Extraction of interaction information between breeding cows with GPS and its application to estrus detection

This study focuses on bovine sociality and proposes a new method of detecting estrus through the detection and the analysis of interactions between cows. In the proposed method, we mainly trace bovine behavior when an animal approaches other cows based on their time-series location data measured by a GPS installed on each animal. The cow's estrus is detected by analyzing the interaction information extracted from the behavior. Our proposed method experimentally obtained more accurate results than the existing method of estrus detection.
