Developing prediction equation for digestibility of nutrients in faeces from individual atlantic salmon
(Master thesis, 2015-11-19)The purpose of this study was to develop a robust and reliable approach to predict apparent digestibility coefficients of fat and protein of individual Atlantic salmon (Salmo salar), based on multivariate regression models ... -
Agroecological practices in a context of climate change in Africa
(Master thesis, 2015-11-06)Climate change effects are already being felt across Africa. Global warming, increasing rainfall variability and extreme events multiplication accentuate the risks for peasants who often already have to deal with natural ... -
De genetiske sammenhengene mellom hold ved avvenning på purker og produksjonsegenskaper hos råner
(Master thesis, 2015-11-06)Denne studien omhandler den genetiske sammenhengen mellom purkeegenskapen hold ved avvenning på førstekullspurker, og produksjonsegenskapene daglig fôrinntak(dfi), tilvekst og fôrforbruk (kg fôr) hos råner. Holdet til ... -
Comparison of vernalization response under natural and artificial climate conditions in Lolium perenne L.
(Master thesis, 2015-11-06)Forage grasses like perennial ryegrass (Lolium perenne L.) and Festulolium are extensively cultivated worldwide and constitute primary feed for ruminants due to their high nutrient value, high palatability and digestibility. ... -
Determining factors and trajectories analysis to support system diversification : mixed orchard animals and mixed orchard vegetables systems
(Master thesis, 2015-11-05)Fruit production is one of the largest users of pesticides among the agricultural productions, consequently leading to detrimental effects for environment quality and human health. In a context of pesticides use reduction ... -
Developing of a SNP based parentage testing panel in the Norwegian goat
(Master thesis, 2015-11-05)A parentage test for Norwegian goats consisting of 59 highly informative SNPs has been developed. A panel of 48 AI bucks genotyped by the Illumina 50K SNP chip were used to select 80 highly informative SNPs for the parentage ... -
Optimal process water supplementation and ratio between corn gluten meal and soy protein concentrate to secure good physical pellet quality and minimize energy use during extrusion processing of fish feed
(Master thesis, 2015-11-05)The objective of this experiment was to find out which combination of water/steam addition and plant protein ingredient mix that gives best physical quality and process economy. The design was, however, restrained by a ... -
The accuracy of across population genomic predictionusing a Bayesian variable selection model
(Master thesis, 2015-11-05)Background: The use of information across populations is an attractive approach to increase the accuracy of genomic prediction for numerically small populations. However, accuracies of across population genomic prediction, ... -
Effekt av separat avdeling ved AMS for mjølkekyr (Bos taurus) på ytelse, mastitt og fruktbarhet.
(Master thesis, 2015-11-04)Formålet med dette studiet var å undersøka utforming og bruk av separate avdelingar i AMS-besetningar i Noreg. Helse og produksjonparametrar vart nytta for å bestemme verknaden av separat avdeling ved AMS. Bønder vart ... -
Perception and sensoric quality difference of tilapia fish species in Morogoro Region, Tanzania
(Master thesis, 2015-11-04)This study aimed at evaluating consumer perception and quality preference of tilapia fish in the Morogoro region, Tanzania. For consumer preferences, a total of 85 respondents were interviewed from six wards of the Morogoro ... -
Genetic study on health and robustness in Norwegian Landrace
(Master thesis, 2015-11-04)For swine production to be as efficient as possible and to value animal welfare, it is important to have robust and healthy pigs. A breeding sow that can thrive and nurture healthy piglets in different environments is a ... -

A sociological approach to crop diversification
(Master thesis, 2015-11-04)Worldwide the diversity of cultivated plant species decreased for the past decades under the influence of the fast development of farming technologies. This lack of diversity has environmental impacts including water ... -
Variation in digestibility of protein and lipid among individual Atlantic salmon
(Master thesis, 2015-11-02)A group of 60 pit tagged post smolt Atlantic salmon chosen randomly from a pool of 50 families (34 represented), with an initial body weight of 440 g, were reared in a single tank for 56 days. Fish weight gain was 414 g ... -
Optimizing methods for isolation and in vitro cultivation of primary cardiomyocytes from Atlantic salmon (Salmo salar L.)---A study of cellular responses to hydrogen peroxide, lipo-polysaccharide and docosahexaenoic acid
(Master thesis, 2015-08-18)Atlantic salmon (Salmo salar L.) has been the most produced species in Norway. However, production related losses remain significant recent years, and a large proportion of this were due to viral diseases. Among these ... -
Protein content and gluten quality of Norwegian grown wheat influenced by fertilization
(Master thesis, 2015-08-18)Protein content and protein quality are important factors for bread making performance of the flour. The protein content widely varies between the types and classes of wheat, in amounts from 8-20%. It is strongly dependent ... -
