a
Value represented as least square means of main effects.
b
CC (milk replacer control; nursery control), CT (milk replacer control; nursery diet with tributyrin), TC (milk replacer with tributyrin; nursery control diet), and TT (milk replacer with tributyrin; nursery diet with tributyrin).
c
Feed efficiency = Average daily feed intake/average daily gain (day 22–58).
d
Effect of tributyrin inclusion in the milk replacer, in the nursery diet, and their interaction.
Bold values indicate the level of significance.
