SERUM BIOCHEMICAL PROFILE OF NELLORE AND GIROLANDO COWS RAISED IN STATE OF MARANHÃO

Authors

Abstract

Abstract
The aim of this research was to evaluate serum activities of aspartate aminotransferase (AST),
alkaline phosphatase (ALP), creatine kinase (CK), gamma-glutamyltransferase (GGT), and on serum
concentrations 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 automatic
ion analyzer. Assessment of enzyme activity showed the influence of racial factors in the results of
CK, the values of Nellore cows (87.5 U/L) being higher than the Girolando cows (68.6 U/L). Serum
levels 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: 1.47
mg/dL, TB: 0.23 mg/dL and UB: 0.14 mg/dL), except for ionized calcium (Nellore: 0.66 mMol/L and
Girolando: 0.73 mMol/L). The results evidenced the influence of racial factor on some biochemical
parameters, and, therefore, should be taken into consideration for correct interpretation of laboratory
tests.
Keywords: bovine, clinical biochemistry, racial influence, reference values.
