The effect of Jersey in Norwegian dairy production
(Master thesis, 2022)Alterations in customer demands has the latest years increased the aggregate demand for milk fat from Norwegian dairy production. To encourage farmers to produce more milk fat, the premium for fat has been increased to ... -
Market gardening on micro-farms in the French Alps : the case of Beaufortain, France
(Master thesis, 2022)The Beaufortain is an alpine valley, located in Savoie, internationally known for the production of Beaufort PDO cheese since 1968. The arrival of the Projet Alimentaire Territorial (PAT) in 2020 has set in motion a ... -
Saccharina latissim in rations for dairy cows : effects on feed intake, milk yield and chemical composition of the milk
(Master thesis, 2022)As the world’s population is increasing, this sets demands to an increased food production. One way that Norwegian agriculture can meet these demands is to increase the use of naturally given resources in a sustainable ... -
The more the merrier? : the effect of group size on welfare, production results and carcass traits in fattening pigs
(Master thesis, 2022)Pigs in a commercial setting find themselves in group sizes that deviate from what is observed in the wild. Production pigs also lack the ability to regulate group size in accordance to available resources as they would ... -
Effect of access to dam on play behavior in dairy calves in a cow-calf contact system
(Master thesis, 2022)The common practice of immediate separation of cow and calf in dairy production is being questioned, and there is an increasing interest from the public and from the industry to assess alternative solutions for cow-calf ... -
Genetisk analyse av egenskaper fra eksteriørbedømmelse av islandshest på unghestskue og senere utstillinger
(Master thesis, 2022)Denne oppgaven ble formulert etter et ønske fra Norsk Islandshestforening. Hovedmålet med studien var å undersøke om noen av hestene som møtte på unghestskue i 2009 – 2011 hadde blitt stilt ut flere ganger, og om det var ... -
Characterization of genes and proteins related to chitin metabolism in Atlantic salmon
(PhD Thesis;2022:46, Doctoral thesis, 2022)Chitin is an insoluble polysaccharide and important component in the extracellular matrix of invertebrates such as arthropods, algae, and fungi. In vertebrates, the role and significance of chitin have not been deeply ... -
Rearing of Norwegian Red replacement heifers; Short- and long-term effects of dietary energy and protein levels on growth characteristics and adipose tissue gene expression
(PhD thesis;Thesis number 2019:12, Doctoral thesis, 2019)This thesis is part of a larger research project aimed at assessing the impact of calf and youngstock development on dairy cow production and profitability. The potential impact of heifer growth on future milk yield has ... -
The effect of freezing and thawing on water flow and pesticide leaching in partially frozen soil: Soil column experiments and model development
(;2019:20, Doctoral thesis, 2019)Increased pesticide concentrations have often been detected in soil leachate, drain discharge and surface runoff during freeze/thaw periods in late winter and early spring, both in Norway and Sweden. Limited knowledge and ... -
The genetics of omega-3 fatty acids in fillets of Atlantic salmon (Salmo salar L.)
(Doctoral thesis, 2019)Decreasing contents of the omega-3 fatty acids EPA and DHA in farmed Atlantic salmon reduces the nutritional value for consumers and influences physiological processes in the fish. Most studies of physiological omega-3 ... -
Ecological effects of Cytisus scoparius invasion : a native or alien species?
(PhD Thesis;2019:31, Doctoral thesis, 2019)The number of alien invasive species is continually increasing, threatening the environment and economy and their management is challenging. For cases of cryptic invasions, it is not even known if a species is native or ... -
Whole-farm modelling of greenhouse gas emissions from suckler cow beef production
(PhD Thesis;2019:93, Doctoral thesis, 2019)The main objective of this thesis was to develop a whole-farm model adapted to the various production systems and natural resources in Norway, estimate the level and variation in greenhouse gas (GHG) emission intensities ... -
Yeast (Cyberlindnera jadinii): an alternative protein source in pig and poultry feed
(PhD Thesis;2019:87, Doctoral thesis, 2019)The demand for food protein sources continues to increase rapidly along with the World population. Consequently, the European livestock industry requires a growing supply of feed protein to meet these demands. Furthermore, ... -
Towards a genome wide understanding of salmon lipid metabolism gene regulation across tissues and life stages
(PhD Thesis;2019:40, Doctoral thesis, 2019)Atlantic salmon is an important source of essential omega-3 fatty acids in human diets; however, omega-3 content in farmed salmon has been decreasing over the past decade due to the replacement of fish oil in aquafeeds ... -
Genomic prediction using high-density and whole-genome sequence genotypes
(Phd Thesis;2022:33, Doctoral thesis, 2022)The main objective of this thesis was to investigate genomic prediction methods for high-density and whole-genome sequence genotypes, with emphasis on traits that may have difficulties achieving a high prediction accuracy ... -
Can fish grow on trees? Nutritional and functional properties of yeasts in diets for Atlantic salmon (Salmo salar)
(Phd Thesis;2022:11, Doctoral thesis, 2022)Yeasts are gaining attention as alternative ingredients in fish feeds. The nutritional and health potentials of non-saccharomyces yeasts in fish are scarce in literature. Three non-saccharomyces yeasts; Cyberlindnera jadinii ... -
Genetic variation in recombination rates and genetic shuffling in pigs, cattle and Atlantic salmon
(PhD Thesis;2022:17, Doctoral thesis, 2022)Meiotic recombination ensures proper segregation of homologues chromosomes in meiosis while also breaking down linkage disequilibrium and creating novel haplotypes by shuffling alleles of genes located on the same chromosome. ... -
Novel indicator traits for individual feed efficiency in Atlantic salmon (Salmo salar)
(PhD Thesis;2019:02, Doctoral thesis, 2019)Selective breeding for enhanced feed efficiency in aquaculture production has so far been performed indirectly, largely through selection for an improved growth rate. However, a substantial fraction of the genetic variation ... -
Epigenetic and genetic adaptation in experimental yeast populations
(PhD Thesis;2019:23, Doctoral thesis, 2019)Evolution is a highly complex process where life change over time by the influence of relatively simple forces. Bringing evolution into the lab is a valuable asset to answer questions about processes that shape evolution. ...
