The present study evaluated the potential of the infrared thermography technique for estrus detection in Surti does. Based on the presence of estrus-specific behaviour, physiological signs as well as higher LH, FSH, estrogen and lower progesterone hormone concentration, 24 Surti does were divided into two groups, viz. estrus and non- estrus does. Recording of surface temperatures, rectal and tympanic temperatures was done using an Infrared thermal camera (FLIR T420), digital thermometer and infrared non-contact tympanic thermometer, respectively. It was concluded that temperatures of the vulva, rectal surface, rectal and tympanic temperatures are significantly higher in estrus does. Further, a strong, significant positive correlation was observed between vulvar and pudendal, rectal surface temperatures, rectal temperature as well as tympanic temperature. Thus, it may be concluded that the infrared thermography technique holds the potential for detecting estrus in Surti does.
