The study was carried out to compare the electrocardiographic outline of young and adult crossbred Jersey cows of Odisha. ECG was taken in all the animals in standing position. The lead I 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 and duration of P-wave was concerned, the young animals recorded non-significantly higher values than adults. The same trend was observed for QRS complex amplitude and duration of T wave. The duration of QRS complex and amplitude of T wave recorded almost similar values in young and adults without any significant difference. The amplitude of QRS complex measured between 0.4 mV and 1.5 mV in young animals with a QS configuration (below the baseline) in 5 out of 6 animals. All QRS complexes and majority of T waves in lead I 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. With respect to Q-T interval, the young animals and adults revealed no significant difference between each other with higher values recorded in adults. R-R interval was significantly lower in young animals. The heart rate in young animals was found to be significantly higher than adults. The study establishes normal reference values of different ECG parameters.
