Development of winter wheat and weeds in organic reduced tillage
(Master thesis, 2014)No-tillage and reduced tillage are soil conservation techniques directed to reduce soil erosion and to enhance soil fertility. These techniques are adopted into conventional agriculture where weeds are controlled with ... -
Effects of fat soluble vitamins on viral infection and antiviral responses in Atlantic salmon (Salmo salar L.) erythrocytes
(Master thesis, 2017)Viral diseases are vital challenges in the aquaculture industry. In Norway, heart- and skeletal muscle inflammation (HSMI) is one of the major viral diseases affecting Atlantic salmon. In mammals, low vitamin D has been ... -
Chemical changes seen in protein during pelleting : a literature review
(Master thesis, 2017)Pelleting induced changes in protein denaturation with exposure to heat is to milder level. Denaturation of protein showed better digestibility of protein molecule. Change in the secondary structure i.e. alpha helix, beta ... -
Which is the future for ICTs-based services in agricultural extension in India?
(Master thesis, 2017)This report aims to deliver a state-of-the-art of new opportunities in information dissemination in rural India. Today, agricultural information transfer mechanisms are mostly generated by the public agricultural extension ... -
Genetisk variasjon og clusteranalyse på bakgrunn av slektskapsdata hjå dølahest
(Master thesis, 2017)Formålet med denne oppgåva var å analysere genetisk variasjon hjå dølahesten, å sjå på slektskapsstruktur i rasen ved hjelp av clusteranalyse, samt å sjå på moglegheiter for gode strategiar for berekraftig avl i framtida. ... -
Effects of replacing fish oil with microalgae biomass (Schizochytrium spp) as a source of n-3 LC-PUFA to Atlantic salmon (Salmo salar) on growth performance, fillet quality and fatty acid composition
(Master thesis, 2017)Low levels of EFA in fish feed as a result of changes in diet composition brings a need of finding a novel ingredient that will supplement Essential Fatty Acids (EFA) in fish feed. Microalgae have ability of producing ... -
Pork quality and boar taint as important issues in modern swine production
(Master thesis, 2017)The objective of this study was to analyze and criticize the published literature related to pork quality in male pigs, in modern swine production. There are different types of quality and different factors that can ... -
Effekt av høstetid og valsing på fordøyelighet av surfôr av hvete helgrøde hos melkekyr
(Master thesis, 2017)Effekten av høstetid og valsing på tilsynelatende in vivo fordøyelighet av surfôr av hvete helgrøde ble undersøkt ved å ta utgangspunkt i et fordøyelsesforsøk med 8 melkekyr i sen laktasjon i 4 x 4 latinsk kvadrat. Kyrne ... -
Breeding of Begonia tuberhybrida using modern biotechnology
(Master thesis, 2017)Tuberous begonias (Begonia tuberhybrida) are popular ornamental bedding plants, of which approximately 300 000 units are being produced in Norway each year, and novel cultivars are a Norwegian export article. Blue and ... -
Characterization and expression analysis of the key genes for early development of swim bladder in Atlantic cod
(Master thesis, 2017)Some genes have been proved critical for swim bladder inflation during early stages. Hence, our researches were focused on the investigation into the genetic features of the key genes to early development of Atlantic cod ... -
Survey report on the potential of establishing tilapia farm in Ivory Coast
(Master thesis, 2017-12)This report was made during a 7 month survey on the potential of establishing tilapia farm in Ivory Coast. The aim of the report is to be a source of information on the technical and social aspects of establishing a tilapia ... -
Reconstruction and modelling of amino acid synthesis in Salmo salar
(Master thesis, 2018)This thesis documents the process behind the reconstruction of the Salmo Salar Amino Acid Synthesis model (SalSAA). The model is a mathematical description of amino acid biosynthesis and protein polymerisation in Atlantic ... -
Beskrivelse av ulike driftsformer av slaktekylling i Norge
(Master thesis, 2018)Consumers have become more concerned with the production of food, quality of the meat and animal welfare. Conventional production with fast-growing breed has been the only production form of broiler chicken. However, ... -
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 ... -
Estimation of endogenous loss from soy variants using the 15N isotope dilution method in Atlantic salmon (Salmo salar)
(Master thesis, 2018)True digestibility of feeds and feed ingredients is difficult to measure in fish, partially due to methodological challenges in quantifying endogenous losses that are mixed with undigested materials originating from the ... -
