A Correction on
Hydrolyzed protein formula improves the nutritional tolerance by increasing intestinal development and altering cecal microbiota in low-birth-weight piglets

by Bai, M., Liu, H., Yan, Y., Duan, S., Szeto, I. M.-Y., He, J., Hu, J., Fu, Y., Xu, K., and Xiong, X. (2024). Front. Nutr. 11:1439110. doi: 10.3389/fnut.2024.1439110

There was a mistake in Figure 3 as published. The image of RB41 was duplicated with the image of Rubrobacter. The corrected Figure 3 appears below.

Figure 3
A collection of scientific charts and plots displaying microbiome data. Panel A presents a Venn diagram with overlapping circles. Panel B features a PCoA plot with colored ellipses. Panel C is a stacked bar chart illustrating bacterial composition across different groups. Panel D includes five scatter plots comparing diversity indices such as observed species, Chao1, ACE, Shannon, and Simpson. Panel E displays stacked bar charts and scatter plots for bacterial phyla like Actinobacteriota and unidentified bacteria. Panel F shows similar visualizations for bacteria including Solobacterium and Rubrobacter, depicting relative abundances across groups BF, SF, and HF.

Figure 3. Effect of different formula treatments on colonic microbiota diversity and composition in pigs. (A) A Venn diagram illustrating the overlaps of OTUs in the gut microbiota. (B) Principal coordinate analysis (PCoA). (D) Non-metric multidimensional scaling (NMDS) analysis. (C) Unweighted unifrac cluster tree based on Unweighted Pair-group Method with Arithmetic Mean (UPGMA) analysis. (D) The microbial alpha diversity index (Observed-species, Chao1, Shannon, Simpson, ACE) were calculated using the mother program. (E) Relative contribution of the top 10 phylum in each group (left) and the relative abundance of significantly different microorganisms (right). (F) The relative contribution of the top 35 genera in each group (left) and the relative abundance of significantly different microorganisms (right). BF, basal infant formula; SF, standard premature infant formula; HF, hydrolyzed protein formula. Data are expressed as means ± SEM (n = 6). *p < 0.05, **p < 0.01, and ***p < 0.001.
