Abstract :
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
