GWAS of Growth Traits in Danish Landrace, Yorkshire, and American Duroc Pigs

A genome-wide association study (GWAS) of growth traits in a multi-breed pig population. The dataset includes phenotypic and genotypic data from 823 animals (454 Danish Landrace/Yorkshire and 376 American Duroc) and 113,326 autosomal SNPs, identifying 24 significant SNPs and 66 candidate genes. It was authored by Xuancheng Guan and last updated on 2026-04-28.

Use Cases

• Identify genetic markers for growth efficiency based on age at specific weights (AGE100, AGE115).
• Investigate candidate genes for lipid metabolism based on backfat thickness measurements (BF100, BF115).
• Study the genetic architecture of birth weight (BW) using identified SNPs and genes like TCF7L2 and GART.
• Perform cross-breed genetic analysis to find stable loci across diverse pig populations.

Strengths

• Includes data from 823 animals across three distinct pig breeds.
• Analyzes 113,326 autosomal single nucleotide polymorphisms (SNPs).
• Identifies 24 significant SNPs and 66 candidate genes across five growth traits.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect breed and study population bias inherent to the source.
