Plasma concentrations of fatty acids (a), hydroxybutyrate (BHB; b), glucose (c), and cholesterol (d) around parturition in cows overfed energy prepartum that developed ketosis within 7 days postpartum (KET) or remained healthy (OVE). *Means differ (status × time). Both groups of cows were fed a diet containing 1.54 Mcal/kg of dry matter and 15.0% crude protein from − 21 days prepartum to calving, and a common lactation diet containing 1.75 Mcal/kg of dry matter and 17.5% crude protein
