Summary and Implications
The objective of this study was tocreatea pictorial lying down-standing up sequence depiction in multiparous sows.Eighty-five multiparous sows were moved from their home stallto a testingstall where they were video recorded for one lying down–standing up event on 30, 60 and 90 days of gestation. The digital video camera was positioned on the adjacent stall so the sows’ profile was visible while recording. Observations ceased when the sow successfully lied down or if 2.5 hours elapsed since recording began. Normal standing and lying pictorial depictions were created, and deviations fromthenormal lying down and standing up sequences were also pictorially depicted. This is the first published pictorial depictions on mulitparous sows on the standing-lying-standing sequence.
