Fear response and social interactions in dairy goat housed in three different densities during pregnancy
(Master thesis, 2012-09-06)Farm animals are social and are willing to work for access to social companions. To separate and isolate animals from each other is a strong stressor, and will induce fear. The fear of novel and fear-eliciting situations ... -
Feasibility of using rare earth elements (REEs) to mark and identify escaped farmed Atlantic salmon (Salmo salar L.)
(Master thesis, 2014-02-11)The development of a marking technique which could be efficiently used to mass-mark different groups of salmonids, would be a great tool for fisheries and aquaculture management. The present study was conducted in order ... -
Feed intake, milk yield and variation in the reticulo-rumen pH with Norwegian Red dairy cows given access to concentrate feeds differing in the level of local ingredients
(Master thesis, 2023)When trying to achieve a higher degree of self-sufficiency, there is a challenge with the high starch levels in grain and the Norwegian climate, which is not particularly well adapted to the cultivation of oil crops. To ... -
Feed intake, nutrient digestibility, growth performance and general health of piglets fed increasing levels of yeast
(Master thesis, 2017)In Norway, the climatic conditions and limited agricultural area impedes production of protein-rich plant-feedstuff, leading to the current dependency of import of soybeans. Norway has large forest areas, which constitute ... -
Feed quaility for improved survival and robustness of cleaner fish
(Master thesis, 2014-02-19)The aim of study was to improve the quality of moist feed for Ballan wrasse with use of different binders and inclusion level of the binders, as well as optimizing the immersion bath to improve gelling of alginate. Quality ... -
Feed structure : effects on physical quality of the feed, chemical status of the feed and nutritional consequence
(Master thesis, 2013-10-21)Two experiments were conducted to study effects of grinding and pelleting on feed structure using either wheat or maize as a base ingredients. In experiment 1, four diets were formulated to contain either completely ground ... -
Feeding behaviour of dairy cows fed a diet with protein derived from yeast (Candida utilis) compared with diets containing soybean meal and barley
(Master thesis, 2020)Norwegian Red dairy cows (NRF) are fed mainly roughage, with supplemented concentrate feed to increase milk production. Concentrate feed contains approximately 50 % nationally sourced ingredients, while the rest are imported, ... -
Feeding East Africa : are genetically modified crops part of the solution?
(Master thesis, 2017)The African continent is faced with enormous challenges of poverty, hunger and food insecurity, which is exacerbated by climatic and environmental change, and a rapidly increasing population; and in the midst of it all is ... -
Feminist Agroecology: Perspectives from Female Farmers in Norway
(Master thesis, 2022)Agroecology is a solution to transform food systems and meet the multifold crises of climate, biodiversity loss, food insecurity and social inequality. These crises impact people differently based on gender, ethnicity, ... -
Fenologisk utvikling i rødkløver
(Master thesis, 2015-02-26)Rødkløver (Trifolium pratense) er en viktig plante i grovfôrproduksjonen i Norge. Det er nær sammenheng mellom fôrvekstenes fenologiske utviklingstrinn og deres fôrkvalitet. Både med tanke på praktisk dyrkingsveiledning ... -
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 ... -
Fettsyresammensetning i kumelk ved fôring med surfôr av timotei, raigras eller mais
(Master thesis, 2010-12-06)I denne oppgaven var hensikten å sammenligne virkning av fôring med timotei-, raigras eller maissurfôr på fettsyresammensetning i kumelk. Siden tidligere forsøk, blant annet på Jæren, med bruk av raigras har gitt gode ... -
Fiberrike ingredienser i fôr til fjørfe : effekt av bygg på produksjonsresultater for slaktekylling og erteskallfiber på energiverdi for voksne haner
(Master thesis, 2012-08-13)Det ble utført et forsøk med byggbasert fôr til slaktekyllinger. Fôret ble tildelt i to dietter der den ene var tilsatt enzym (β-glukanase og xylanase) og den andre var uten tilsetning. Det er kjent at slaktekylling ikke ... -
Field dissipation of pesticides used in Norwegian carrot production and pesticide residues in carrots in Norway compared to China, the European Union and Germany
(Master thesis, 2020)The use of pesticides has not only positive effects on yield and food safety but also poses a risk to the environment and human health. Residues of pesticides are frequently detected in food crops, water, and soil, but a ... -
Filamentous fungi (Paecilomyces variotii) as an alternative sustainable ingredient in diets for Atlantic salmon (Salmo salar) : effects on pellet quality, growth performance, nutrient digestibility and utilization, and immune-related biomarkers in the distal intestine during the freshwater phase.
(Master thesis, 2023)Filamentous fungi (FF) are promising microbial ingredients (MI) for use in aquaculture feeds due to their high protein content and bioactive components with potential health beneficial effects. This study aimed to assess ... -
Fillet quality and health of vaccinated or unvaccinated Atlantic salmon (Salmo salar L)
(Master thesis, 2015-12-14)The prime goal of the present study was to investigate the impacts of vaccine on biometric traits, melanization of tissues and fillet quality of Atlantic salmon (Salmo salar L). In the experiment, a total number of 420 ... -
