| Abstract | |
The serum biochemical profile is an excellent tool to identify any relevant physiological changes to health and calf welfare, especially in the neonatal period. This study aimed to evaluate serum biochemical profile of healthy buffalo calves in the neonatal period. Serum samples from 50 Murrah animals from a milk farm in the city of Alambari – SP were examinated. The animals were divided into three groups according to the number of parities of their mothers, 15 calves born from primiparous buffaloes (G1), 19 calves born from multiparous buffaloes with two to four parities (G2) and 16 calves from multiparous buffaloes with five to 14 parities (G3). The venous blood samples were taken at the following times: at birth, before the ingestion of colostrum (M0) at 24h (M1), 48h (M2) and 72h after birth (M3) and 7 (M4), 14 (M5), 21 (M6) and 30 days of age (M7) for determination of serum activities of gamma glutamyl transferase enzymes (GGT), alkaline phosphatase (ALP), aspartate aminotransferase (AST), creatine kinase (CK), and serum concentrations of total protein, albumin, globulin, iron, total calcium, ionized calcium, phosphorus, sodium, potassium. Serum concentrations of immunoglobulin G (IgG) were determined by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). The results were evaluated by analysis of variance (ANOVA) using the Tukey’s test to compare means, significance was observed at 5% probability. The age factor influenced all biochemical parameters, except for ionized calcium and potassium concentrations only from calves of G1 and G3 groups. The calving order of buffalo influenced AST, GGT, serum total protein, albumin, globulin and IgG of buffalo calves. The high serum ALP activity in the first two days after birth indicates the possible use of this parameter as an indirect method of assessing the passive immunity transfer. The serum iron concentrations of buffalo calves showed high values, the supplementation of this mineral is contraindicated in buffalo calves on the neonatal period. (AU) | |
