    Keywords : Bulls; breeding; SNP; traits; decades; production; health; SLB; Holstein; SRB;

    Abstract : Breeding on bulls have occurred during many decades in the same way as it has for dairy cattle. Both the sire and dams that are being used during the selection breeding have been tested through genomic selection to see their value for each trait, for the dams this has been started more recently than for the bulls.

  2. 2. Bevattning i vallodling

    University essay from SLU/Dept. of Soil and Environment

    Author : Gabriel Thor; [2020]
    Keywords : grovfoder; vattenbrist; torkstress; torka; bevattningsdamm; försommartorka;

    Abstract : Denna litteraturstudie handlar om hur bevattning påverkar vallens av-kastning. Det är ett viktigt ämne att diskutera efter den extrema sommaren 2018. Med klimatförändringarna är det troligt att säsongerna blir mera vari-erande, trots det måste grovfoderförsörjningen till våra lantbruksdjur säk-ras. READ MORE

    Keywords : Arch dam; Buttress dam; Concrete; Finite element analysis; Ice load; Valvdamm; Lamelldamm; Betong; Finit elementanalys; Islast;

    Abstract : It is essential to understand the mechanics of ice load and how it affects concrete dams located in a cold climate, such as Sweden, where the temperature becomes sufficiently cold to freeze the surface of the reservoir. The purpose of this thesis is to study ice load distribution along concrete dams, and its response during the application of an ice load. READ MORE
