Figure 5.

A network showing the potential effective mechanism of early nutrition promoting the homeostasis of the chicken intestinal microbiome. The edge in red or blue represent the positive or negative correlation between the microbial species and the treatments (Spearman's rank correlation coefficient). All the species represented nodes are colored in blue and all the SCFA represented nodes are colored in orange. The factors of COS and CPS represented nodes are colored in red and green. The node sizes are proportional to the mean abundance in the respective factors. Abbreviations: COS, chitooligosaccharide; CPS, chlorella polysaccharide; SCFA, short-chain fatty acid.
