(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 ... -
Kornkvalitet i tre norske havresorter – og sortenes egnethet for havregrynproduksjon
(Master thesis, 2020)Havre er en god kilde til viktige næringsstoffer som karbohydrater, fiber (β-glukan), proteiner og fett. Proteinene har en gunstig aminosyresammensetning, og i kombinasjon med belgvekster vil havre kunne gi produkter med ... -
Effekt av SmartCalfCare systemet på separasjonsadferd hos ku og kalv
(Master thesis, 2020)I den siste tiden har det blitt større fokus på dyrevelferd i husdyrproduksjon blant både bonden, industrien og forbrukeren, og det er skille mellom hva bonden og forbrukeren ser på som god dyrevelferd. I denne oppgaven ... -
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). ... -
A holistic view of Maraîchage sur Sol Vivant : participatory action research with a group of market gardeners in France
