Zusammenfassung:The study was carried out to compare the electrocardiographic outline of young and adult crossbred cows of Odisha and to establish normal reference values of different ECG parameters. ECG was taken in all the animals in standing position. The lead II electrocardiogram was analyzed and data was compared using student’s t-test. The P wave had a positive configuration in both young and adult animals. As far as the amplitude of P-wave was concerned, the young animals recorded significantly higher values than adults. The same trend was observed for QRS complex amplitude. The duration of QRS complex recorded almost similar values in young and adults without any significant difference. All QRS complexes and majority of T waves in lead II of adult animals presented a negative configuration. However, the T wave in most of the young animals had a positive configuration. The P-R interval was significantly lower in young animals than adults indicating faster atrioventricular conduction time in young animals. With respect to Q-T interval, the young animals and adults revealed no significant difference between each other with higher values recorded in adults. However, the R-R interval was significantly lower in young animals. The heart rate in young animals was found to be significantly higher than adults. The results of the study can be used as a standard during evaluation of cardiac status of crossbred cows.
