The effect of Jersey in Norwegian dairy production
(Master thesis, 2022)Alterations in customer demands has the latest years increased the aggregate demand for milk fat from Norwegian dairy production. To encourage farmers to produce more milk fat, the premium for fat has been increased to ... -
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 ... -
Effect of Poultry hydrolysate on growth and welfare in farmed Atlantic Salmon Smolt (Salmo Salar).
(Master thesis, 2023)The objective of this study was to investigate the effects of different levels of poultry hydrolysate (PH) on the performance and welfare of 94g per Atlantic salmon smolts. Five experimental diets were fed to the fish for ... -
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 Red to Far-red ratio on assimilation, growth, and morphology of two cucumber cultivars (Cucumis sativus cv. Hi Light and Imea)
(Master thesis, 2023)The effect of different red to far-red (R:FR) ratios were studied on two cucumber cultivars; 'Hi Light' and 'Imea'. Observations were done on photosynthetic efficiency, morphological characteristics, growth and carbohydrate ... -
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 ... -
