(Master thesis, 2021)This study focused on the effects of dietary inclusion of black soldier fly larvae (Hermetia illucens) fractions on extruder parameters, pellet quality, growth performance and nutrient digestibility and utilization in ... -
Effect of dietary protein and lipid sources on technical quality of pellets for Atlantic salmon
(Master thesis, 2022)The purpose of the research was to examine technical quality of pellets added protein (P) and oil (O) sources of vegetable (V) or marine (M) origin. Four different diets for Atlantic salmon smolts were produced with 1) ... -
Effect of packaging materials and storage conditions on development on tip rot in carrot
(Master thesis, 2022)Tuppråte er eit aukande problem ved lagring av norske gulrøter, og fører til mykje svinn og tap av god Gulrot er ein av dei viktigaste grønsakene dyrka i Noreg. I 2020 vart det produsert 54 000 tonn gulrot som utgjer ein ... -
The effect of processing on physical and chemical quality of pelleted feeds for ruminants
(Master thesis, 2018)This study carried out to examine the effect of feed processing on physical quality of feedstuff and on rumen degradation rate of dry matter, protein and starch. Each of three feedstuffs, barley, maize, and soybean meal ... -
Effect of short time temperature alteration on two key reproduction hormone levels of Nile tilapia (Oreochromis niloticus)
(Master thesis, 2020)This study investigates the effects of rapid and short temperature change on the levels of the hormones testosterone and estradiol-17β and the subsequent effect on egg maturation in Nile tilapia (Oreochromis niloticus). ... -
Effect of steam-conditioning and enzymatic treatment on rheological properties of the shrimp feed, formulated with torula yeast (Candida utilis) as a novel feed raw ingredient
(Master thesis, 2018)The use of yeast as an alternative source of protein has been in demand as a novel feed ingredient in shrimp feed nowadays. In order to optimize its use, more research and study is required. The objective of this study was ... -
Effect of temperature-photoperiod interaction on growth and winter bud development in Norway spruce (Picea Abies)
(Master thesis, 2020)Woody species growing in temperate and boreal regions, like Norway spruce (Picea abies) have to enter dormancy to survive winter and freezing temperatures, while simultaneously maximizing their growing period. Dormancy is ... -
Effect of using insects as a dogfood ingredient: A perspective on technology and nutrition on focus to Lumbriculus variegatus, Hermetia illucens and Tenebrio molitor- A literature review
(Master thesis, 2021)The use of insect as food and feed has been in existence for a very long time as it was used as an alternative protein source for food and feed production. The current food crises has caused researchers to find ways of ... -
Effects of Candida utilis as a protein source and replacement of soybean meal and yeast with barley on feed utilization and nitrogen use efficiency in dairy cow diets
(Master thesis, 2020)An increasing global population requires increasing sustainable food production. Today, protein from soybeans is used in concentrates to dairy cows. Climatic conditions make it difficult to grow soybeans and other protein ... -
Effects of changes in the breeding goal on genetic improvement for maternal traits in Landrace pigs
(Master thesis, 2018)Maternal ability is becoming increasingly more important in today’s breeding practices, as it increases the animal welfare, as well as, decreases the economic cost related to the loss of animals. Because of the complexity ... -
Effects of different light intensities, light spectra and temperatures on the growth and fatty acid composition of the microalgae Acutodesmus obliquus
(Master thesis, 2019)The subject of this thesis were the effects of cultivation of different light intensities, spectral light areas and temperatures on growth and fatty acid composition in the microalgae Acutodesmus obliquus. While previous ... -
Effects of extruded pellets on physical feed quality and digestion behavior in dairy cows
