Breeding for Milk Production in Sheep in Ethiopia
(Phd Thesis;2021:34, Doctoral thesis, 2021)The overall aim of this study was to investigate options to breed sheep for milk production and to find out the optimal proportion of Awassi in Local sheep breeds for milk production through the prevailing Community-Based ... -
Growth, hydraulic and transcriptomic responses to high air humidity and the involvement of abscisic acid (ABA)
(PhD Thesis;2021:65, Doctoral thesis, 2021)The aerial environment, which includes relative air humidity (RH), temperature, vapour pressure deficit (VPD) and CO2 availability, affects plant growth and development in many ways. The aerial environment determines ... -
Genetic studies of the wheat-Parastagonospora nodorum pathosystem
(PhD Thesis;2020:21, Doctoral thesis, 2020)Septoria nodorum blotch (SNB) caused by the necrotrophic fungus Parastagonospora nodorum is the major wheat leaf blotch disease in Norway. It reduces both yield and grain quality by causing symptoms on wheat leaves and ... -
Fungicide resistance and resistance dynamics in Botrytis populations in Norway
(PhD Thesis;2022:6, Doctoral thesis, 2022)Grey mould, caused by Botrytis spp., causes serious losses in agriculturally and economically important crops worldwide. Growers in Norway have experienced grey mould control problems, and fungicide resistance in the ... -
Alternative systems for Norwegian sheep production: extending fresh meat season and meeting niche market demands
(Phd Thesis;2020:49, Doctoral thesis, 2020)Norway has the largest sheep population (>1 million winterfed ewes) in Scandinavia. Sheep farming is taken as a part-time activity by most farmers. The focus of this PhD study has been on increasing year-round fresh meat ... -
Genetic analyses of semen characteristics in Norwegian Red
(PhD Thesis;2021:62, Doctoral thesis, 2021)The research on the genetics of bull fertility is limited, many studies are old, estimates are often based on few observations or few bulls, and with large or lacking standard errors. With more than 20 years of data on ... -
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 ... -
Quantitative genetics of growth rate and carcass quality traits in Atlantic salmon
(Phd Thesis;2021:39, Doctoral thesis, 2021-05-06)Quantitative genetic parameters of quality traits and growth rate in Atlantic salmon are commonly recorded at a target average market body weight (4-5 kg) at which the individuals are at the same age, which is less labour ... -
Genomic methods in breeding programs: Parental assignment, triploid genomics and case-parental control modelling
(Phd Thesis;2021:7, Doctoral thesis, 2021)The use of high-density single nucleotide polymorphism (SNP) genotypes enables us to perform highly accurate parentage assignment. However, dependence between loci often results in using a subset of the data to obtain ... -
Identification of photoreceptors with functional characterization of photolyase in Pseudoidium neolycopersici
(PhD Thesis;2021:72, Doctoral thesis, 2021)Powdery mildew caused by Pseudoidium neolycopersici is one of the most destructive diseases, occurring predominantly on greenhouse grown tomatoes, and has gained importance worldwide due to severe economic losses in terms ... -
A new approach for predicting milk production responses and feed utilization in dairy cows
(Doctoral thesis, 2021)Feed evaluation systems (FESs), such as the Nordic Feed Evaluation System (NorFor), aim to help dairy producers compare the nutritive value of various types of feed, formulate of balanced diets, and predict animal performance ... -
Reproductive and Genetic Studies in Large Yellow Croaker
(Doctoral thesis, 2021-12-15)Large yellow croaker (Larimichthys crocea) is distributed in the coastal regions of East Asia and is one of the most important marine aquaculture species in China. However, due to overfishing, it has been difficult to ... -
Mohairgeit i Norge – muligheter og utfordringer for fremtiden
(Master thesis, 2021)Kulturlandskapet i Norge er i sterk gjengroing. Geiter har et annet beitemønster enn sau og storfe, som er mer egnet til å åpne opp gjengrodde områder. I dag er melkegeiter de vanligste geitene i Norge. Siden markedet for ... -
Dietary effects on growth, skin morphology and stress marker genes of Atlantic salmon (Salmo salar L.) smolts
(Master thesis, 2021)The transfer of smolts from freshwater to saltwater is a challenging period during the commercial production of Atlantic salmon. The fish undergoes profound behavioural, developmental, and physiological changes. Additionally, ... -
Susceptibility of different apple cultivars to Codling moth (Cydia pomonella) and the factors that influence the infestation level
(Master thesis, 2021)Apple is the most cultivated fruit tree in Norway. However, due to many challenges, apple production is insufficient regarding the consumption requirements. Codling moth (Cydia pomonella) is one of these challenges, a ... -
Vektnedgang i smolt av Atlanterhavslaks (Salmo salar) - fra ferskvann til saltvann
(Master thesis, 2021)Atlanterhavslaksen er en anadrom fisk, som vil si at den vandrer mellom ferskvann og saltvann i forskjellige stadier i livet. Oppdrettslaksen blir flyttet fra ferskvann til saltvann når den går fra parr-stadiet til smolt. ... -
Developing a workflow for the multi-omics analysis of Daphnia
