The aim of this study was to investigate the relationship between the loss in body condition score (BCS) and loss (ΔBCS), energy balance (EB), hepatic lipidosis and blood serum concentration of non esterified fatty acids (NEFA), glucose, triacylglycerol (TAG) and total bilirubin (tBIL) in healthy dairy cows during transition period. Twenty healthy Holstein cows were included and categorized into groups based on BCS loss (ΔBCS) between dry period and early lactation (ΔBCS <0.75 and ≥0.75). Significant differences between groups (p<0.05) were observed for blood serum NEFA, glucose and tBIL. Cows with high ΔBCS (≥0.75) between dry period and early lactation showed increased blood serum NEFA, TAG and tBIL concentrations and lower blood serum glucose concentration during transition period, compared to the low ΔBCS cows (<0.75). Metabolic profiles of cows during transition period indicate high level of lipid mobilization from adipose tissue, possible decreased liver cells TAG export and gluconeogenic ability and impaired bilirubin metabolism if ΔBCS is increased by more than 0.75 points. ΔBCS was in relation with energy balance (EB) in transition period.

Fifteen early-lactation cows and 15 mid-lactation cows were chosen for the analysis. Blood samples were collected to measure the beta-hydroxybutyrate (BHB), non-esterified fatty acids (NEFA), triglycerides (TG), glucose (Glu), total protein (TP), albumin (ALB), total bilirubin (TB), urea (U)and the activity of aspartate transaminase (AST) and gamma-glutamyl transferase (GGT). Earlylactation cows showed significantly higher (P<0.05) values of serum BHB and NEFA, and lower of (P<0.05) glycemia levels compared to mid-lactation cows. High lipomobilization (NEFA >0.4 mmol/l) and subclinical ketosis (BHB >1.2 mmol/L) were detected in 6 (40%) and 14 (94.4%) early-lactation cows, respectively, and in none of the mid lactation cows. AST activities above 100 IU/l were detected in two early-lactation and none of the mid-lactation cows. TG concentrations below 0.12 mmol/l were found in 7 (44%) early-lactation and 2 (13.3%) mid-lactation cows. Glucose levels were below 2.5 mmol/l in 10 (66.6%) early-lactation and 5 (33.3%) mid-lactation cows. Early-lactation cows showed lower blood serum concentrations of TG (P>0.05), ALB (P>0.05), TP (P<0.05), U (P>0.05) and GTT (P>0.05) activities and higher concentrations of TB (P>0.05) and AST activities (P<0.05),as compared to mid-lactation cows. These metabolic characteristics were correlated with DMI and energy balance (EB). Blood serum values for glucose, TG, BHB, NEFA and AST showed that earlylactation cows suffered from metabolic disturbances, associated with ketosis, and some degree of hepatic lesions, probably due to fat infiltration. These serum parameters may have a key role in evaluating the metabolic status of dairy cows.
