The aim of this study was to determine the changes in the plasma lipid profiles in the cows withtraumatic pericarditis. The study was performed on 10 cows with traumatic pericarditis, 3-6 yearsold, brought into the Clinic of Internal Medicine, Faculty of Veterinary Medicine, University of Firat and 10 healty controls.

The level of CHOL (P
