SEM = standard error of the mean; DM = dry matter; Total DMI = total DM intake; ME = metabolizable energy; CP = crude protein; NDF = neutral detergent fiber; NFC = non-fibrous carbohydrate.

¹SFC: starter diet containing SFC (65.7% of DM) without SBP; SBP: starter diet containing SBP (25% of DM) as replacement for SFC (43.5% of DM).

²Feed efficiency was calculated by dividing average daily gain by average total DM intake (milk replacer DM + starter feed DM) or total ME intake (milk replacer ME + starter feed ME).
