To evaluate the effectiveness of thermal infrared scanning as a technique to detect estrus, 27 Holstein-Friesian cows were observed for a 90-d period beginning in the second week postpartum. The area enclosed by the 37-C isotherm on the gluteal region of a cow's body tended to increase in association with the occurrence of estrus. This increase became… CONTINUE READING
