Genomic predictions including known QTL for reproduction traits in swine
(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 ... -
The influence of dietary n-3 fatty acid deficiency on fatty acid composition of total lipid fraction and individual phospholipid classes in erythrocytes of Atlantic salmon (Salmo salar L.)
(Master thesis, 2016)While global population and its demand for seafood are constantly on the rise, aquaculture is facing a significant challenge how to provide safe and nutritious fish when fish oil supplies are decreasing. More emphasis has ... -
Climate change resilience through enhanced reproduction and lactation performance in Malawian Zebu cattle

Discolouration of the dorsal white musculature of farmed Atlantic salmon (Salmo salar L.) in Norway, characterised by histological and transcriptional methods
(Master thesis, 2016)Focal melanisation in the white muscle of farmed Atlantic salmon (Salmo salar L.) has become a common finding in Norway. Depending on the magnitude of such changes, muscle tissue (fillets) are graded to lower quality, ... -
The effect of Laminaria hyperborea and its bioactive components on the intestinal health of Atlantic salmon
(Master thesis, 2016-11-23)The rapid expansion of the aquaculture industry is imposing an increasing demand on the available feed resources for aquafeeds, particularly fishmeal. Plant-derived ingredients have been widely investigated in recent years ... -
Påvirker fôropptak hos Niltilapia eller en forurenset algekultur Chlorella sorokiniana’s kapasitet som biofilter?
(Master thesis, 2016-11-16)Den encellede grønnalgen Chlorella sorokiniana har potensial til å erstatte konvensjonell bruk av nitrogenoksyderende bakterier i biofilter for å fjerne ammoniakk fra fiskens proteinkatabolisme i resirkulerte akvakultursystemer ... -
Fett og omega 3 til hest : kilder, potensiell virkning og bruksområde
(Master thesis, 2016-09-07)Bruk av mer fett i fôr til hest har i nyere tid blitt vanligere enn før. Fett gir en mulighet til å øke energikonsentrasjonen i fôret, og samtidig redusere inntaket av NSC, som sukker og stivelse. Mange hester er avhengig ... -
Expression of genes involved in regulation of polyunsaturated fatty acid metabolism in liver of Atlantic salmon (Salmo salar) undergoing parr-smolt transformation
(Master thesis, 2016-09-07)Purposes The primary aim of this thesis was to study if differences in nutritional and environmental factors influence the regulation of n-3 LC-PUFA synthesis in liver of Atlantic salmon (big smolts) undergoing parr-smolt ... -
Bruk av utrangeringsinformasjon for undersøkelse av risikofaktorer og arvegrad for mastitt hos Norsk Kvit Sau (NKS)
(Master thesis, 2016-09-06)Formålet med denne oppgaven var å vurdere ulike risikofaktorer som kan påvirke mastitt blant søyer i første paritet, undersøke genetisk variasjon, samt å vurdere om mastitt som utrangeringsårsak egner seg til bruk i en ... -
Effect of diet with whole wheat with and without girt stones on performance and digestive characteristic in broiler chickens
(Master thesis, 2016-09-06)An experiment was conducted to study the effect of feeding the diet with whole wheat with and without grit on broiler performance and digestive characteristics. The trial consisted of four treatments: one control and three ... -
The influence of dietary n-3 fatty acids on brain phospholipid composition in Atlantic salmon (Salmo salar)
(Master thesis, 2016-08-18)A feeding experiment was conducted to examine the percentages of different fatty acids in brain phospholipid subclasses under feeding dietary inclusion levels of EPA, DHA or a 1:1 mixture of EPA and DHA in farmed Atlantic ... -
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 ... -
Effect of inclusion zeolite as grit in commercial pelleted diet on caged broiler's growth performance, gizzard parameters and excreta size distributions
(Master thesis, 2016-08-18)The purpose of this experiment is to determine effects of inclusion zeolite as grit in modern caged broilers. A total of 252 day-old male broilers arrived in pens and were reared only commercial starter pellets and water ... -
The effects of marble grit supplementation on the performance of broiler chicken
