(a) Lying bouts per day relative to parturition. Mean number of lying bouts one week before calving in 16 cows (mean ± SE). All days were compared to day-6 as a baseline. On the day before calving cows had a greater number of lying bouts compared to day-6; * indicates p < 0.05; (b) Lying bouts per hour relative to parturition. Mean hourly lying bouts 6 h before calving in six cows (mean ± SE). There were no differences in lying bouts between the baseline (−6 h) and the hours leading up to parturition.
