Effect of grassland cutting frequency, species mixture, wilting and fermentation pattern of grass silages on in vitro methane yield
Weiby, Kim Viggo Paulsen; Krizsan, Sophie Julie; Dønnem, Ingjerd; Østrem, Liv; Eknæs, Margrete; Steinshamn, Håvard (Peer reviewed; Journal article, 2023)Mitigating enteric methane (CH4) emissions is crucial as ruminants account for 5% of global greenhouse gas emissions. We hypothesised that less frequent harvesting, use of crops with lower WSC concentration, ensiling at ... -

Kaczmarek-Derda, Wiktoria Anna; Østrem, Liv; Myromslien, Merete; Brandsæter, Lars Olav; Netland, Jan (Journal article; Peer reviewed, 2018)Increasing abundance of Juncus effusus (soft rush) and Juncus conglomeratus (compact rush) in pastures and meadows in western Norway has caused reductions in forage yield and quality in recent decades. Understanding plant ... -
