Aarhus University is heading a new project to investigate whether willow and hemp have potential as bioactive feed additives, which can inhibit methane emission from cattle. The project is an Organic RDD project supported by ICROFS, which started this year and runs until 2024. The project is carried out in collaboration with the Innovation Centre for Organic Farming, Ny Vrå Bioenergy, Bio2Products, Danish Technological Institute and SEGES.
