Sheep breeds in contrasting environments - pasture utilization at different spatiotemporal scales
(PhD Thesis;2018:24, Doctoral thesis, 2018)In Norway, approximately 2 million sheep are released onto outer fields for summer grazing. Indeed, during the summer months sheep are the most common large herbivores in most Norwegian mountain areas. The sheep, of which ... -
Yield and quality of vegetables fertilized with materials recycled from organic resources
(PhD Thesis;2021:64, Doctoral thesis, 2021)Agriculture, aquaculture, fishery and households generate large amounts of organic wastes with high contents of nitrogen (N) and other nutrients. Concurrently, supply of off-farm N resources into horticultural production ... -
Growth, stomatal responses and postharvest characteristics of Rosa x hybrida : the influence of air humidity and light quality
(PhD Thesis;2013:77, Doctoral thesis, 2013)Greenhouse production systems are important in the production of vegetables, herbs and ornamentals. Roses are among the most valuable crops in the greenhouse floriculture industry and are produced as pot plants or as a cut ... -
Sensitivity to gamma radiation of Scots pine seedlings grown from seeds developed under elevated levels of ionizing radiation
(Master thesis, 2021)As being sessile, plants are generally exposed to background levels of ionizing radiation in their natural environment due to cosmic radiation as well as alpha-, beta- or gamma- emitting radionuclides in naturally occurring ... -
The relevancy of stakeholder engagement in aiding the sustainable shift : an investigation through the eyes of farmers
(Master thesis, 2021)With growing awareness of the agricultural industry’s struggle to internalise and implement the sustainability shift, new methods for aiding the shift are being sought. As a growing number of findings can connect with ... -
A descriptive study of the physical quality of commercial broiler pellets across the world
(Master thesis, 2021)This thesis work intends to give a general insight into commercial broiler pellets' physical quality and discuss the differences from a scientific point of view. The samples were delivered to the Norwegian University of ... -
Dynamic dietary salmon farming in the Faroe Islands with regards to production, quality and economic improvements
(PhD Thesis;2018:104, Doctoral thesis, 2018)The development of feeds for Atlantic salmon has been an ongoing process since the industry started in the 1970s. In the early years, salmon feeds had higher share of proteins than lipids, but after the introduction of ... -
Tetradecylthioacetic acid (TTA) : a functional feed ingredient for Atlantic salmon affecting early sexual maturation, cardiac robustness and β-oxidative capacity
(PhD Thesis;2018:36, Doctoral thesis, 2018)Utilisation of fatty acids highly dominates energy metabolism in high performance fish as the Atlantic salmon. It is well established knowledge that feed intake and growth of salmon is highly influenced by water temperature ... -
Growth, feed utilization, health and biometric parameters in Atlantic salmon (Salmo salar L.) - Influence of dietary protein-to-lipid ratio and body fat status
(PhD Thesis;2018:103, Doctoral thesis, 2018)Today, commercial diets for large farmed Atlantic salmon (Salmo salar L.) commonly contain 30-35 % protein and 35-39 % lipids, i.e. a ratio of protein-to-lipids below 1. Such energy dense diets have generally been shown ... -
Genetic improvement of feed efficiency in dairy cattle
(PhD Thesis;2017:106, Doctoral thesis, 2017)The main objective of the thesis was to investigate the requirements and possibilities for including feed efficiency (FE) in the breeding goal in dairy cattle and hence enable the genetic improvement of feed efficiency. ... -
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 ... -
Policies for agroforestry and diversification of productions in Wallonia
(Master thesis, 2021)Agroecology is more and more acknowledged as one of solutions toward sustainable transitions of our food systems. Practices such as agroforestry and diversification of production are part of the strategies used within an ... -
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 ... -
Enhancing biodiversity in French crop production systems : Cost-benefits analysis on five measures from the Ecostack project
(Master thesis, 2021)A decrease of biodiversity in agricultural landscapes has been observed in the last decades. Stacking biodiversity around and inside fields would provide a method to counterbalance this effect. This study, conducted within ... -
Mapping agroecology initiatives in Austria and Germany
(Master thesis, 2021)Transforming food systems is necessary to address the global issues of severe biodiversity loss, hunger and malnutrition, as well as the consequences of the rapidly advancing climate change. Agroecology as a systemic ... -
