(Master thesis, 2016-02-15)The aim of present study was to evaluate Vital wheat gluten (VWG) as protein source in comparison with high-quality fish meal (LT-FM) and soy protein concentrate (SPC) in extruded diets for juvenile Giant croaker (Nibea ... -
Det sosiale båndet mellom menneske og katt
(Master thesis, 1998)Etterhvert er man blitt mer klar over kjæledyrets rolle som sosial partner, og ikke bare som et slags terapeutisk objekt. I 1994 utførte Zasloff og Kidd en spørreundersøkelse i USA for å øke kunnskapen om forhold mellom ... -
Forskjeller i atferd mellom tre katteraser: arvbarhet av noen atferdsegenskaper, og eierens forhold til sin katt
(Master thesis, 1998)Det ble sendt ut spørreskjemaer til eiere av siameser, perser og vanlig huskatt. Jeg ønsket å finne ut om det var forskjeller i atferdsegenskaper mellom de ulike katterasene. For å kunne beregne arvbarhetsestimater for ... -
Fillet quality and health of vaccinated or unvaccinated Atlantic salmon (Salmo salar L)
(Master thesis, 2015-12-14)The prime goal of the present study was to investigate the impacts of vaccine on biometric traits, melanization of tissues and fillet quality of Atlantic salmon (Salmo salar L). In the experiment, a total number of 420 ... -
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 ... -
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 ... -
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, ... -
