About the position
The Department of Animal and Aquacultural Sciences (IHA), Faculty of Biosciences (BIOVIT) at the Norwegian University of Life Sciences (NMBU) has a vacant three year PhD–position related to research within the area of pasture grazing and feed additives as a greenhouse gas mitigation option in dairy and beef cattle production systems.
This PhD-project, Sustainable cattle production: grazing and feed additives as mitigation options in dairy and suckler cow production, is linked to the project MethanePasture - increased sustainability from dairy and meat from ruminants, funded by the Research Council of Norway (2023-2028). This project is conducted in close cooperation with partners from the dairy, meat, and feed industry (Animalia, Nortura, TYR, KLF, Tine, Felleskjøpet Fôrutvikling). The project also includes international collaboration with Agroscope (Switzerland) and Agriculture and Agri-Food Canada (Canada).
The main objective of MethanePasture is to improve the sustainability of ruminant livestock production, as well as national inventory and whole-farm greenhouse gas (GHG) estimates. This will be achieved by identifying the methane mitigation potential of pasture grazing and assessing the effectiveness of feed additives supplied to dairy cattle during both early and late pasture seasons. The expected outcome is to fill critical knowledge gaps regarding whether pasture grazing itself can reduce methane emissions, and whether methane-reducing additives show greater efficacy early compared to late in the grazing season—information that may offer practical and economic benefits to both society and industry.
The focus of the PhD position is twofold. First, the candidate will quantify enteric methane emissions from suckler cows grazing cultivated pasture and outfield pasture during early and late pasture seasons. This will be investigated in an experiment planned for summer/autumn 2026 using GreenFeed technology. The PhD candidate is expected to participate actively in this experiment, together with the project team. Second, the candidate will work with modelling greenhouse gas emissions using whole-farm models for cattle production systems. Based on data from the suckler cow experiment, as well as data from two completed dairy cow experiments in MethanePasture, the models HolosNor (dairy) and HolosNorBeef (suckler cow) will be improved to better account for grazing effects on enteric methane emissions. The net effect of different feeding strategies (pasture types, grazing vs. cut-and-carry vs. grass silage, and the use of feed additives) will also be explored.
The applicant is made aware that an application for a PhD position at NMBU is at the same time an application for admission to a PhD programme at the institution. The documentation that is necessary to ensure that the admission requirements are met must be uploaded as an attachment.
Main tasks
Take part in conducting an experiment with grazing suckler cows (measure methane emissions by using GreenFeed technology, body weight registrations, collect pasture samples)
Improve estimates of enteric methane on pasture in current whole-farm cattle models (dairy and suckler cow)
Estimate the net effect of pasture and feed additives on net farm GHG emissions from grazing dairy cows and beef cattle
Write and publish scientific articles in reputable international journals in collaboration with the supervisory group.
Participate in meetings with the industry partners in the project
Complete and submit a PhD-thesis within three years.
The successful candidate is expected to enter a plan for the progress of the work towards a PhD degree during the first months of the appointment, with a view to complete a doctorate within the PhD scholarship period.
