Analysis of crosses between three strains of striped catfish (Pangasianodon hypophthalmus) in Viet Nam
(Master thesis, 2016-08-18)This study focused on harvest body weight of striped catfish (Pangasianodon hypophthalmus) in a selective breeding program in Vietnam. The first objective was to estimate additive, non-additive genetic effects and heritability ... -
Hepatic enzymes' transcription controls utilization of amino acids in Nile tilapia
(Master thesis, 2016-08-18)Nile tilapia is an attractive fish species for farming, due to its resistance to diseases and poor environmental quality. Tilapia can efficiently utilize low quality feed. Fish feed occurs approximately 40% of total farming ... -
Unicellular algae from the genus chlorella grown under various conditions : potential for use as feed
(Master thesis, 2016-08-18)Diverse morphological and physiological characteristics of microalgae are enabling their use in the production of protein, vitamins, antioxidants, drugs, immunostimulants, biofuels and food supplements. These physiological ... -
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 ... -
Responses to mirrors in domestic goats (Capra aegagrus hircus) : assessing mirror use to solve a problem and in self-recognition
(Master thesis, 2016-08-18)Mirror studies in animals have been used to test for self-recognition and instrumental use of the mirror as a tool to find an object hidden from view but visible via mirror-reflection. These abilities have been indicated ... -
Faktorer som påvirker kalvingsegenskaper hos norske kjøttferaser og krysninger
(Master thesis, 2016-08-18)I dag er det stor underdekning av norsk storfekjøtt på grunn av redusert antall melkekyr uten tilsvarende økning i ammekutallet, samtidig som etterspørselen etter storfekjøtt har økt. Spesialisert kjøttproduksjon med ammekyr ... -
Genomiske avlsverdier for kjøttproduksjonsegenskaper hos Norsk Rødt Fe
(Master thesis, 2016-08-18)Norsk Rødt Fe (NRF), som er den mest brukte rasen i Norge, har gode både melke- og kjøttproduksjonsegenskaper. Kjøttproduksjonsegenskaper er viktig egenskapsgruppe som har vært vektlagt i alvsmålet til NRF siden starten. ... -
Optimal Contribution Selection applied to the Norwegian Cheviot Sheep population
(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 ... -
The effect of the grit stone on feed passage rate in broiler chickens
(Master thesis, 2016-08-18)An experiment was carried out to test the hypothesis that feeding grit to broiler chickens would slower the passage rate of the feed throughout the digestive tract. At the same time, the effect of grit on the performance ... -
Strategi for opptrapping av kraftfôr etter kjeing for å sikre god produksjon og helse hos norske mjølkegeiter
(Master thesis, 2016-08-18)I Norge har mjølkeavdråtten hos geit økt mye i seinere tid. Etter kjeing er geiter ofte i negativ energibalanse (NEB), og fôring av kraftfôr må balanseres mellom tilførsel av nok energi, og samtidig unngå for mye mobilisering ... -
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, ... -
