Effects of extruded pellets on physical feed quality and digestion behavior in dairy cows
(Master thesis, 2018)This thesis consists of a literature study and a presentation of an experimental work. The literature review contains knowledge of raw ingredients, rumen digestion of starch and protein and feed processing techniques. The ... -
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 ... -
Effects of functional ingredients from yeast in diets for Atlantic salmon (Salmo salar), from two genetic backgrounds, on growth performance and nutrient utilization
(Master thesis, 2021)The overall aim of this thesis was to determine effects of functional ingredients in diets for Atlantic salmon, extracted from non- saccharomyces yeast, on growth performance and feed utilization. A 13 week (7 weeks in ... -
Effects of gamma radiation on growth and development in Arabidopsis thaliana
(Master thesis, 2015-07-28)Different types of abiotic stresses are known to have strong impact on morphological development of plants. Exposure of plants to ionizing radiation such as gamma radiation is potentially damaging, but effects may vary ... -
Effects of gradual adaptation to separation for calves on growth, feed intake and rumination in cow-calf contact system
(Master thesis, 2022)As animal welfare concerns are increasing, so is the interest in cow-calf contact (CCC). In CCC, the cow and calf go together for an extended period in dairy production. Compared to normal practice were the calf are separated ... -
Effects of light quality and temperature on elongation growth, dormancy and bud burst in Norway spruce (Picea Abies) and subalpine fir (Abies Lasiocarpa)
(Master thesis, 2015-07-16)Elongation growth and bud development in northern perennials is under photoperiodic control. This preparation for a colder season is induced by a shorter day than the critical day for growth and development. Light quality ... -
Effects of oil exposure and elevated temperature on the liver transcriptome in polar cod (Boreogadus saida)
(Master thesis, 2014-08-13)Expansion of petroleum-related activities in the Arctic has raised concerns about the environment and the adverse effects of potential oil spill on exposed Arctic marine organisms. Additionally, the Arctic is undergoing ... -
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 ... -
The effects of SNP-density and sample size on G-REML estimates of genetic and genic variance
(Master thesis, 2021) -
Effects of storage time, temperature and modified atmosphere on sensory quality and health related compounds in fresh-cut swede and turnip
(PhD Thesis;2015:9, Doctoral thesis, 2017-07-06)Introducing new fresh-cut vegetable products onto the market may increase vegetable consumption. Usually the availability of Norwegian grown vegetables for fresh-cut production is limited by a short growing season. However, ... -
Effects of supplement feed on cattle behaviour on pasture
(Master thesis, 2015-01-28)Genetics, supplement feed, environment, and management affect cattle behaviours and diurnal patterns on pasture, thus reflecting individual and/or group difference in time budgets. The aim of this study was to investigate ... -
Effects of temperature on dehydrin expression in mature somatic embryos of Norway spruce (Picea abies)
(Master thesis, 2018)Abstract: This master thesis deals with genetic and epigenetic effects in two genotypes (denoted A2K and B10) of in vitro derived somatic embryos (SEs) of Norway spruce (Picea abies (L.) Karst at different temperature ... -
Effects of the downstream processing of yeast on the gastrointestinal health of Atlantic salmon during seawater transfer
(Master thesis, 2021)Aquaculture intensification and sustainability concerns have prompted research into new feed ingredients, notably microbial ingredients such as yeast. Cyberlindnera jadinii (CJ) and Wickerhamomyces anomalus (WA) are among ... -
Effects of the soybean antinutrients saponin, isoflavonoid, and phytosterol on morphology and immune responses in the distal intestine of Atlantic salmon
(Master thesis, 2020)Two experiments were included in this study. The first experiment was designed to investigate the effects of the soybean antinutrients saponins, isoflavonoids, phytosterols and the mix of them on the distal intestine ... -
Effects of UV radiation and air humidity on morphology, stomatal function and photosynthesis of Euphorbia pulcherrima
(Master thesis, 2015-07-16)The combined effects of relative air humidity (RH) and UV radiation were tested on three cultivars of Euphorbia pulcherrima (Willd ex. Klotzch) at different ontogenetic stages in controlled environment growth chambers. In ... -
Effects of UVB light on laying hens and eggshell quality
(Master thesis, 2018)The effects of UVB lights on laying hens and eggshell quality were investigated in this study. UVB light treatment was provided by Philips TL 20W/12 RS SLV/25 tube light. The lights were on 2x30 min per day and were turned ... -
Effects of vaccination and dietary treatment on development and melanin deposition of Atlantic salmon (Salmo salar L.)
(Master thesis, 2014-08-13)Visual appearance is an essential quality property of food products. For salmonids the red color of the flesh is a main characteristic noticed by consumers, and fillets with discolored patches are downgraded. During recent ... -
