Canine Serum Metabolite Profiles from a 3-Month Plant-Based vs. Meat-Based Diet Trial

Serum metabolomics data for 61 healthy adult dogs fed either an extruded plant-based ('vegan') diet (n=31) or a commercial extruded meat-based diet (n=30) for 3 months. The dataset includes measurements of free amino acids, proteins, one-carbon metabolites, carbohydrates, fatty acids, and lipids taken at the start and end of the trial. It was authored by Sarah A.S. Dodd and harvested from the Borealis Dataverse platform, with a last update recorded in June 2026.

Use Cases

• Comparing serum amino acid and protein metabolite levels between plant-based and meat-based canine diets.
• Analyzing changes in fatty acid profiles and lipid metabolites over a 3-month feeding period.
• Investigating the relationship between dietary sulfur amino acid provision and corresponding serum metabolite changes.
• Studying the effects of diet on serum branched-chain amino acids (BCAA) and creatinine levels in dogs.

Strengths

• Data is from a controlled longitudinal trial with 61 dogs and measurements at two time points.
• Metabolite analysis covers multiple compound classes: 47 amino acid/protein, 16 carbohydrate, 29 one-carbon/folate, 61 fatty acid, and 78 lipid metabolites.
• The study design compared two nutritionally complete diets with similar total protein and fat levels, isolating the effect of ingredient source.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific analytical methods.
