Figure 5From: Evaluation of eating and rumination behaviour using a noseband pressure sensor in cows during the peripartum periodNumber of chewing cycles per regurgitated cud. Number of chewing cycles per regurgitated cud in 10 cows (group B) from 10 days before to 10 days after parturition (medians, minimum, maximum). The yellow area indicates the reference interval (53 to 57 chewing cycles) calculated as the 90% confidence interval of the median of the recordings in 10 control cows (group A). */** compared with day 0 (parturition): P < 0.05/P < 0.01 (Bonferroni test).Back to article page
