1Means in the same row with no superscript or with a common superscript letter do not differ significantly (P < 0.05). Data are presented as mean ± standard deviation (n = 6; a cage was regarded as one experimental unit). Control group = basal diet without supplementation; LJ group = basal diet with 1.0 × 106 cfu LJ/g diet as fed; D-LJ group = basal diet with 1.0 × 106 cfu disrupted LJ/g diet as fed.
2ADFI, average daily feed intake; ADG, average daily gain; FCR, feed conversion ratio (ADFI/ADG).
