Genome-Wide SNP Data for 5,859 Commercial Pigs from Three Breeds

A dataset from figshare contains genome-wide single nucleotide polymorphism (SNP) genotyping data for 5,859 commercial pigs. The data, generated by Chang Huang using a high-density SNP array and processed with PLINK, includes Duroc, Landrace, and Yorkshire populations. It was last updated on April 20, 2026, and is provided in VCF format for genetic analysis.

Use Cases

• Identify runs of homozygosity (ROH) based on the high-density SNP data mentioned in the description
• Analyze population structure and genetic diversity among the three pig breeds described
• Perform genome-wide association studies (GWAS) for production traits using the SNP genotypes
• Benchmark genomic selection models for livestock breeding programs

Strengths

• Contains data from 5,859 individual animals, providing a substantial sample size
• Covers three major commercial pig breeds (Duroc, Landrace, Yorkshire)
• Data was generated using a high-density SNP array, suggesting high genomic resolution
• Processed with standard bioinformatics tools like PLINK, indicating methodological consistency

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 source bias inherent to the specific commercial populations sampled
