Classification of ingestive-related cow behaviours using RumiWatch halter and neck-mounted accelerometers

•Simple decision-tree (DT) algorithm to classify feeding and ruminating behaviours.•The DT performs similar to support vector machine and a RumiWatch noseband.•The use of a simple DT would help implementing the algorithm on the on-cow sensor.•It would enable online measurements of the ingestive-related cow behaviours.
