Abstract: Highlights•Smart collar for monitoring the cattle daily behavior.•Data from two intensive farms have been recorded.•Collars monitor five activities and the steps number.•Unsupervised anomaly detection techniques were implemented for the estrus event detection.•Two different model topologies were evaluated.•For the individual performance, the results are 100% in some cows.
