Summary
The Pig Gut Microbiome Dataset (PGMD) standardizes pig gut microbial data from over 12,000 samples. This resource aids research into precision feeding and improved pig health.
Area of Science:
- Animal Science
- Microbiology
- Bioinformatics
Background:
- The pig gut microbiome is vital for host health and agricultural productivity.
- Existing amplicon sequencing data lacks standardization, hindering comparative analysis and data reuse.
Purpose of the Study:
- To create a standardized, comprehensive resource for pig gut microbiome research.
- To facilitate comparative analysis and data reuse for improved pig health and precision feeding.
Main Methods:
- Systematic selection and curation of 202 publications with pig gut microbiome data.
- Manual curation of metadata and standardized reprocessing of 16S rRNA gene sequencing data.
- Integration of 12,336 samples from 22 countries, covering 52 host species and 3,028 taxonomic groups.
Main Results:
- The Pig Gut Microbiome Dataset (PGMD, version 1.0) is now available, integrating data from 207 BioProjects.
- The dataset is categorized by research topics and host phenotypes, enabling detailed exploration.
- Users can identify differentially abundant taxa, investigate phenotype-associated clades, and determine dominant taxa across growth stages.
Conclusions:
- PGMD significantly enhances the standardization and integration of pig gut microbiome data.
- This resource serves as a valuable tool for advancing precision feeding strategies.
- The dataset supports research aimed at improving overall animal health in swine populations.
