  1. 6. Anpassningsförmåga till klimatförändringar hos kor

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

    Författare :Stina Emriksson; [2019]
    Nyckelord :anpassningsförmåga; klimatförändringar; värmestress; värmetolerans; Bos indicus; Bos taurus;

    Sammanfattning : Syftet med litteraturstudien är att undersöka skillnaderna mellan kons underarter och se vad det finns för åtgärder för att anpassa dem för framtida klimatförändringar. I dagsläget bedöms klimatförändringarna leda till högre temperaturer globalt som kan resultera i värmestressade kor. LÄS MER

  3. 7. Job-Scheduling for automated Car Parking Systems : A Machine Learning Approach

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Jan Lödige; [2018]
    Nyckelord :;

    Sammanfattning : The ever growing amount of cars and their requirement for parking space has led to the development of highly sophisticated public automated car parking systems. The user acceptance criteria for such systems is the car drop-off and retrieval time. LÄS MER

  4. 8. Calving ease and stillbirth in dairy herds using beef and dairy breed bulls

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

    Författare :Patricia Gullstrand; [2017]
    Nyckelord :crossbreeding; dairy; beef; calving ease; stillbirth;

    Sammanfattning : The aim of this study was to evaluate the effect of different sire breeds on calving traits when used in dairy herds. Records from 1,423,851 calvings from 1990-2016 were collected from the Swedish milk recording scheme from Swedish Holstein, Red dairy cattle, Hereford, Charolais, Aberdeen Angus, Limousin and Simmental sires mated with Swedish Holstein, Red dairy cattle or crossbred dams.

    Nyckelord :Typha latifolia; common cattail; SSR-marker; genetic diversity;

    Sammanfattning : Typha latifolia and T. angustifolia are wide spread perennial aquatic plants that have long history of being used by humans as a food source (rich in starch) and for raw material but they are not used much today. LÄS MER

  7. 10. Case study: phenotypic and economic effect of crossbreeding in a Swedish red and white dairy cattle herd
