Table 1 Concentrations of plasma biomarkers at − 10 d relative to parturition in cows classified according to normal body condition score (BCS) (≤ 3.25, NormBCS; n = 30) or high BCS (≥ 3.75, HighBCS; n = 19) at 4 weeks prior to parturition

From: Maternal body condition during late-pregnancy is associated with in utero development and neonatal growth of Holstein calves
