Traditionally, the methods used to detect estrus in dairy cows include visual observation, tail painting, tail chalking, rump-based pressure and scratch-off patches. In high-producing cows, the duration and intensity of estrus behavior is considerably lower than that in dairy cows of a few decades ago. In fact, standing estrus only occurs in 30 to 80% of lactating dairy cows. For this reason, precision dairy monitoring devices (tag, leg, collar) that measure cow activity, rumination, and feeding and lying behaviors are commonly used for estrus detection.
