Abstract

Objective: To evaluate the electrocardigraphic changes in the experimentally induced ascitis in BROILER CHICKENS using cold stress as a model.Design: Experimental study.Animals: A total of 300 day-old male Ross 308 broiler chickes.Procedure: Chickens were randomly divided into two equal groups, (control and test). chicks were reared for six weeks. Gradually Temperature was gradually decreased in the test group to 30% of the standard program from 2 nd week of the rearing period. At the end of each week, 5 chicks from each group were selected and electrocardiographic recordings were performed. Also after autopsy right ventricle / total ventricular weight was measured and recorded.Statistical analysis: t- student Test and Bivariate correlation.Results: There were significant elevation of the S wave amplitudes in 4th week (leads II, III, a VR) and 6th week (lead III). S wave had a significant correlation with RV/TV in 4th week (lead II) and 5th week (leads II, a VF) in the test group, too. There were also significant increase in the T wave amplitudes in 4th and 5th weeks (leads II, a VF) and 6th week (leads aVF, aVR) in the test group. In this study, R waves did not show a significant variation with the exception of 4th week (lead II).There were an elevation of MEA in test groups (with a right-cranial direction) but it just was significant in 4th week compared with control group.Conclusion: Electrocardiograms can be used effectively to evaluate the development of ascites syndrome in BROILER CHICKENS. The increase in the amplitude of Sand T waves could be considered as the sign of ventricular hypertrophy in ascites syndrome resulted from cold condition.
