  1. 1GS = gestation supplement treatment; LD = lactation diet treatment; Mod = moderate; PY = parity (1 or 2 =  ≥ 2); PD = period.
  2. 2DMI = DM intake; BW = body weight; ADG = average daily gain; BHB = β-hydroxybutyrate; NEFA = nonesterified fatty acids.
  3. 3Blood samples were collected in periods 2, 3, and 4.
  4. *Mean values of main effects are presented when there were no significant interaction effects (P > 0.05) involving the main effects. Otherwise, data are presented showing interaction effect (P < 0.05) or significant main effects (P < 0.05).
