Antimicrobial Efficacy of a Natural Feed Preservative in Compound Feed and Corn

David Díez Arias investigated the antimicrobial efficacy of Alquermold Natural Plus L (AMNL), a citric acid and monoterpene formulation, in animal feed matrices. The dataset likely contains results from tests against bacterial pathogens (Escherichia coli, Salmonella Typhimurium, Pseudomonas aeruginosa) and fungal contaminants (Aspergillus niger, Fusarium oxysporum, Rhizopus nigricans) at 24 hours and 7 days. The study was last updated on 2026-05-04 and is shared under a CC-BY-4.0 license.

Use Cases

• Compare the performance of natural versus synthetic feed preservatives based on the described efficacy testing.
• Model the effect of treatment and time on microbial reduction using the linear mixed-effects modeling mentioned.
• Assess antimicrobial activity across different feed substrates (compound feed and ground corn) as described.
• Evaluate the dose-response relationship for a citric acid-phenolic formulation based on the inclusion rates tested.

Strengths

• The experimental design is clearly described, including specific pathogens, contamination levels (10^6 CFU/g), and measurement time points.
• Results are compared against a commercial benchmark, providing a direct performance context.
• The dataset is licensed for open use under CC-BY-4.0.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (17.4 KB), indicating limited scope or summary-level data.
• Row count is unknown, which may limit suitability assessment for statistical modeling.
