Alpha diversity of cecal microbiome of finishing turkeys at 2 d (A) and 7 d (B) after inoculation represented as Shannon diversity index. From the day of hatch, the poults were allocated into N, P, and S groups for 12 wk; ^a indicates P > 0.05. Abbreviations: N, Negative control (turkeys without SH challenge or PF supplementation); S, SH control (turkeys challenged with SH at wk 11 and without PF supplementation); P, test group (turkeys supplemented with PF for 12 wk and challenged with SH at wk 11); PF, Propionibacterium freudenreichii; S, SH control (turkeys challenged with SH at wk 6 and without PF supplementation); SH, Salmonella Heidelberg.
