a,b,c Means within rows with different superscript letters differ significantly (P < 0.05), whereas values with no letters or the same superscript letters are not significantly different (P > 0.05).

ADG, average daily gain; ADFI, average daily feed intake; FCR, feed-to-gain ratio; SEM, standard error of the mean.
