The sensor-based system consists of a three-dimensional accelerometer, working as a pedometer, which automatically analyzes various motions, amongst others the lying bouts, walking times and motions like getting up or lying down. RumiWatch also includes a noseband sensor which shows the time of food and drink intake as well as rumination periods. By visualizing the walking and eating behavior of the cows being close to parturition, we aim at predicting the phases of parturition. As a long-term objective, farm staff will have the possibility to notice in real time via on-line monitoring of the data, when a cow is about to give birth and can thereby assist early enough to avoid potential dystocia and reduce calf mortality. The research will take place on a farm in Niederpöllnitz, Thuringia, Germany, which houses around 1000 milking cows in free-stall barns. Pregnant cows are being moved to separate calving barns three days ante partum. For this project, approximately 150-200 cows will wear the RumiWatch system over a period of 14 days during the late transition phase until 2-3 days after parturition. Afterwards, the data will be checked, analyzed and typical patterns around birth described. We will then compare the data to video camera recordings of the parturitions and try to link patterns in the behavior ante partum for the prediction of the different phases of parturition. Once these patterns are standardized, further research could identify aberrances in the behavior for prediction of dystocia or potential metabolic disorders such as hypocalcemia.
