Values of P < 0.05 indicate significant differences. The blood glucose, total cholesterol (T-cho), blood urea nitrogen (BUN), non-esterified fatty acid (NEFA), and β-hydroxybutyric acid (BHBA) concentrations were analyzed at 3 weeks (W-3) and 1 week (W-1) prepartum and 3, 5, and 7 weeks (W3, W5, and W7, respectively) postpartum. The body condition scores (BCS) were evaluated at W-3, W3, and W7.
