Background: Establishment of reference intervals (RI) for serum biochemical analytes is important for monitoring the health of different breeds of horses.
Objectives: The aim of this study was to measure and report RI for serum biochemical analytes of the Polish Konik horse.
Material and methods: Blood samples were collected from 74 clinically healthy Polish Konik horses living under controlled natural conditions. These were adult primitive horses, aged 3-15 years, including 28 males (21 stallions, 7 geldings) and 46 mares. Serum analytes were measured and analyzed using a commercial automated analyzer.
Results: The following RI (medians) were comparable to previously published RI in horses: albumin 34.8-41.3 g/L (38.0); ALP 124-309 U/L (216); ALT 6-33 U/L (19); AST 300-566 U/L (433); calcium 2.8-3.2 mmol/L (3.0); chloride 95-102 mmol/L (99); cholesterol 2.1-3.4 mmol/L (2.7); CK 167-488 U/L (328); creatinine 101-170 μmol/L (136); glucose 2.7-5.3 mmol/L (4.0); lipase 303-1143 U/L (723); magnesium 0.8-1.0 mmol/L (0.9); phosphate 0.9-1.5 mmol/L (1.2); potassium 2.4-5.0 mmol/L (3.7); sodium 138-144 mmol/L (141); total bilirubin 8-16 μmol/L (11.7); total protein 63.5-78.9 g/L (71.2); triglycerides 0.0-0.3 mmol/L (0.1); urea 2.2-7.3 mmol/L (4.7).
Conclusion: Reference intervals established in this study provide a valuable preliminary baseline for assessment of serum analytes in healthy Polish Konik horses.
