^aThe control diet (CON) was fed to all cows during the far-off dry period (−50 to −21 d relative to expected calving). During the close-up period (−21 d to calving) cows were assigned either to a higher-energy diet (OVE), OVE plus Smartamine M (OVE + SM) or continuously fed the CON diet
^bAll cows received the same lactation diet; however, Smartamine M (0.07 % of DMI) supplementation to the OVE + SM diet continued until 30 DIM
