摘要：

This study describes the variation of serum biochemical metabolites during transition period in dairy cows. Blood samples were obtained on days 22 and 8 prepartum and days 7 and 21 postpartum (pp), to determine total protein, albumin, blood urea nitrogen, cholesterol, magnesium, inorganic phosphorus, calcium, glucose, triglyceride, aspartate aminotransferase (AST), β-hydroxybutyrate (BHBA), and non-esterified fatty acid (NEFA). NEFA concentrations during the pre-fresh period had a positive correlation with triglyceride, BHBA, and AST during post-calving days. This finding indicates that NEFA testing during the last days of a dry period is a reliable predictor of fat mobilization and energy status during this transition period. Serum glucose showed no strong correlations with other energy-related metabolites. AST was significantly correlated to triglyceride, BHBA, NEFA, cholesterol, and glucose at day 8 pp. AST also showed significant correlation with triglyceride concentrations at days -8 and +8 relating to parturition. In addition, AST was significantly correlated to BHBA and NEFA at day 21 pp. © Springer-Verlag London Limited 2007.
