Association of production diseases with motor activity-sensing devices and milk progesterone concentrations in dairy cows

We have previously established that the efficiency of identifying oestrus with activity-sensing devices can be compromised by common production diseases; the present study was undertaken to determine how these diseases may affect device readings. A total of 67 Holstein-Friesian cows,>20 days postpartum, were equipped with activity-sensing neck collars and pedometers, and simultaneous twice a week milk progesterone profiles were also monitored. The influences of common production stressors on maximum activity and progesterone values were analysed.
