  1. 1. Genome wide association study of milk composition traits in Swedish Red cows

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

    Författare :Yohannes Goitom Tesfayonas; [2014]
    Nyckelord :Milk composition; single nucleotide polymorphism SNP ; GWAS;

    Sammanfattning : The aim of this study was to detect QTLs that affect milk composition traits such as fat yield, fat percent, citric acid, free fatty acids as well as milk properties like fat globule size, and determine the phenotypic variation explained by the QTLs. These traits play a crucial role in nutritional and technological properties of milk and its products. LÄS MER

  3. 2. Analysis of oil content in the transgenic lines and wild-type of Lepidium campestre

    Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Philip Berg; [2014]
    Nyckelord :Lepidium campestre; Oljeanalys; Gaskromathografi; Vitrioscilla; Hemoglobingen;

    Sammanfattning : The world's population is increasing and will be reaching up to 9 billion by 2050. More food needs to be produced in order to satisfy the growing demand in the future. Meanwhile there are increased focuses on the food we produce, which are healthier and have less negative impact on the environment. LÄS MER

  4. 3. Fine mapping of resistance against root aphids in sugar beet

    Master-uppsats, SLU/Plant Breeding and Biotechnology (until 121231)

    Författare :Emma Leijman; [2011]
    Nyckelord :Resistance; Sequencing; Mapping; Molecular marker; Single-nucleotide polymorphism; SNP; Genome sequence; Breeding; Root aphids; Pemphigus betae; Sugar beet;

    Sammanfattning : Sugar beet, Beta vulgaris, is an important crop for the global sugar industry being one of the two major crops cultivated for sugar production. In the USA, the sugar beet root aphid, Pemphigus betae, is a regionally occurring pest which damages sugar beets by feeding on their secondary roots which results in reduced biomass and hence a lower yield.

  5. 4. Avel för bättre kalvningsegenskaper hos mjölkkor

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

    Författare :Emma Lövenhamn; [2010]
    Nyckelord :kalvningsegenskaper; dödföddhet; mjölkko; incidens; marker-assisted selection; genomisk selektion;

    Sammanfattning : Kalvningssvårigheter och dödföddhet är problem som finns hos svenska mjölkkor och som ökat under de senaste åren, speciellt bland förstagångskalvare. Problemen försämrar kornas välfärd och kostar pengar för bonden. LÄS MER

  7. 5. Possibilities to breed for internal parasite resistance in Swedish beef breeds

    L3-uppsats, SLU/Dept. of Animal Breeding and Genetics

    Författare :Jenny Ahlqvist; [2008]
    Nyckelord :animal breeding; cattle; parasite resistance;

    Sammanfattning : The aim of this review is to investigate the possibilities to breed for parasite resistance in the Swedish purebred beef population, with starting point in the organic production. The present population structure, breeding objectives and genetic evaluation will be discussed as well as four common internal parasites found among cattle in Sweden, registration of resistance by using faecal worm egg counts (FEC), the genetic background of FEC, and last the possibilities of using quantitative trait loci (QTL) and marker-assisted selection (MAS).
