Data Sheet 1_Activity-based first estrus detection in grazing heifers and first-lactation dairy cows for use as novel fertility phenotypes at scale.pdf<p>Timing of first detected estrus of peripubertal heifers and postpartum dairy cows is an informative predictor of reproductive performance with potential to support genetic gain in fertility. Current methods of assessing reproductive status can be time consuming (e.g., requiring repeated manual observation), expensive (e.g., where laboratory analysis is required) or lack temporal resolution (e.g
