Table 3 Relative abundance (%) of the main bacterial taxonomic groups in representative fecal samples from Control and Peptiva-fed pigs in each of Phase II and III diets

From: Dietary inclusion of Peptiva, a peptide-based feed additive, can accelerate the maturation of the fecal bacterial microbiome in weaned pigs

  1. #Taxa showing a significant difference (P < 0.05) amongst means of different treatment groups
  2. See Supplementary File 3 for P values
  3. Means with different superscripts in the same row are significantly different as determined by the post hoc Nemenyi test for multiple pairwise comparisons
