Preservation of grass silage for improved protein quality to dairy cows
(PhD Thesis;2024:53, Doctoral thesis, 2024)Grass silage is an important feed protein source to ruminants in northern Europe in times when grazing is not possible. Improvements in the protein value and nitrogen (N) utilisation of grass silage could reduce feed cost, ... -
Strategies in silage production to mitigate enteric methane emissions from ruminants
(PhD Thesis;2024:30, Doctoral thesis, 2024)Emission of enteric methane (CH4) from ruminants have become a growing concern for policymakers globally as CH4 now account for 6% of global greenhouse gas (GHG) emissions and the warming effect in the atmosphere is 28 ... -
Cow-calf contact in dairy farming : Norwegian cowcalf contact (CCC) farmers’ practice and perceptions, and effects of CCC on behavior and performance on pasture
(PhD Thesis;2023:78, Doctoral thesis, 2024)The separation of cow and calf within the first day after calving is common practice in dairy farming, but cow-calf contact (CCC) systems are receiving increased attention from different stakeholders. This interest is ... -

Focal dark spots in the skeletal muscle of Atlantic salmon : involvement of rib abnormalities, environmental factors, and local immune responses
(PhD Thesis;2023:67, Doctoral thesis, 2023)Focal dark spots (DS) represent a major fillet quality issue, leading to significant economic losses in farmed Atlantic salmon (Salmo salar L.). DS typically appear as discoloured red/black areas in the anterior hypaxial ... -
Very-long-chain polyunsaturated fatty acids and their biological functions
(PhD Thesis;2023:83, Doctoral thesis, 2023)The overall aim of this thesis was to gain insight into the bioavailability of dietary very-long-chain polyunsaturated fatty acids (VLC-PUFAs) and their potential effects on skin and bone health. While well-known omega-3 ... -
Participatory and collaborative approaches in sustainability transitions : niche innovations in agri-food systems
(PhD thesis;2023:60, Doctoral thesis, 2023)Agri-food systems contribute to and face sustainability challenges across the entire value chain, from production, distribution, processing to retailing, consumption, and wastage. Organic farming, localized food systems, ... -
Evolution of flowering adaptations in temperate grasses
(PhD Thesis;2023:64, Doctoral thesis, 2023)Grasses (Poaceae) represent an unparalleled evolutionary success story and are particularly well adapted to the environmental challenges posed by temperate habitats. Crucial to their evolutionary success in temperate ... -
Genomic structural variations as drivers of adaptation in salmonid fishes
(PhD Thesis;2023:26, Doctoral thesis, 2023)Structural variations (SVs), e.g. deletions, insertions, inversions and duplications of sequences, are a major source of genomic variation affecting more base pairs in the genome than single nucleotide polymorphisms (SNPs). ... -
Forming links in the forage : a (meta)genome-centric metaproteomic approach to connect rumen microbial functions
(PhD Thesis;2023:59, Doctoral thesis, 2023)The rumen microbiome operates in close symbiosis with its ruminant host, where the rumen functions as a fermentation chamber for the conversion of complex recalcitrant carbohydrates into nutrients that represent the ... -
Alleles of adaptive importance for barley cultivation in a subarctic climate / Magnus Göransson
(PhD thesis;2023:51, Doctoral thesis, 2023)Barley is the most grown cereal in the Nordic countries, and the fourth most important cereal crop globally. Its use is mainly for feed, but a large portion is also used by the brewing industry. At northern latitudes, such ... -
Genetic diversity, selection signatures and nutritional composition of enset (Ensete ventricosum) from Ethiopia
(PhD thesis;2023:50, Doctoral thesis, 2023)Most of the agrobiodiversity exists in the form of landraces and wild relatives in traditional smallholderbased farming systems. This diversity mainly exists among neglected and underutilized species, so called orphan ... -
Grain yield in Norwegian spring wheat : past, present, and future : historical genetic gains, their genetic basis, and prospects of future improvement using phenomics
(PhD thesis;2023:52, Doctoral thesis, 2023)Bread wheat is among the most critical staples worldwide and is essential to Norway’s food production. The aftermath of the green revolution nearly eradicated Norwegian wheat production in the 1950s and 1960s. The lack of ... -
Using genome-wide associations, predictions, and selection to improve fusarium head blight disease resistance in wheat
(PhD thesis;2023:39, Doctoral thesis, 2023)Wheat is a well-adapted hexaploid crop and is a staple food for most parts of the world, commonly called bread wheat (Triticum aestivum L.). The history of first cultivation of wheat dates back to 10 000 years ago. It is ... -
Novel protein sources in diets for weaned piglets – effect on growth performance, gut function, and health
(PhD Thesis;2022:50, Doctoral thesis, 2022)The world is facing a growing food demand from an ever-increasing population. To meet this challenge, new resources must be utilized through innovative solutions. Meat is a valuable protein source in the human diet. However, ... -
Potato soft rot Pectobacteriaceae in Norway – seed potato health, association with insects and molecular mechanisms of disease development
(PhD Thesis;2018:92, Doctoral thesis, 2018)Soft rot Pectobacteriaceae are among the most problematic pathogens of a wide variety of crop plants and ornamentals. Among their hosts is potato, the most important food crop in Norway, where the bacteria cause soft rot ... -
The contribution of repetitive elements to salmonid genome evolution
(Phd Thesis;2022:72, Doctoral thesis, 2022)Eukaryotic genomes typically consist of a substantial proportion of repetitive DNA in the form of transposable elements (TEs) and satellite DNA. From studies of mammals, model species, and a few other well studied lineages ... -
Supplying dairy cows with Propionibacterium to reduce enteric methane emission
(PhD thesis;2021:16, Doctoral thesis, 2021)The primary target of this research was to explore the ability of promising propionibacteria strains to reduce the enteric methane emission from dairy cows. The second objective was to study the effect of propionibacteria ... -
Spodoptera frugiperda (JE Smith) (Lepidoptera: Noctuidae) in Benin: feasibility of biological control
(PhD Thesis;2022:73, Doctoral thesis, 2022)Since its outbreak in 2016 Spodoptera frugiperda (Lepidoptera: Noctuidae) commonly known as fall armyworm (FAW) has caused significant consequences on a range of crops, especially on maize, which is a staple food in most ... -
