Pig Gut Microbiome Co-Abundance Networks Across Three Developmental Ages

Metagenomic analysis of 2,311 fecal samples from a genetically diverse pig population at 25, 120, and 240 days old. The dataset, authored by Yuxin Liu and last updated in April 2026, characterizes topological features and longitudinal dynamics of co-abundance networks involving beneficial commensal bacteria and their association with average daily gain.

Use Cases

• Analyzing age-specific topological changes in microbial co-abundance networks based on the three developmental stages described.
• Identifying microbial guilds associated with host growth performance based on the D120 stage data and its link to average daily gain.
• Studying the stability and variability of microbial correlations across host development based on the described cross-age network features.
• Inferring ecological interaction mechanisms within the gut microbiome using genome-scale metabolic models as mentioned in the description.

Strengths

• Dataset is based on a substantial sample size of 2,311 fecal samples.
• Longitudinal design covers three distinct developmental ages (25, 120, and 240 days) from pre-weaning to market.
• Analysis links microbial network topology to a measurable host phenotype (average daily gain).

Limitations

• Row count and specific column-level documentation are unknown, which may limit suitability assessment.
• The dataset is very small (34.6 KB), suggesting it contains summary or processed results rather than raw sequencing data.
• Description metadata is limited; actual data quality and field semantics require manual inspection after download.
