RUSITEC Data on Seaweed Extract Effects on Rumen Fermentation and Methane Production

Two controlled experiments using the rumen simulation technique (RUSITEC) to assess the effects of liquid Ascophyllum nodosum extract on feed degradability and methane production. The dataset includes measurements of total gas, methane (mmol/d and mmol/g DOM), volatile fatty acids, and metabolic hydrogen recovery. Data was authored by Aaron Casey and last updated on 2026-03-25.

Use Cases

• Modeling the dose-response relationship of seaweed extract on methane production based on the described percentage of dry matter inclusion.
• Analyzing the impact of feed additives on metabolic hydrogen recovery based on the reported 22% decrease.
• Comparing the effects of different diet bases (grass vs. grass silage) on fermentation parameters and nutrient degradation.
• Training predictive models for volatile fatty acid production under controlled fermentation conditions.

Strengths

• Includes specific quantitative results, such as methane reductions of 20-34% and hydrogen recovery decreases of 22%.
• Data is structured from two distinct experiments with defined control and treatment groups.
• Published under a permissive CC-BY-4.0 license for reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small at 49.6 KB, indicating a limited scope of observations.
