A system (20) for measuring relative front (12, 13) and hind leg (16, 17) positions of a standing ungulate. The system includes a sensing area within which an ungulate, to be measured, stands. The sensing area comprises a plurality of discrete linear sensor regions (30) spaced a known distance apart. Each sensing region having a sensor operatively associated therewith, the sensor is responsive to the presence of the lower part of a leg within a sensing region. The system further includes a processor for receiving data from each sensor. The processor identifies those sensor regions within which a lower part of a leg is present and, based upon the distance between the identified sensor regions, determines the relative front and hind leg positions.
