Effects of Magnesium Potassium Sulfate on Tibetan Sheep Meat Quality and Metabolites

A metabolomics study investigating the effects of dietary magnesium potassium sulfate (PMS) on Tibetan sheep meat. The research measured carcass quality, meat pH, intramuscular fat, fatty acid profiles, and volatile compounds. The dataset, authored by Yuan Wang and last updated in May 2026, is associated with a CC-BY-4.0 licensed supplementary document.

Use Cases

• Modeling the relationship between dietary mineral supplements and carcass quality metrics based on reported abdominal and backfat thickness changes.
• Analyzing flavor profile changes in meat based on volatile compound data for fruity/nutty and malodorous substances.
• Investigating fatty acid biosynthesis pathways in livestock based on reported concentrations of linoleic acid, linolenic acid, EPA, and DHA.
• Studying the sphingolipid signaling pathway's role in meat quality regulation as suggested by the metabolomics results.

Strengths

• Includes specific, statistically significant results (e.g., 13.13% increase in abdominal wall thickness, p < 0.05).
• Applies a multi-faceted analysis covering carcass quality, nutritional composition, and flavor metabolites.
• Uses a metabolomics approach to explore underlying biological mechanisms.

Limitations

• The primary data file is a 2.2 MB DOCX document; the underlying structured data tables are not directly available.
• Column-level documentation is absent; field semantics must be inferred from the article text.
• Row count is unknown, which may limit suitability assessment for large-scale analysis.
