Referentne vrijednosti za odabrane hematološke i biokemijske parametre u pelagonijske pramenka ovce

Abstract

The Ovcepolian type of Pramenka sheep is most prevalent in Pelagonia region. It is considered a valuable source of genetic diversity, characterised with a number of beneficial traits. Haematology and biochemistry measurements is important for health assessment of animals. The aim of this study was to determine the reference ranges for selected haematology and biochemistry parameters in the Pelagonian Pramenka sheep breed. The study was carried out on 55 clinically healthy, non-pregnant sheep, 1 to 3 years old, during spring season, from three different locations in the Pelagonia region, North Macedonia. Blood samples were collected from the jugular vein into vacuum tubes with an anticoagulant for haematological analysis and vacuum tubes free of anticoagulant for biochemical analysis. Reference values may be more adequate as it is later, for biochemistry parameters. Reference values for hematology parameters were: leukocytes, lymphocytes, midsize cells, cells correlating to monocytes, eosinophils, basophils, blasts and other precursor white cells, granulocytes, haemoglobin, haematocrit, erythrocytes, erythrocyte indices (average volume per litre, average haemoglobin in erythrocytes, average haemoglobin concentration per litre, and platelets). Reference values for biochemistry parameters were: total proteins, albumins, total bilirubin, total cholesterol, creatinine, glucose, HDL-cholesterol LDL-cholesterol, triglycerides, urea, aspartate aminotransferase, alanine amino transferase, alkaline phosphatase, glutamyl transferase, lactate dehydrogenase, and the concentrations of calcium, magnesium and inorganic phosphate. Most obtained values were comparable to other strains of Pramenka sheep. There was a clear deviation of certain reference values compared to the literature. Further analysis should be conducted to determine the reference values in rams and lambs.
