Description:	The aim of this study was to evaluate the performance of an Automated Activity Monitoring (AAM) system to detect estrus behavior in lactating Holstein x Gir (n=25, average 5/8 blood share) dairy cows under different management systems. Estrus detection was carried out by visual observation (VO), adhesive patches (AP), and AAM after a timed-AI (TAI) protocol. The VO and AP were considered as reference standards. The AAM system used was originally set up for barn-confined Holstein cows.
