(a) Lying time per day relative to parturition. Changes in average lying time in minutes one week before calving in 16 cows. All days were compared to day-6 as a baseline (mean ± SE). * indicates p < 0.01. On the days of and before calving cows spent less time lying down compared to d-6. * indicates p < 0.05; (b) Proportion of time spent lying per hour relative to parturition. Mean hourly lying time 6 h before calving in six cows (mean ± SE). All hour intervals were compared to 6 h prior to calving as a baseline. In the hour before calving (hour −1), cows spent less time lying than 6 h prior to calving (p = 0.0360). * indicates p < 0.05.
