  1. 1. Factors affecting fatty acid composition in forage and milk

    Författare :Katarina Arvidsson Segerkvist; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The aims of the studies underlying this thesis were to evaluate variations in fatty acid (FA) contents of plants used as forage for dairy cows in northern Sweden, and their effects on the FA contents of the milk. Initially, samples of timothy (Phleum pratense L.) were subjected to different pre-treatments prior to analysis. LÄS MER

  3. 2. Endophytic fungi in meadow fescue and other forage grasses

    Författare :Anja Bylin; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Many cool-season forage grasses associate with an endophytic fungus of the genus Epichloë. In Sweden one of the most important forage grasses is meadow fescue (Festuca pratensis Huds.), which is known to associate with Epichloë uncinata, previously named Neotyphodium uncinatum. LÄS MER

  4. 3. Phytoestrogens and fatty acids in forage and bovine milk

    Författare :Annika Höjer; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The overall aims of the studies underlying this thesis were to investigate effects of key factors on the concentrations and composition of phytoestrogens and fatty acids in forage species, and effects of differences in their concentrations and composition in forage on their concentrations in bovine milk. In each of the spring cuts, the total isoflavone concentrations in red clover were higher at Umeå than at Skara. LÄS MER

  5. 4. Nutrient supply to reed canary grass as a bioenergy crop : intercropping and fertilization with ash or sewage sludge

    Författare :Eva Lindvall; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Production of renewable energy from herbaceous crops on agricultural land is of great interest since fossil fuels need to be replaced with sustainable energy sources. Reed canary grass (RCG), Phalaris arundinacea L. is an interesting species for this purpose. LÄS MER

  7. 5. Nutrient supply to reed canary grass as a bioenergy crop : intercropping with legumes and fertilisation strategies for phosphorus and potassium

    Författare :Eva Lindvall; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Growing energy demand and global warming are promoting research into potential new sources of renewable energy. Fossil fuels need to be replaced with sustainable energy sources to decrease emissions of greenhouse gases. Production of bioenergy from herbaceous crops on agricultural land is one alternative.
