Changes in the coagulation profile of cattle with left abomasal displacement

The purpose of this study was to determine changes in coagulation profile parameters in cattle with left abomasal displacement (LAD). The study was performed on 20 Holstein-Friesian (H-F) cows divided into two groups: group I--10 cows with diagnosed left abomasal displacement and group II--10 clinically healthy cows. Coagulation tests, including TT (thrombin time), PT (prothrombin time) and APTT (activated partial thromboplastin time), were conducted, and fibrinogen content, D-dimer content, AT III (antithrombin III) activity and platelet (PLT) count were determined in all the animals. Prolonged TT, PT and APTT, a higher fibrinogen and D-dimer content, a drop in AT III activity and thrombocyte count were observed in the cattle with LAD. The above abnormal coagulation profiles were most predominant in three cows which died after surgical repositioning of the abomasum. The results of the study indicate that in cattle with abomasal displacement, the disseminated intravascular coagulation (DIC) syndrome was the most significant risk factor for mortality.
