    Master-uppsats, SLU/Dept. of Economics

    Författare :David Wästljung; [2017]
    Nyckelord :land allocation; biofuels; Rotterdam-model; indirect land use change;

    Sammanfattning : Biofuels are versatile and have a big field of use. However, biofuels produced from starch crops like cereals have been claimed to threaten food security and cause higher CO2 emissions due to other cereal producer’s expansion of their enterprises. LÄS MER

  4. 23. Milk production and protein utilization in high producing dairy cows fed a low CP diet based on cereals and roughage only : a full lactation study

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

    Författare :Susanna Räisänen; [2016]
    Nyckelord :dairy cows; lactation; milk production; protein utilization; nitrogen efficiency; dietary protein level;

    Sammanfattning : A feeding trial investigating the effect of a concentrate diet consisting only of cereals on milk production, protein utilization and nitrogen efficiency was conducted on Swedish dairy cows. 13 SRB and 12 SH cows were randomly assigned to one of two groups: group 1 was fed a concentrate feed (Cereal), mainly consisting of barley (36%), wheat (34%), oats (25%) as well as molasses (2%) and a mineral and vitamin mix (3%), whereas group 2 had access to both Cereal and a protein rich concentrate feed (Prot) based mainly on soya bean (51%) and rapeseed cake (28%).

    Författare :Adriana Llopis Palomares; [2016]
    Nyckelord :early lactation; dairy cows; low concentrate; milk production; energy balance;

    Sammanfattning : Current concerns about sustainable agriculture and the needs to reduce the use of concentrates has led researchers to investigate new approaches in feeding systems for dairy cows. The beginning of lactation is a threatening episode in cow’s life. LÄS MER

  7. 25. Reducerade fungiciddoser vid bekämpning av potatismögel - vilka blir följderna?

    Magister-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Magnus Jönsson; Gabriella Olsson; [2015]
    Nyckelord :potatisbladmögel; Phytophthora infestans; aggressivitet; fungicidtolerans; Inifinito; Ranman Top; Revus Top; potato late blight; aggressiveness; fungicide tolerance;

    Sammanfattning : Potato late blight, caused by the oomycete Phytophthora infestans, is the most devastating crop disease in potato crop globally and annually cost growers 5 billion USD in losses and control measures. Large quantities of fungicides are used for the control of potato late blight in order to avoid yield loss and to limit the risk of tuber blight. LÄS MER
