This report reviews the potential use of seaweed as a feed ingredient for ruminants under Northern-Norwegian conditions. Seaweed has a long history in coastal livestock farming, especially where conventional forage was scarce, but its use declined as farms became larger, more specialised and dependent on high-quality feeds. Renewed interest is driven by the need to increase national feed self-sufficiency, reduce reliance on imported protein sources, and explore strategies to lower enteric methane emissions. Seaweed species differ greatly in nutritional value, digestibility, mineral composition and effects on rumen fermentation. Red species such as Porphyra and Palmaria palmata appear most promising as protein sources, whereas several brown species show lower protein digestibility and may contain high iodine levels or potentially harmful elements. Preservation is a major barrier because fresh seaweed decomposes rapidly; ensiling, drying and multi-nutrient blocks require further development to improve dry matter content, palatability, shelf-life and nutrient quality. Seaweed has also been studied as a methane inhibitor. Asparagopsis can strongly reduce methane emissions, but concerns about bromoform content, animal health, productivity and suitability for Norwegian systems limit its relevance. Norwegian studies with locally available seaweeds have not shown consistent in vivo methane mitigation. Overall, seaweed may support more circular and locally based feed systems, but practical use requires species-specific evaluation, safe inclusion levels, improved preservation methods and stronger in vivo documentation.
