^a,b,c,d Means within the same row with no common superscripts differ significantly (P < 0.05).

Values are means (n = 6) and standard error of means (SE).

Dietary treatments: NC, negative control, with no additives added to the basal feed, water and litter; PC, positive control, with the antibiotic, zinc-bacitracin (ZnB, 50 mg/kg) added in feed; Oral-NC, negative control, with no additives added to the basal feed, water and litter, orally inoculated with PBS solution; Other treatments, with probiotic (Pro) L. johnsonii delivery by oral gavage, feed, water and litter, respectively.
