- Means in the same row with no superscripts or with a common superscript letter do not differ significantly (P < 0.05). Data are presented with the mean ± standard deviation (n = 6; pen was used as the experimental unit). NC = basal diet without supplementation; SNE = subclinical necrotic enteritis experimental model group; BS15 = basal diet with 1.0 × 106 cfu BS15/g diet as feed
