Adjusting for heterogeneity of experimental data in genetic evaluation of dry matter intake in dairy cattle
(Master thesis, 2016-08-18)Feed cost is the major cost for dairying. So, improving feed efficiency could make dairy farming economically more profitable and environmentally viable by reducing methane emission. But, measuring feed intake in dairy ... -
Breeding for disease resistance against Edwardsiella ictaluri in Mekong striped catfish (Pangasianodon hypophthalmus)
(PhD Thesis;2020:77, Doctoral thesis, 2020)Bacillary necrosis (BN) is a disease caused by Edwardsiella ictaluri (E. ictaluri) that results in severe economic losses in farming of Mekong striped catfish (Pangasianodon hypophthalmus) in Vietnam. Genetic selection ... -
Establishment of a base population for long-term genetic improvement of Nile tilapia in Ethiopia
(PhD Thesis;2019:8, Doctoral thesis, 2019)The success of genetic improvement obtained in fish breeding programs depends on the genetic diversity of the founder populations and how the base population is constructed, as they influence the genetic variation of the ... -
Genetic analysis of lifespan in Irish wolfhounds
(Master thesis, 2021)Irish Wolfhounds are an ancient and large dog breed. Their lifespan is an average of 7 years only, which is associated with their size. The genetics behind the short lifespan and the combination with different known diseases ... -
Genetic studies of Nile tilipia (Oreochromis niloticus) for farming in northern Vietnam : growth, survival and cold tolerance in different farm environments
(PhD Thesis;2010:04, Doctoral thesis, 2010)The present work explores genetic parameters for growth, survival and cold tolerance of tilapia in different farm environments in northern Vietnam. The results are important for further development of selective breeding ... -
Genetic studies on improvement of striped catfish (Pangasianodon hypophthalmus) for economically important traits
(PhD Thesis;2010:43, Doctoral thesis, 2010)The aim of this study was to find non-invasive methods for measuring fillet weight, fillet yield and fillet fat on striped catfish (Pangasianodon hypophthalmus), to examine the magnitudes of genetic variance and covariance ... -
Genome-wide association study of resistance to cardiomyopathy syndrome (CMS) in Atlantic salmon (Salmon salar L.)
(Master thesis, 2019)Cardiomyopathy syndrome (CMS) is considered as a serious viral disease in Norwegian farmed Atlantic salmon. Outbreaks of the disease occur without any observable signs and CMS primarily affects adult salmon. In 2011, piscine ... -
New activity-based fertility traits for Norwegian Red dairy cattle : definitions, heritabilities and comparison to traditional fertility traits
(Master thesis, 2019)The aim of this study was to define and calculate heritabilities for new activity-based fertility traits for Norwegian Red (NRF) dairy cattle. The traits were time from calving to first high activity episode (CFHA), first ... -
Non-additive genetic effects in Nile tilapia
(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 ...
