Fatty Acid Profiles and Carcass Traits for 265 Duroc Pigs

Supplementary file 1 from a study by Junhui Liu, last updated May 2026. The dataset integrates fatty acid composition from blood, liver, backfat, and muscle tissues and explores its relationship with carcass traits in 265 commercial Duroc pigs. It is shared under a CC-BY-4.0 license on figshare.

Use Cases

• Identify plasma fatty acid biomarkers for carcass traits based on the described correlation analysis.
• Model the relationship between tissue-specific fatty acid profiles and lean meat percentage based on the described negative correlations.
• Analyze inter-tissue communication of fatty acids like C16:0 and C18:1n 9 based on the described positive correlations.
• Predict muscle fatty acid composition using plasma indicators like C18:2n 6 based on the described predictive ability.

Strengths

• Includes data from 265 commercial Duroc pigs, providing a substantial sample size.
• Integrates multi-tissue fatty acid profiles (blood, liver, backfat, muscle) with carcass trait measurements.
• Specific correlation patterns between individual fatty acids and traits like carcass weight and lean percentage are described.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is contained in a 1.3 MB PDF file, which may require extraction to a structured format for analysis.
