Summary
This narrative review synthesises evidence on seaweed supplementation as a mitigation strategy for enteric methane emissions from ruminant livestock. The authors examine the biological mechanisms by which certain seaweed compounds (particularly halogenated compounds) may reduce methane production, whilst critically assessing practical challenges including consistency of seaweed composition, scalability of production, cost-effectiveness, and regulatory acceptance. The paper likely concludes that whilst seaweed shows promise as a methane-reduction tool, substantial research and development remain necessary before widespread agricultural adoption.
UK applicability
Given the UK's extensive dairy and beef sectors and climate commitments under the Agriculture Act, seaweed-based mitigation strategies are directly relevant to UK livestock farming. However, the UK's seaweed farming capacity and supply chain infrastructure would need significant development to support large-scale dietary supplementation programmes.
Key measures
Enteric methane emissions, seaweed dosage, ruminant diet composition, mitigation efficacy
Outcomes reported
The study examined seaweed as a dietary supplement strategy for mitigating enteric methane production in ruminant animals, evaluating both the potential effectiveness and practical challenges of implementation.
