N2 - New and refined techniques have been developed for cultivation of marine plant biomass (macroalgae, alsocalled seaweed), and the future production potential is expected to exceed that of terrestrial plants by 10-fold or more. Macroalgae species are categorized into brown, green and red macroalgae, which containcarbohydrate and protein fractions that are distinctly different from those of terrestrial plants. Within thesethree main categories, it is possible to find species that have sufficiently high protein contents and organicmatter digestibility to make them interesting as alternative, new protein feeds for ruminant livestock –provided they can be marketed at competitive prices in the future. Seaweeds and seaweed extracts havebeen shown to reduce methane and increase feed degradation in ruminants. Additionally, they can be avaluable source of protein. Specific Nordic species have been tested in the lab at the University ofCopenhagen, Department of Veterinary and Animal Sciences, showing promising results. In this way,seaweed as ruminant feed addresses two challenges of ruminant production: methane mitigation andprotein supplementation. However, there is a distance from scientific lab results to marketable, validatedproducts and we will address this in a CLIMATE KIC ideation project together with 2-3 Norwegian seaweedproducers. During this project, we will focus on the challenges facing nutritional and feeding validation aswell as product development and formation.
