AbstractWith the purpose to evaluate the breed factor inf1uence on the hepatic function of cattle, 134 blood samples from, 67 Jersey and 67 Holstein cattle in São Paulo, Brazil, were collected . The hepatic function was studied through the determination of proteinogram; activities of the aspartate aminotransferase (AST), gamma glutamyltransferase (GG1) and dosage of total, direct and inditect bilirrubin in sorology .The evaluation of the proteinogram demonstrated the inf1uence of the breed factor: the values of total protein in Jersey (6.37±0.90 g/dl) was lower than in Holstein (6.82±0.97g/dl). The analysis of proteins showed the differences between the Jersey and the Holstein animals resulting of the globulins concentrations presents in serum, the values of globulins in Jersey (3.13±0..81g/dl) were lower than in Holstein (3.73±0.99g/dl). Values of alpha-, beta- and gamma-globulins were obtained through the eletrophoresis. In Jersey the values were lower (0.89±0,14g/dl; 0.71±0.14g/dl, 2.03±0.38g/dl) than in Holstein (1.00±0.16g/dl; 0.76±0.15g/dl; 2.20±0.45g/dl). The evaluation of breed factor inf1uence on the AST and GGT seric enzimatic activity showed this inf1uence in AST, but not in GGT. Values of AST in Jersey (49.27±17.87U/l) were higher than in Holstein (34.76±10.61U/l). Values of GGT did not show differences between the Jersey (19.46±33.11U/l) and Holstein (19.08±33.26U/l). The evaluation of seric bilirrubins concentrations showed differences on the total and indirect bilirrubin. Hygher values of indirect bilirrubin (0.40±0.33mg/dl; total bilirrubin 0.44±0.33mg/dl) were seen in Jersey than in Holstein.
