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 ... -
Abscission in poinsettia, a methodology and –omics approach
(PhD Thesis;2018:39, Doctoral thesis, 2018)Plants detach organs in a highly controlled process called abscission. Leaves, flowers, seeds, fruits, berries and even roots abscise from the plant in response to pathogens or environmental and developmental stimuli. The ... -
Rearing of Norwegian Red replacement heifers : effect of growth rates on lifetime production and profitability
(PhD thesis;2018:62, Doctoral thesis, 2018)This thesis is part of a larger research project aimed at assessing the impact of calf and youngstock development on dairy cow production and profitability. The rearing of Norwegian Red replacement heifers is largely ... -
Sugarcane production in Malawi : pest, pesticides and potential for biological control
(PhD Thesis;2018:65, Doctoral thesis, 2018)Sugarcane is an importance source of energy and livelihoods worldwide. The production of sugarcane is significantly affected by several insects, weeds and pathogens commonly referred to as pests. In addition, climate ... -
Identification of sperm parameters and gene variants influencing boar fertility
(PhD Thesis;2018:37, Doctoral thesis, 2018)Boar fertility has a major impact on overall pig reproductive efficiency, and good semen quality is essential for successful fertilization and proper embryo development. Thus finding semen characteristics that can predict ... -
Rapeseed co-products in pig diets : effects on nutrient and energy digestibility and metabolism
(PhD Thesis;2017:90, Doctoral thesis, 2017)The European pig industry is heavily dependent on imported protein feedstuffs, particularly soybean meal (SBM). Increased and more efficient use of locally produced protein sources, such as rapeseed (RS), could alleviate ... -

(PhD Thesis;2017:72, Doctoral thesis, 2017)Animal personality is defined by consistent between-individual differences in behaviour through time or across contexts. Behaviour is further organised into broader behavioural dimensions referred to as personality traits ... -
Characterization of genes and gene products influencing carotenoid metabolism in Atlantic salmon
(PhD Thesis;2017:36, Doctoral thesis, 2017)Distinct red flesh color is a unique trait of the fish genera Oncorhynchus, Salvelinus, Salmo and Parahucho. In this thesis we have investigated its molecular basis in Atlantic salmon to better understand how and why it ...
