  1. 1. Heritability of methane emission in Swedish Red cattle in northern Sweden

    Master-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Lucy Chipondoro; [2024]
    Nyckelord :methane emission; heritability; swedish Red cattle; dairy cow;

    Sammanfattning : Dairy cattle contribute a significant proportion of greenhouse gases (GHG), mainly methane (CH4), among other livestock species. Methane has a negative impact on climate; therefore, its reduction is a top priority for a sustainable dairy production system. LÄS MER

  3. 2. Comparing Quantum and Semi-Classical Approaches to Non-Collinear Magnetism in an Electron-Spin Dimer

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

    Författare :Sherwan Jamo Abdi; [2023]
    Nyckelord :Skyrmion Electron Spin Dzyaloshinskii-Moriya Interaction DMI Ehrenfest Semiclassical; Physics and Astronomy;

    Sammanfattning : In this bachelor thesis, an explorative theoretical analysis is presented on a model system characterized by various and competing magnetic interactions. The system comprises two localized magnetic moments (spins), and a single itinerant electron that hops between two orbitals located at the spins’ positions. LÄS MER

  4. 3. Design-Manufacturing Integration : Challenges in change management for new component in-house manufacturing

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Siet-Ling Law Hing Ping; Rahul Suresh; [2022]
    Nyckelord :Computer Aided Design CAD ; engineering drawings; cable harness; R D; production; design-manufacturing integration; collaborative product development; model based definition; Computer Aided Design CAD ; ingenjörsritningar; FoU; produktion; design-tillverkning integration; kollaborativ produktutveckling; modellbaserad utveckling;

    Sammanfattning : In the highly competitive transportation industry, one way to gain a competitive advantage is to ensure the customer needs are satisfied and tailored according to each customer’s need. Scania’s one of the core values is customers first and believes that the organization is successful only when its customers are successful. LÄS MER

  5. 4. Effects of cow-calf contact on feed intake, milk production and energy balance in dairy cows in early lactation

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Carina Tufvesson; [2021]
    Nyckelord :Cow-calf contact system; dairy cow; suckling; feed intake; feeding pattern; milk production; energy balance;

    Sammanfattning : The objective of this study was to compare the production level, feed intake and energy balance in early lactation of non-suckled cows against cows in a cow-driven cow-calf contact (CCC) system. CCC systems have become interesting to evaluate as they are thought to provide a more natural behaviour for both the cow and calf, several studies have reported higher growth and better health in calves kept in these systems.

  7. 5. Performance of dairy cows fed grass-clover silage or biorefined silage pulp of grass-clover silage

    Master-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Matilda Larsson; [2021]
    Nyckelord :biorefined silage; silage pulp; forage; milk production; dairy cow;

    Sammanfattning : Grass and legumes can do ecosystem services like no other crops and are one of the biggest contributions to protein in dairy cow diets. Biorefining of silage, makes it possible to produce a high-fibre silage pulp (SP) that can be fed to ruminants and a local high-quality protein feed (press juice) for monogastric animals. LÄS MER
