Gut Microbiota Profiles of 1,651 Commercial Boars Across Three Breeds

Shotgun metagenomic sequencing data from fecal samples of 1,651 commercial boars from three breeds (Duroc, Landrace, Large White) raised on three pig farms. The dataset, authored by Zikang Hu and last updated in May 2026, reveals differences in microbial composition associated with breed and age stage. It includes results from PERMANOVA and MaAsLin2 analyses identifying enriched bacterial taxa.

Use Cases

• Identify breed-specific microbial signatures based on taxa like Lactobacillus amylovorus and Akkermansia muciniphila.
• Analyze the variance in gut microbial composition explained by breed (2% to 9%) across different farms.
• Investigate age-associated microbial enrichment patterns across three developmental stages.
• Study the combined effects of genetic selection, age, and diet on the porcine gut microbiome.

Strengths

• Large-scale sample size of 1,651 boars, providing statistical power.
• Includes samples from three distinct pig breeds (Duroc, Landrace, Large White) across three farms.
• Analysis quantifies the effect size of breed on microbial variance (2%–9%).
• Identifies specific enriched bacterial species and families for each breed.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• The dataset is small (22.2 KB), suggesting it may contain summary or analysis results rather than raw sequencing reads.
• Geographic or farm-specific environmental details are not specified in the provided metadata.
