Highlights • Data from a body-mounted accelerometer were used to classify posture and detect posture transitions in farrowing sows.• Comparative descriptors of lying behaviour can be extracted allowing further in-depth analysis.• The method may be used to predict the onset of farrowing and movements patterns potentially dangerous to piglets.
