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, ... -
The accuracy of genomic prediction for viral nervous necrosis and vibrosis disease resistance in atlantic cod
(Master thesis, 2014-09-18)The objective of this study was to estimate accuracy of genomic prediction for disease resistance to viral nervous necrosis and vibriosis using sparse and genome sequence SNP-data in Atlantic cod. The disease challenge ... -
The effect of biochemical parameters on tenderness in beef
(Master thesis, 2012-09-06)The tenderness of beef is determined by the degree of myofibrillar toughness and content of insoluble collagen. The myofibrils and connective tissue and their degradation is largely determined by the amount of proteases ... -
The effect of dietary antioxidants on hyperpigmented fillet spots of Atlantic salmon (Salmo salar L.)
(Master thesis, 2016-08-18)Superficial discolored spots on Atlantic salmon fillets is a serious problem for the farming industry. Fillets with large dark stained spots are downgraded by the processing industry while smaller spots are removed, ... -
The Effect of Dietary Phytase Supplementation and Incubation in Soy Protein Concentrate based diet Fed to Nile Tilapia
(Master thesis, 2015-05-07)Aquatic feed require high quality, low cost nutrients with increasing aquaculture production. Tilapia has become the third most important cultured fish species in the world, just after salmonids and carps. Soybean and its ... -
The effect of experimental sleep restriction on pain inhibition is sex dependent
(Master thesis, 2014-01-29)Sammendrag Baggrund: I den norske befolkning er prævalensen af kronisk smerte på 30 %. For personer med kronisk smerte påvirker smerterne i høj grad både det sociale liv og arbejdslivet. Søvnkvalitet og -længde har vist ... -
The effect of granite grit on broiler chickens performance and gizzard development
(Master thesis, 2016-08-16)For å undersøke effekten kråsstein på slaktekyllingens ytelse og kråsutvikling, ble en omfattende studie utført ved Senter for Husdyrforsøk, ved Norges Miljø- og Biovitenskapelige Universitet i Ås, Norge. 252 dag gamle ... -
The effect of gritstone supplementation on performance and digestion in broiler chickens
(Master thesis, 2016-08-18)A study was conducted to investigate the effect of grit supplementation for broiler chickens’ performance and digestion. Three field trials were performed to observe the effect of insoluble quartz grit under commercial ... -
The effect of intermittent feeding on crop functionality and activity of exogenous non starch polysaccharides hydrolysing enzymes
(Master thesis, 2012-08-06)An experiment was conducted to investigate the effect of intermittent feeding, exogenous enzyme supplementation (xylanase and β-glucanase) and their interaction on the performance of broiler chickens. Furthermore, possible ... -
The effect of intermittent feeding on performance of broiler chicken and influence of oat hulls structure on diet flow
(Master thesis, 2014-02-18)Two trials were carried out to study the effect of intermittent feeding on performance of broiler chicken and passage rate of diet. In addition, interaction effects among feeding regime, oat hulls (OH) structure and phytase ... -
