Behavioral changes to detect estrus using ear-sensor accelerometer compared to in-line milk progesterone in a commercial dairy herd
The first objective of this study was to compare behavioral and ear temperature changes using accelerometer ear tags (CowManager system; Sensor) during the declining progesterone (P4) phase (expected estrus) and the luteal phase determined using in-line milk P4 analysis (Herd Navigator system; HNS)....
