Sammenligning av in vitro og in vivo fordøyelighet av surfôr hos drøvtyggere
(Master thesis, 2020)Det finnes ulike måter å undersøke fordøyelighet hos drøvtyggere. In vivo fordøyelighet måler fordøyelighet i levende dyr og anses som referansemetode ved fordøyelighetsforsøk. Metoden måler hvor mye av næringsstoffene som ... -
Sein bekjemping for å hindre produksjon av spiredyktige frø av hønsehirse (Echinochloa crus-galli (L.) P. Beauv.)
(Master thesis, 2020)Hønsehirse (Echinochloa crus-galli) som ofte blir ofte omtalt som verdens tredje verste ugras, sprer seg i områdene rundt Oslofjorden. Hønsehirse blir sett på som et økende problem i norsk landbruk. Artens suksess som ugras ... -
Simulating Future Climate Scenarios: The Effect on Nitrogen Utilization in Organic Fertilizers on Carrot Crops
(Master thesis, 2021)The anthropogenic addition of reactive nitrogen (Nr) to the biosphere has increased ten-fold in the last century affecting both the nitrogen (N) cycle, and indirectly, the carbon cycle. From the agriculture sector, over ... -
Small dogs display more aggressive behaviour than large dogs in social media videos
(Master thesis, 2019)Due to potentially greater vulnerability to accidents and attacks, the behaviour of small dogs may reflect greater threat sensitivity and need for protection than that of large dogs. Based on this hypothesis, I predicted ... -
Social farming in France : therapeutic benefits and sustainability of social farms
(Master thesis, 2021)Social farming is a concept that uses agricultural activities for social or therapeutic purposes. Social farms may benefit various target groups such as: young persons experiencing difficulties, the elderly, disabled people, ... -
Socio-Ecological Resilience in a Southern California Dryland Agroecosystem: Contributions from General and Specified Resilience
(Master thesis, 2021)In general, California agroecosystems are vulnerable to social and environmental change, threatening the provision of vital ecosystem services and human food security. Socio-ecological resilience, comprised of general ... -
Study of the soil macrofauna in tropical cacao-based agroforestry systems in the Dominican Republic
(Master thesis, 2021)Diversified tropical cacao-based agroforestry systems are part of the agroecological movement aiming, inter alia, at creating food systems that do not undermine the ecosystem services. However, the temporal and intra-system ... -
A study of two adipose tissue depots in Atlantic salmon : with specific focus on comparing the morphological and transcriptome characteristics between visceral and subcutaneous adipocytes
(Master thesis, 2021)Adipocytes are found in different adipose tissue depots, mainly around abdominal organs (visceral adipose tissue), or under the skin (subcutaneous adipose tissue) and between muscle fibers in myosepta including belly flap. ... -
The suitability of "the Tool for Agroecology Performance Evaluation" in a European context
(Master thesis, 2021)Agroecology is increasingly being considered to address sustainability issues in current agricultural systems. In order to assess the impacts of this new approach, FAO has developed the Tool for Agroecology Performance ... -
Survey report on the potential of establishing tilapia farm in Ivory Coast
(Master thesis, 2017-12)This report was made during a 7 month survey on the potential of establishing tilapia farm in Ivory Coast. The aim of the report is to be a source of information on the technical and social aspects of establishing a tilapia ... -
Susceptibility of different apple cultivars to European canker
(Master thesis, 2021)European canker, caused by Neonectria ditissima, is a severe economic problem for apple producers in northern Europe. The fungus can cause dieback in mature and young trees. Apple cultivars vary in their level of susceptibility ... -
The temporal expression pattern of MND1 and key regulators of floral transition in annual and perennial Pooideae species
(Master thesis, 2021)The molecular mechanisms underlying differences in annual and perennial life-history strategies are poorly understood. However, studies have shown that perennials often exhibit delayed flowering compared to related annuals. ... -
The domestication of Oreochromis mossambicus in a breeding program in Mozambique
(Master thesis, 2018)This study describes the establishment of a baseline and a base camp for the development of a genetic enhancement program for the Mozambique tilapia, Oreochromis mossambicus, with the scope of utilising both additive and ... -
The effect of tetradecylthioacetic acid (TTA) on body weight management in growing silver foxes (vulpes vulpes) as a model for dogs (Canis familiaris)
(Master thesis, 2018)This thesis consists of two parts, one general part concerning obesity and obesity related health problems in dogs. In addition, the general part gives an overview of methods to prevent obesity with restricted energy intake, ... -
The effects of environmental enrichments, group size and confinement length on play behaviour in juvenile Norwegian dairy goats (Capra hircus)
(Master thesis, 2018)Lek blir ofte betraktet som en indikator på god velferd i unge pattedyr siden det sjelden forekommer under vanskelige forhold. Det vil derfor være nyttig å vite hvordan endringer i noen normale produksjonsforhold påvirker ... -
The role of age in the selection of police patrol dogs using a standardized behavior test
(Master thesis, 2019)Police patrol dogs face many challenging situations, and only a proportion of dogs are suitable for this work. It is desirable to identify suitable dogs as early as possible, allowing unsuited dogs to be released for other ... -
