Genome editing for sustainability: Improving host resistance to combat late blight in potato and sea lice in Atlantic salmon
(Master thesis, 2021)Few species are as central to Norwegian society and culture as the potato and the Atlantic salmon. Yet these industries face considerable threats to production by pests, namely potato late blight (Phytophthora infestans) ... -
Factors affecting urea levels in goat milk
(Master thesis, 2021)The optimal milk urea level for Norwegian dairy goats is not known, and further study on the area is required if to be used as an indicator of efficiency in nitrogen metabolism. The aim of this study was to examine factors ... -
Evaluering av omregningsformler fra brystmål til levendevekt
(Master thesis, 2021)Denne oppgaven har to formål: å evaluere dagens tabeller for omregning fra brystmål til levendevekt, samt å undersøke dagens voksenvekter hos de fem kjøttferasen med nasjonalt avlsarbeid. Omregningstabellene Animalia bruker ... -
Disease development of Chondrostereum purpureum in common Norwegian plum cultivars
(Master thesis, 2021)Silver leaf disease, caused by the basidiomycete Chondrostereum purpureum, is a growing problem in Norwegian plum production. It affects the overall health and lifespan of the fruit trees. The inoculation experiments in ... -
Novel functional ingredients containing yeast cell wall components modulate molecular biomarkers in Atlantic salmon (Salmo salar) when exposed to acute hypoxic stress.
(Master thesis, 2021)Aquaculture is a continuously expanding global industry, however, some of the major problems associated with intensive fish farming are acute and chronic stressful conditions such as handling, sub-optimal nutrition, ... -
Summer Mountain Farming in Norway: Attendance Factors Among 'Seter' farmers
(Master thesis, 2021)Summer mountain farming (‘seterdrift’) in Norway is a transhumance practice in great decline. Being an extensive farming practice it relies on out-field resources in mountain areas and landscape areas and has been practiced ... -
Characterization of Functional Physical Properties of The Dry Pet Food Manufactured with Animal, Plant, and Microalgae Ingredients
(Master thesis, 2021)The aim of the thesis is to gain better understanding on the effects of defatted microalgae biomass (Desmodesmus sp.), vital wheat gluten and potato protein on physical qualities of extruded dry pet food. Two experiments ... -
In Vitro fermentation and In sacco degradation of the alkaline compound feeds in dairy cow diets
(Master thesis, 2021)The primary aim of this work was to test the in vitro fermentation kinetics and in sacco rumen degradation of different formulations of alkaline treated local grains in the dairy cattle diet, in contrast to soy-based ... -
Barriers to Crop Diversification Practices in the European Union: A Narrative Synthesis
(Master thesis, 2021)Crop diversification covers different farm-level practices such as extending crop rotations, intercropping, multicropping, and strip cropping. Irrespective of the well-documented farmlevel and societal benefits derived ... -
Effekter av ulike rotematerialer på atferdsmessige indikatorer og velferd for slaktegris
(Master thesis, 2021)Formålet med studiet var å undersøke hvordan ulike typer rotematerialer ville påvirke positive og negative atferder som indikatorer på velferd hos slaktegris. Vi ønsket også å undersøke om de ulike rotematerialene ... -
Transposable Elements as a Source of Novel Gene Regulation in Atlantic Salmon (Salmo salar)
(Master thesis, 2021)It has become evident over the last decade that transposable elements play an extensive role in gene regulatory evolution. Their ability to transpose close to genes, while also acting as cis-regulatory elements, permits ... -
Transfection optimization and gene editing method establishment for fish cells
(Master thesis, 2021)Aquaculture is one of the fastest-growing industries around the world, and salmonoid aquaculture is a very big industry for Norway. Ensuring fish health and welfare is essential for aquaculture, also to avoid economic loss. ... -
Identification of fungi that cause tip rot of carrot and determine effect of storage temperature and cultivar on tip rot development
(Master thesis, 2021)Carrot is one of the important vegetables in Norway, and after harvesting it stored in cold storage for up to 7 months. During such long storage time, there is great yield and quality losses due to various diseases, and ... -
Assessing the Effects of the New Atlantic Salmon (Salmo salar) Genome Assembly on Imputation Accuracy
(Master thesis, 2021-06-01)The Atlantic salmon is one of the most economically important species in modern-day aquaculture. For this reason, a lot of effort has been put into implementation and improvement of breeding programs for this species, ... -
Effects of functional ingredients from yeast in diets for Atlantic salmon (Salmo salar), from two genetic backgrounds, on growth performance and nutrient utilization
(Master thesis, 2021)The overall aim of this thesis was to determine effects of functional ingredients in diets for Atlantic salmon, extracted from non- saccharomyces yeast, on growth performance and feed utilization. A 13 week (7 weeks in ... -
Genetic analysis of lifespan in Irish wolfhounds
(Master thesis, 2021)Irish Wolfhounds are an ancient and large dog breed. Their lifespan is an average of 7 years only, which is associated with their size. The genetics behind the short lifespan and the combination with different known diseases ... -
The temporal expression pattern of MND1 and key regulators of floral transition in annual and perennial Pooideae species
(Master thesis, 2021)The molecular mechanisms underlying differences in annual and perennial life-history strategies are poorly understood. However, studies have shown that perennials often exhibit delayed flowering compared to related annuals. ... -
Characterisation of fructan accumulation in grasses and its implication for cold adaptation and overwintering
(Master thesis, 2021)Fructans are fructose-based oligo- and polysaccharides that occur in many plants in temperate climates. Beside its main function as storage carbohydrate, fructan has been suggested to play a role in temperate adaptations, ... -
