The temporal expression pattern of MND1 and key regulators of floral transition in annual and perennial Pooideae species
(Master thesis, 2021)The molecular mechanisms underlying differences in annual and perennial life-history strategies are poorly understood. However, studies have shown that perennials often exhibit delayed flowering compared to related annuals. ... -
The domestication of Oreochromis mossambicus in a breeding program in Mozambique
(Master thesis, 2018)This study describes the establishment of a baseline and a base camp for the development of a genetic enhancement program for the Mozambique tilapia, Oreochromis mossambicus, with the scope of utilising both additive and ... -
The effect of tetradecylthioacetic acid (TTA) on body weight management in growing silver foxes (vulpes vulpes) as a model for dogs (Canis familiaris)
(Master thesis, 2018)This thesis consists of two parts, one general part concerning obesity and obesity related health problems in dogs. In addition, the general part gives an overview of methods to prevent obesity with restricted energy intake, ... -
The effects of environmental enrichments, group size and confinement length on play behaviour in juvenile Norwegian dairy goats (Capra hircus)
(Master thesis, 2018)Lek blir ofte betraktet som en indikator på god velferd i unge pattedyr siden det sjelden forekommer under vanskelige forhold. Det vil derfor være nyttig å vite hvordan endringer i noen normale produksjonsforhold påvirker ... -
The role of age in the selection of police patrol dogs using a standardized behavior test
(Master thesis, 2019)Police patrol dogs face many challenging situations, and only a proportion of dogs are suitable for this work. It is desirable to identify suitable dogs as early as possible, allowing unsuited dogs to be released for other ... -
The use of Saccharomyces cerevisae CNCM I-1077 in feed for ruminants : effect on digestibility, rumen enviroment and methane emmission
(Master thesis, 2019)The main objective of this experiment was to evaluate the effect of adding live yeast (Saccharomyces cerevisiae CNCM I-1077) in rations to dairy cows in early lactation on apparent total tract digestibility, rumen physiological ... -
Tipburn in lettuce (Lactuca Sativa L. ´Frillice´) : identifying climate factors that induce tipburn and cultivation methods that mitigate tipburn in controlled environment
(Master thesis, 2019)This master thesis is done with the aim of adding understanding to why tipburn occurs in greenhouse production of ´Frillice´ lettuce (Lactuca Sativa L. ’Frillice’), and to find cultivation methods can help reduce this ... -
Tracking GnRH neurons in vivo following CRISPR knock out of Six6 in Atlantic salmon
(Master thesis, 2021)Gonadotropin releasing hormone (GnRH) is a conserved neuroendocrine decapeptide, crucial for the onset of puberty and for the functioning of the hypothalamic-pituitary-gonadal axis (HPG). The homeodomain protein sine oculis ... -
Transfection optimization and gene editing method establishment for fish cells
(Master thesis, 2021)Aquaculture is one of the fastest-growing industries around the world, and salmonoid aquaculture is a very big industry for Norway. Ensuring fish health and welfare is essential for aquaculture, also to avoid economic loss. ... -
Transposable Elements as a Source of Novel Gene Regulation in Atlantic Salmon (Salmo salar)
(Master thesis, 2021)It has become evident over the last decade that transposable elements play an extensive role in gene regulatory evolution. Their ability to transpose close to genes, while also acting as cis-regulatory elements, permits ... -
Trends in runs of homozygosity and inbreeding in Norwegian Red Cattle before and after implementation of genomic selection
(Master thesis, 2020)Background: Despite commercial breeding being part of the genomic era, routine use of genotype data to govern inbreeding is still scarce. Recent studies have found acceleration of inbreeding rates after implementation of ... -
Using herd-averages of feed efficiency as training data for genomic selection
(Master thesis, 2021)Genomic selection on feed efficiency traits in dairy cows can save more feed costs and result in more sustainable dairy industry. Here we estimate the accuracy of genomic selection regarding dry matter intake in dairy ... -
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. ... -
Velferd på slaktegris : effekt av sosiale faktorer og fôringssystem
(Master thesis, 2020)Formålet med dette studiet var å undersøke hvor stor grad velferdsparametere påvirkes av dyretetthet, gruppestørrelse, bingedesign og fôringssystem. På grunn av økt fokus på dyrevelferd både hos forbrukere og autoriteter ... -
Vespa velutina predation impacts on Apis mellifera colony dynamics and reserves
(Master thesis, 2020)The honeybees play key environmental and economical roles as they contribute to the biodiversity preservation and to food production, through pollination. Nevertheless, Apis mellifera foragers are currently threatened by ... -
Weed invasion in different species compositions with and without perennial ryegrass
(Master thesis, 2018)Though perennial ryegrass (Lolium perenne) is a desired species in roughage production because of its nutritive qualities, it is not very persistent and - when used in species mixtures - often disappears after the first ... -
The welfare of finishing pigs : effects of air quality, environmental enrichment, and management
(Master thesis, 2020)It is highly important and necessary to document finishing pigs’ welfare, as healthy and happy pigs, with the ability to express their natural behaviour, will give good quality products to the consumers. A welfare ... -
What keeps dry petfood together? Optimizing homogeneity, extrusion melt and dehydration for best physical quality of petfood.
(Master thesis, 2021)Extrusion is the most common method for producing dry pet food. This technology involves various operations such as mixing, heating, kneading, shearing, and shaping. Obtaining extremely homogenous mixes of the ingredients ... -
When does the cat roam : temporal patterns of pet cat (Felis catus) roaming in Norway
(Master thesis, 2020)The domestic cats (felis catus) are popular pet animals, and their population is growing worldwide. As a natural predator, cats roaming outside raise conservation concerns. It is thereby important to know when and where ... -
