ISSUE FOCUS 50 FEED & ADDITIVE MAGAZINE October 2025 Another key challenge is scale. Although global seaweed resources are abundant, much of the biomass remains untapped and the supply chain is still developing. OHT works in close partnership with suppliers and customers to expand both supply and demand simultaneously, creating scalable and sustainable systems that can meet the needs of modern livestock production. By building these networks, OHT is helping to unlock the full potential of this marine resource for animal nutrition. CONCLUSION Gut health is a critical priority for modern animal protein production, and seaweed—with its remarkable diversity of bioactive compounds—offers a natural and sustainable way to support it. While scientific literature is rich in evidence of these benefits, adoption in animal nutrition has been relatively slow. OceanFeed™ addresses this gap by using whole seaweeds from multiple groups, ensuring a consistent, 100% natural product that captures the full spectrum of functional compounds, delivering clear benefits for both animals and producers. At the same time, by harvesting invasive species, OceanFeed™ contributes to healthier marine ecosystems, supports the livelihoods of coastal communities, and achieves a negative carbon footprint across its full life cycle, making it a truly climate-positive innovation. By embracing blended seaweed solutions such as OceanFeed™, producers can capture the full benefits of this unique marine resource: Healthier animals supported by improved gut function, more efficient production through better feed conversion, and stronger environmental performance thanks to reduced resource use and a lower carbon footprint. At the same time, harvesting invasive species helps restore marine ecosystems and supports the livelihoods of coastal communities worldwide. In this way, OceanFeed™ delivers value across the entire chain — for animals, for producers, for consumers, and ultimately for the planet. References are available upon request.
