The vision is to reduce imported soybean and develop a sustainable and locally produced animal feed from marine substrate such as microalgae and blue mussels for the poultry industry. Algae have a good potential to be a feed ingredient due to high protein, essential dietary amino acids and oil levels. Mussel meal can replace soy in poultry diets, and can be a high quality protein source for broilers. Using algae and mussels in animal feed contribute to sustainable development, and eutrophication and climate change mitigation efforts. Algae can be produced in Southeast Sweden, recycling carbon dioxide from power plants, and recovering nutrients from various waters. Mussel farming can act as a nutrient sink when harvested in the Baltic Sea and reduce local eutrophication. In this project, academia, farming and the poultry industry join in a multidisciplinary collaboration to demonstrate at the pilot scale the feasibility of using microalgae and mussels as ingredients in chicken feed.
