AbstractThe aim of this research was to evaluate serum activities of aspartate aminotransferase (AST),alkaline phosphatase (ALP), creatine kinase (CK), gamma-glutamyltransferase (GGT), and on serumconcentrations of albumin, bilirubin, total and ionized calcium, cholesterol, creatinine, phosphorus,magnesium, potassium, total protein, sodium, triglycerides, and urea of Nellore (n=120) and Girolando(n=120) healthy cows, aged 24 to 36 months, using a semiautomatic spectrophotometer and automaticion analyzer. Assessment of enzyme activity showed the influence of racial factors in the results ofCK, the values of Nellore cows (87.5 U/L) being higher than the Girolando cows (68.6 U/L). Serumlevels of creatinine (Crea), total bilirubin (TB), unconjugated bilirubin (UB) and ionized calcium were also influenced by breed, and the values obtained for the Nellore cows (Crea: 1.61 mg/dL, TB:0.28 mg/dL and UB: 0.19 mg/dL) were higher than those observed for Girolando cows (Crea: 1.47mg/dL, TB: 0.23 mg/dL and UB: 0.14 mg/dL), except for ionized calcium (Nellore: 0.66 mMol/L andGirolando: 0.73 mMol/L). The results evidenced the influence of racial factor on some biochemicalparameters, and, therefore, should be taken into consideration for correct interpretation of laboratorytests.Keywords: bovine, clinical biochemistry, racial influence, reference values.
