Popis: A study was conducted to determine the viability of ear tag deployed accelerometers to infer behaviours related to grazing and pasture height in sheep. Nine ryegrass/white clover pasture plots were mown to three different heights: “Low” (2.5 cm), “Medium” (5 cm) and “High” (10 cm). Sheep were allocated to one of three groups with each group grazing each height treatment for 36 hours over one week. Accelerometer signals were annotated against video recordings. Behaviours isolated from video analysis included: standing, walking, ruminating and grazing. Head up and head down posture was successfully inferred from the accelerometer signals by monitoring the raw Y- and Z-axes. Sheep grazing the “High” treatment tended to graze more consistently than sheep grazing the “Low” treatment which grazed sporadically as they had to search for food. Based on movement intensity (signal vector magnitude), differences (P
