Figure 4From: Evaluation of eating and rumination behaviour using a noseband pressure sensor in cows during the peripartum periodNumber of regurgitated cuds. Number of regurgitated cuds in 10 cows (group B) from 10 days before to 10 days after parturition (medians, minimum, maximum). The yellow area indicates the reference interval (366 to 611 cuds) calculated as the mean ± 2 sd (488.1 ± 122.56 cuds) of the recordings in 10 control cows (group A). ** compared with day 0 (parturition): P < 0.01 (Bonferroni test).Back to article page
