【 摘 要 】

:The Criollo Lageano breed is an alternative for modern farming, due to its high genetic variability, rusticity and adaptation to environmental conditions of the Plateau of Santa Catarina, Brazil. These characteristics can influence important physiological events which should be investigated, because they can assist in developing future programs of animal breeding. It is known that failure of passive transfer (FPT) is an important factor for the increase in neonatal mortality in cattle. Thus, it is essential to evaluate aspects related to FPT in Criollo Lageano calves and the comparison with other beef breed created in the Plateau of Santa Catarina. Aiming to evaluate and to compare the passive transfer of immunity and serum protein concentrations, two experimental groups of 11 calves of Criollo Lageano (CL) hornless variety and 14 Aberdeen Angus (Red Angus) calves were selected. Blood samples were collected by jugular venipuncture for the measurement of total serum protein (TSP) by serum protein electrophoresis in agarose gel and the activity of gamma glutamyl transferase (GGT) and concentration of immunoglobulin G (IgG) by the method of the turbidity zinc sulphate, between 24 and 36 hours, 15, 30, 60, 90, 120, 150 and 180 days. Statistical analysis of data was performed by analysis of variance (ANOVA), Tu
