Accuracy of genomic prediction using group recordings
Adhikari, Niran (Master thesis, 2022)Group records are the alternative solutions for traits that are affected by group interaction and are difficult or costly to measure on individuals. We aimed to investigate how group size, group composition, and validation ... -
The effects of SNP-density and sample size on G-REML estimates of genetic and genic variance
Magwaba, Tapiwanashe (Master thesis, 2021) -
Genetic analyses of feed efficiency traits in pigs
Martinsen, Kristine Hov (PhD Thesis;2016:55, Doctoral thesis, 2017-12-12)The main objective of this thesis was to establish more detailed measurements feed efficiency in Norwegian Landrace and Norwegian Duroc in order to genetically improve this trait without negative consequenses for other ... -
Genomic predictions including known QTL for reproduction traits in swine
Häfliger, Irene (Master thesis, 2016)Breeding values are the fundament on which the selection of the next generation is based on and should therefore be as reliable as possible. The implementation of marker-assisted selection (MAS), where major genes are ... -
Modeling feed intake and feed efficiency along the lactation curve of Norwegian Red Dairy Cattle
Obari, Christiana Onyinoyi (Master thesis, 2021)Including feed efficiency into breeding goals could be a key in ensuring sustainable dairy cattle production as selection could be based on how efficient a cow is in terms of what it consumes and produces all through the ... -
Non-additive genetic effects in Nile tilapia
Joshi, Rajesh (PhD Thesis;2018:101, Doctoral thesis, 2018)Nile tilapia (Oreochromis niloticus) is the world’s fastest growing aquaculture species, in terms of annual increase in production (ca 10%) and is today produced world-wide. Most of the commercial and farmed Nile tilapia ... -
Optimal Contribution Selection applied to the Norwegian Cheviot Sheep population
Kjetså, Maria Henden (Master thesis, 2016-08-18)Managing inbreeding is essential for all breeding work, especially in small populations. Optimal Genetic Contribution (OCS) is a selection method that restricts inbreeding while maximizing genetic gain. The aim of this ... -
Using herd-averages of feed efficiency as training data for genomic selection
Wulijibuhe, X (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 ...
