Abstract

Because displacements of abomasum cause great economical losses in Southern Turkey and can be complicated by lethal abomasal torsion, the objectives of this study were to evidence the main haematological and biochemical alterations occurring in right displacements of abomasums (RDA) with only dilatation. Haematological and biochemical parameters in blood and urine were investigated in 48 Holstein cows from the Burdur region diagnosed with simple RDA. Body temperature, heart and respiratory rates were also examined. RDA occurred mainly within the 4th lactation of cows, during winter and on animals fed with a diet regimen enriched with concentrates. Body temperature, and heart/respiratory rates were altered according to the severity of the disease. Except leukocytosis associated with increased lymphocyte, monocyte or neutrophil counts observed in the early stages or in cows with secondary infections, haematological parameters were usually within the normal ranges. Marked decreases of plasma electrolyte concentrations (hypochloremia, hypokalemia, hyponatremia and hypocalcemia) were commonly found with incidence of 89 - 93% and were associated with metabolic alkalosis revealed by urinary high pH (in 90% of cases) and by high blood pH values (in 62.5%). Hyperglycaemia (in 100%) coupled to a marked to severe ketonuria (in 90%) as well as to increases of plasma AST activities (in 90%) were considered as high sensitive markers of RDA and suggested the exacerbation of the liver metabolism.
