Insights into the regulation of LC-PUFA biosynthesis in wild and aquaculture Atlantic salmon in response to a vegetable oil diet
(Master thesis, 2018)The aim of this master thesis was to use transcriptomics to evaluate if lipid metabolism of wild and aquaculture salmon is different. In recent years, there has been extensive research on lipid metabolism in salmonids ... -
Intake of grass of Norwegian White Sheep and Old Norwegian Spæl – Are there breed differences in feed intake in a zero-grazing system?
(Master thesis, 2023)I Norge går sauen på beite om våren, sommeren og høsten, og i vinterperioden står de inne og blir fôret høstet grovfôr. Kunnskap om fôropptaket og faktorer som påvirker det er viktig for å sikre en bærekraftig ... -

Interactions between the cereal aphid pests Sitobion avenae and Rhopalosiphum padi and their fungal natural enemies
(PhD Thesis;2019:70, Doctoral thesis, 2019)In agronomy, efficient plant protection strategies are required to reduce pest pressure and increase crop yield. Pesticide application has been the dominant method for plant protection for almost a century. However, the ... -
Interactive effects of dietary and environmental challenges on digestive function and intestinal homeostasis in rainbow trout (Oncorhynchus mykiss)
(PhD Thesis;2016:82, Doctoral thesis, 2016)Aquaculture is challenged by various dietary and environmental factors. A widely debated and studied dietary challenge is the inclusion of plant ingredients containing anti-nutritional factors (ANFs) in salmonids diet. ... -
Interactive effects of light quality and temperature on bud set and shoot elongation in Norway spruce (Picea ables) and Subalpine fir (Abies lasiocarpa).
(Master thesis, 2017-06-08)In recent studies, temperature was shown to modulate the response to short days (SD) in woody species. This is an important issue for plant production in zones with marked seasons. Furthermore, light quality affects bud ... -
Interesse for et sunnere storfekjøtt blant forbrukere i Norge
(Master thesis, 2016-08-09)Inntaket av kjøtt er forventet å øke i takt med verdensvelstanden i framtiden. Hovedtrenden for mat i framtiden er å gå ‘back-to-basics’, med etterspørsel etter naturlige produkter med kjent opphav (Global 2015). Rødt kjøtt ... -
Investigating novel traits for pregnancy loss in Norwegian red cattle
(Master thesis, 2023)The task was to identify potential traits to describe the incidence of pregnancy loss in Norwegian Red cows. To evaluate the trait, variance components and heritability were estimated. Subsequently, a genome-wide association ... -
Investigating the need for and interest in offering honey bee pollination services in apple production : perspectives from growers and beekeepers in Midt-Telemark, Norway
(Master thesis, 2020)Studies show that having an abundance of honey bees, Apis mallifera, can increase yield and quality in fruit production. Managed honey bee pollination services may be a contributing factor to agricultural productivity. ... -
Investigation of the effect of different leguminous cover crops on the nitrogen use efficiency of spring barley
(Master thesis, 2017)The research focus was to investigate the effect of different Nitrogen Fixing Crops (NFC) used as green manure (GM) on the Nitrogen Use Efficiency (NUE) of spring barley (SB) (Hordeum Vulgare var Westminster), with different ... -
Investigation of the physiological basis of yield differences in Norwegian spring wheat
(Master thesis, 2018)Norway has a total land area of 324,000 km2 of which only 3% is arable. Moreover, the climate conditions allow a short growing season for agriculture. Despite these challenges, Government policies are directed towards ... -
Isolation and characterisation of bioactive components from Saccharina latissima and Alaria esculenta and their effect on proliferation and migration of intestinal epithelial cells (RTgutGC) in vitro
(Master thesis, 2018)The human population is projected to grow to 9.6 billion by 2050. This means increased demand for food, pharmaceuticals and feed for fish and farm animals. There is a high focus on meeting these demands by developing novel ... -
Kalsiumforsåpet rapsolje eller prosessert palmeolje som fettilsetning i kraftfôr til melkekyr : effekt på melkeytelse og melkens kjemiske sammensetning
(Master thesis, 2015-08-03)Kuas fordøyelsessystem er svært kompleks. Det er også overføringen av næringsstoffer fra fôr til melk. Det har lenge vært kjent at fôr og fôringsrutiner påvirker melkeproduksjonen. Fettilsetningen som benyttes i kraftfôr ... -
