Non-esterified fatty acids (NEFA; a) and β-hydroxybutyrate (βHB; b) serum concentrations in Nellore cows with different parity order under grazing according to the days relative to calving. Means with different superscripts differ from each other (P < 0.05). Days with asterisks (*) are significantly different between parities (P < 0.05)
