Background And Aim: The mortality rate of perinatal calves is high, particularly in dystocia cases. Besides detectable conditions such as trauma or amniotic fluid aspiration, the potential salience of cardiological diseases in neonatal bovine deaths has received little attention. This study aimed to compare the electrocardiographic parameters of calves born under conditions of dystocia and eutocia.

Materials And Methods: Electrocardiographic, clinical, and laboratory diagnostic examinations were performed during the first 5 days of life on 40 calves. Of them, 20 calves were born under conditions of dystocia and 20 of eutocia.

Results: Electrocardiograms (ECGs) did not show detectable arrhythmias in all calves. Both groups exhibited tachycardia on their first ECGs. The QT and ST interval durations developed differently over time in both groups, suggesting that these may be related to conditions of birth.

Conclusion: The electrocardiographic differences between calves born of dystocia and eutocia could be a factor in the increased mortality rate of calves born of dystocia.
