A basic model to predict enteric methane emission from dairy cows and its application to update operational models for the national inventory in Norway
Niu, Puchun; Schwarm, Angela Dagmar; Bonesmo, Helge; Kidane, Alemayehu; Åby, Bente Aspeholen; Storlien, Tonje Marie; Kreuzer, Michael; Alvarez Flores, Maria Clementina; Sommerseth, Jon Kristian; Prestløkken, Egil (Peer reviewed; Journal article, 2021-06-25)Many techniques exist to quantify enteric methane (CH4) emissions from dairy cows. Since measurement on the entire national cow populations is not possible, it is necessary to use estimates for national inventory reporting. ... -
