Evaluation of Rumination Behavior in Cows Before and After Surgical Correction of Left Displaced Abomasum

The aim of this study was to investigate the rumination behavior of cattle in the diagnosis of left displaced abomasum (LDA) and in the surgical correction process. In 6 cows diagnosed with LDA, surgical abomasopexy was performed via left-flank laparotomy. The cow monitoring system attached to the neck of each animal was used to monitor the rumination times. Rumination data were evaluated over a 35-day period covering the healthy period, diagnosis and treatment of LDA. In the healthy period (control group), the mean rumination time of the animals was determined as 508.74±8.52 mins. In the preoperative period, the mean rumination time was determined as 335.57±16.29 mins (-14 and -8 days) and 234.48±13.83 mins (-7 and -1 days) and a statistically significant decrease was determined compared to the healthy period (p
