A case study on the barriers and opportunities for the upscaling of short food supply chains : the perspective of stakeholders in Wallonia, Belgium.
(Master thesis, 2014-11-03)Despite an increasing interest in short food supply chains in the last years, these have failed to go beyond niche market and are mostly reaching wealthy consumers and small scale farming holdings. In our industrialized ... -
A comparison of organic grass-clover silages from primary growth and regrowth in dairy cows
(PhD Thesis;2016:24, Doctoral thesis, 2017-12-06)The annual milk yield of Norwegian organic dairy cows increased by 18% in 2013 compared to 2007 levels. The increased milk yield in this period was achieved by increased levels of concentrate feed in the diet. Given that, ... -
A genetic analysis of traits recorded by automatic milking systems - the possibiilty for a new method to evaluate temperament of dairy cows
(Master thesis, 2013-09-20)The increasing popularity of automatic milking systems beginning in Northern Europe and spreading to other parts of the world requires a re-evaluation of breeding goals for dairy cattle. Workability traits, including ... -
A multi-criteria assessment of the impact of previous land use and current management practices on the performance of oil palm on smallholders’ plots in the southern Thailand.
(Master thesis, 2023)In recent years, Southern Thailand has witnessed a surge in oil palm plantation expansion, driven primarily by smallholders who contribute over 90% of Thailand’s oil palm output. Despite their significant contribution, ... -
A quantitative genetic study on the proportion of males in tilapia
(PhD Thesis;2011:63, Doctoral thesis, 2011)Early sexual maturation is one the main constraints in Tilapia farming since early breeding causes stunted growth and large size variability. To circumvent this problem all-male populations are used commercially, and ... -
A sociological approach to crop diversification
(Master thesis, 2015-11-04)Worldwide the diversity of cultivated plant species decreased for the past decades under the influence of the fast development of farming technologies. This lack of diversity has environmental impacts including water ... -
A study on lactose intolerance and milk intake among people in Mgeta and Njombe areas, Tanzania
(Master thesis, 2014-08-13)This study was done in August, 2012 in Mgeta and Njombe rural areas of Tanzania for the purpose of assessing the prevalence of lactose intolerance and its severity in relation to milk intake so as to create awareness on ... -
A study on the genetic relationship between salmon lice resistance and disease resistance in Atlantic salmon
(Master thesis, 2012-09-20)The aim of this study is to find the genetic relations between resistance to salmon lice and resistance to other diseases. Three groups of Atlantic salmon from 279 full-sib families (offspring of 140 sires and 279 dams, ... -
A survey of free-living plant-parasitic nematodes associated with damage in carrot (Daucus carota var. sativus) fields in Norway
(Master thesis, 2017)Nematodes cause yield reduction in agriculture worldwide. In research, the main focus has been on cyst nematodes and root-knot nematodes and not so much on free-living plant-parasitic nematodes. Thus, the importance of ... -
A systems thinking approach to desirable changes in the supply chain of industrial hemp in Finland
(Master thesis, 2023)Agroecosystems are complex systems, where interactions between socio-ecological and ecological processes take place. Modern agricultural systems tend to externalize costs of production and deplete the Earth’s resources. ... -
Abscission in poinsettia, a methodology and –omics approach
(PhD Thesis;2018:39, Doctoral thesis, 2018)Plants detach organs in a highly controlled process called abscission. Leaves, flowers, seeds, fruits, berries and even roots abscise from the plant in response to pathogens or environmental and developmental stimuli. The ... -
Accumulation and depuration of geosmin and 2-methylisoborneol in Japanese seabass (Lateolabrax japonicus) fed diets containing different dietary protein and lipid levels in a recirculating aquaculture system
(Master thesis, 2021)Muddy flavour caused by microbially synthesized geosmin and 2-methylisoborneol (2-MIB) represents a quality challenge for production of fish in recirculating aquaculture systems (RAS). The current study was conducted to ... -
Accumulation of oat nutritive compounds during grain filling with an emphasis on beta-glucan
(Master thesis, 2014-07-31)The health benefits of oat cereals are linked to its high nutritional compounds, mixed-linkage (1→3)(1→4)-β-D-glucans (commonly referred to as β-glucans) in particular. This thesis was intended to focus on the accumulation ... -
Accuracy of Genome Wide EBVs : using three small breeds as reference population
(Master thesis, 2012-08-21)Accuracy of genomic breeding values (GEBVs) is largely determined by the number of animals used in training and predicting marker effect. Thus in populations with limited number of animals, there are the need to combine ... -
The accuracy of genomic prediction by singular value decomposition of the genotype matrix
(Master thesis, 2022)Increasing the order of the genotype matrix by augmenting the number of animals or genetic markers represents a computational challenge for genomic selection. The objective of this study is to evaluate the effect of the ... -
Accuracy of genomic prediction using group recordings
(Master thesis, 2022)Group records are the alternative solutions for traits that are affected by group interaction and are difficult or costly to measure on individuals. We aimed to investigate how group size, group composition, and validation ... -
Achieving equity (with)in Food Policy Councils : confronting structural racism and centering community
(Master thesis, 2019)This thesis investigated if Food Policy Councils (FPCs) are effectively democratizing and shaping a more equitable food system for all, or are they replicating the existing structural inequality embedded within the ... -
Adding far-red light to white LEDs : implications for cucumber seedling morphology, growth, and photosynthesis
(Master thesis, 2022)Far-red (FR) light (700–800 nm) affects photosynthetic efficiency and regulates shade responses, which influences plant morphology and growth. However, plant responses to FR vary widely between environmental conditions, ... -
