Productive lifespan and resilience rank can be predicted from on-farm first parity sensor time series but not using a common equation across farms

This study shows that sensor data from first lactation can predict dairy cows' lifetime resilience rankings within farms, but a common model across farms is not feasible.

Validation of a novel milk progesterone-based tool to monitor luteolysis in dairy cows. Timing of the alerts and robustness against missing values

This paper validates two algorithms for detecting luteolysis in dairy cows using simulated milk progesterone data, finding that PMASC detects luteolysis earlier and is more robust to missing values than a Kalman filter approach.
