Unraveling the genetic mysteries of the Norwegian Fjord-horse : identifying harmful haplotypes for improved breeding strategies
(Master thesis, 2023)Fertiliteten til avlsdyrene er særdeles kritisk i små populasjoner med høy innavl. Fjordhest-populasjonen i Norge består av få stamfedre, og er blitt registrert til å ha en lavere føllings-rate enn flere andre hesteraser. ... -
Using herd-averages of feed efficiency as training data for genomic selection
(Master thesis, 2021)Genomic selection on feed efficiency traits in dairy cows can save more feed costs and result in more sustainable dairy industry. Here we estimate the accuracy of genomic selection regarding dry matter intake in dairy ... -
Vektnedgang i smolt av Atlanterhavslaks (Salmo salar) - fra ferskvann til saltvann
(Master thesis, 2021)Atlanterhavslaksen er en anadrom fisk, som vil si at den vandrer mellom ferskvann og saltvann i forskjellige stadier i livet. Oppdrettslaksen blir flyttet fra ferskvann til saltvann når den går fra parr-stadiet til smolt. ... -
Velferd på slaktegris : effekt av sosiale faktorer og fôringssystem
(Master thesis, 2020)Formålet med dette studiet var å undersøke hvor stor grad velferdsparametere påvirkes av dyretetthet, gruppestørrelse, bingedesign og fôringssystem. På grunn av økt fokus på dyrevelferd både hos forbrukere og autoriteter ... -
Vespa velutina predation impacts on Apis mellifera colony dynamics and reserves
(Master thesis, 2020)The honeybees play key environmental and economical roles as they contribute to the biodiversity preservation and to food production, through pollination. Nevertheless, Apis mellifera foragers are currently threatened by ... -
Weed invasion in different species compositions with and without perennial ryegrass
(Master thesis, 2018)Though perennial ryegrass (Lolium perenne) is a desired species in roughage production because of its nutritive qualities, it is not very persistent and - when used in species mixtures - often disappears after the first ... -
Welfare of Finishing Pigs - Effect of Decreased Stocking Density on Animal Welfare and Production Variables
(Master thesis, 2022)Modern pig farms are developed to be as economical and as efficient as possible, which has led to intensive livestock production systems. In recent years, both consumers and politicians have shown an increased interest in ... -
The welfare of finishing pigs : effects of air quality, environmental enrichment, and management
(Master thesis, 2020)It is highly important and necessary to document finishing pigs’ welfare, as healthy and happy pigs, with the ability to express their natural behaviour, will give good quality products to the consumers. A welfare ... -
What keeps dry petfood together? Optimizing homogeneity, extrusion melt and dehydration for best physical quality of petfood.
(Master thesis, 2021)Extrusion is the most common method for producing dry pet food. This technology involves various operations such as mixing, heating, kneading, shearing, and shaping. Obtaining extremely homogenous mixes of the ingredients ... -
When does the cat roam : temporal patterns of pet cat (Felis catus) roaming in Norway
(Master thesis, 2020)The domestic cats (felis catus) are popular pet animals, and their population is growing worldwide. As a natural predator, cats roaming outside raise conservation concerns. It is thereby important to know when and where ... -
Which is the future for ICTs-based services in agricultural extension in India?
(Master thesis, 2017)This report aims to deliver a state-of-the-art of new opportunities in information dissemination in rural India. Today, agricultural information transfer mechanisms are mostly generated by the public agricultural extension ... -
Whole genome sequencing with Oxford Nanopore and de novo genome assemblies of lipid-producing fungi in phylum Mucoromycota
(Master thesis, 2020)Phylum Mucoromycota consists of economically and ecologically important fungi, including industrial producers of lipids, enzymes and fermented foods and beverages, symbionts and decomposers of plants, as well as fungi ... -
Yield prediction in ryegrass with UAV-based RGB and multispectral imaging
(Master thesis, 2023)Forage grass breeding is time-consuming and costly, with the need for special knowledge and experience to make the right decisions for future forage grass production. All measurements for decision-making require manual ...
