregnancy and animal welfare. Finally, we made prospective forecast for future research directions, offering more theoretical references for related research in this field.

Evaluation of Usefulness of Infrared Thermography for the Detection of Mastitis Based on Teat Skin Surface Temperatures in Dairy Cows

“…Infrared thermography (IRT) can detect infrared radiation emitted from an object, which is a measure of its surface temperature (ST) and can present it as a heat map (Travain et al 2015;Radigonda et al 2017;Harrap et al 2018;Menegassi et al 2018;Qu et al 2020;Isola et al 2020;Schmitt and O′Driscoll 2021;Zheng et al 2022). However, an individual's average body temperature may vary slightly when IRT is used to measure temperature.…”
