Establishment of a base population for long-term genetic improvement of Nile tilapia in Ethiopia
(PhD Thesis;2019:8, Doctoral thesis, 2019)The success of genetic improvement obtained in fish breeding programs depends on the genetic diversity of the founder populations and how the base population is constructed, as they influence the genetic variation of the ... -
Evaluating retch wire screen as a new tool for feces collection in digestibility assessment in fish: the impact of nutrient leaching on apparent digestibility of fishmeal, soybean meal and rapeseed meal diets in rainbow trout (Oncorhynchus mykiss)
(Master thesis, 2017)The study was carried out to evaluate the retch wire screen as a potential tool for collecting feces from water, by comparing its apparent digestibility estimates with that of the conventional stripping method. The retch ... -
Evaluation of the use of fractional abundance of stable carbon and nitrogen isotopes and indigestible inert marker in diets and faeces to calculate apparent digestibility of carbon and nitrogen
(Master thesis, 2018)The study carried out to test the feasibility of calculating apparent digestibilities (AD) of carbon and nitrogen with diets in fishmeal (FM), soybean meal (SBM), and rapeseed meal (RSM) as the main sources of protein by ... -
Faktorer som påvirker kalvingsegenskaper hos norske kjøttferaser og krysninger
(Master thesis, 2016-08-18)I dag er det stor underdekning av norsk storfekjøtt på grunn av redusert antall melkekyr uten tilsvarende økning i ammekutallet, samtidig som etterspørselen etter storfekjøtt har økt. Spesialisert kjøttproduksjon med ammekyr ... -
Farm-based education for food system transformation
(Master thesis, 2022)Food systems education is being studied as a “vital strategy” in transforming the current food system paradigm away from globalization and industrialization and towards a system which enables community-level food sovereignty, ... -
Field dissipation of pesticides used in Norwegian carrot production and pesticide residues in carrots in Norway compared to China, the European Union and Germany
(Master thesis, 2020)The use of pesticides has not only positive effects on yield and food safety but also poses a risk to the environment and human health. Residues of pesticides are frequently detected in food crops, water, and soil, but a ... -
Fillet quality and health of vaccinated or unvaccinated Atlantic salmon (Salmo salar L)
(Master thesis, 2015-12-14)The prime goal of the present study was to investigate the impacts of vaccine on biometric traits, melanization of tissues and fillet quality of Atlantic salmon (Salmo salar L). In the experiment, a total number of 420 ... -
Fillet quality of Atlantic salmon (Salmo salar) as affected by dietary and environmental treatments
(Master thesis, 2020)Fillet quality of Atlantic salmon (Salmo salar L) is crucial for both salmon producers and consumers. There are endogenous and exogenous factors that affect fillet quality. This thesis mainly focuses on exogenous factors: ... -
Fôropptak og endring i vekt og hold hos purker, og kullvekt ved avvenning i en formeringsbesetning
(Master thesis, 2014-02-14)Målet med denne masteroppgaven var å se om det var sammenheng mellom fôropptak og endring i vekt og hold hos purker og kullvekt ved avvenning i en formeringsbesetning. Oppgaven er basert på et litteraturstudie og en ... -
Fôrrasjonens effekt på pH-verdien og VFA-konsentrasjonen i blindtarmen, samt insulin og glukose i blodet hos hest
(Master thesis, 2015-07-02)Det har de siste årene vært et stort fokus på rasjonens effekt på hestens helse og prestasjon. Det er klare indikasjoner på at det er store fordeler med å gi mer fiber i forhold til sukker og stivelse i rasjonen til hest. ... -
Gelatinisation of starch in Nile tilapia feed
(Master thesis, 2015-07-27)The aim of study was to observe the effect of different levels of starch gelatinization in feed for Nile tilapia. Wheat was extruded with different moisture addition (20%, 25%, 30% and 35%), to tentatively obtain different ... -
Gene editing of red raspberry (Rubus idaeus L.) with CRISPR/Cas9 knocking out F3'H
(Master thesis, 2019)Breeding new improved crop varieties is a lengthy process that can take many years. With climate change and more rapidly changing environmental conditions, it becomes even more important to develop new varieties quickly. ... -
The genetic basis of partial resistance to powdery mildew in Norwegian wheat
(Master thesis, 2019)Powdery Mildew caused by (Blumeria graminis) is a major problem for cereal production, especially wheat (Tritium aestivum), and is an ever-occurring pathogen in Norway. One way for developing wheat cultivars with effective ... -
Genetic variation in susceptibility of Atlantic salmon (Salmo salar L.) to salmon lice, Lepeophtherius salmonis, from field and challenge tests
(Master thesis, 2018)Sea lice, Lepeophtheirus salmonis (L. salmonis) is the major threats for Norwegian salmon farming industry and the cost of the parasite was estimated to be around five billion NOK per year. Chemical treatments have been ... -
