ABSTRACT:
This study evaluated the status of serum calcium in 39 Holstein cows with displacement of the abomasum (DA), from 30 dairy farms selected in the region of Campos Gerais, Paraná state, Brazil.. The diagnosis of abomasal displacement was performed by auscultation and percussion, besides the clinical signs and history information. Before surgery, blood samples were collected to measure blood levels of calcium, albumin, protein and glucose. As a control group, blood samples were collected from healthy cows that were in similar period of lactation. Of the 39 cows with abomasal displacement, 35 had hypocalcemia and in the control group only one cow. Blood glucose and protein concentrations were lower in the animals with DA when compared with the control group.
