  1. 1. Linear assessment in Swedish Warmblood foals : and the relationship to linear traits described at Young Horse Test

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Katarina Karlsson; [2020]
    Keywords : foal; breeding; genetic correlation; heritability; SWB; young horse test; foal inspection; gaits; conformation; linear traits; linear profiling; animal model; sport horse; warmblood; horse;

    Abstract : Of all Swedish Warmblood (SWB) foals born between 2014 and 2018 approximately 24% attended foal inspection. At the foal inspections trained judges assess conformation and gait traits by evaluating/subjective scoring five traits and making a linear profiling/description of 15 traits. READ MORE

  3. 2. Phenotypic differences between plus-tree progenies of Sitka spruce (Picea sitchensis) and a comparison with Norway spruce (Picea abies)

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Teresa López-Andújar Fustel; [2019]
    Keywords : Picea sitchensis; growth; heritability; phenotypic and genetic correlations;

    Abstract : Forest productivity and economic gains are two of the most important aspects to consider when managing forests these days. The performance of these depends on rotation periods and yields providing new opportunities to maximize earnings from the forest site and plant material. READ MORE

  4. 3. Variation in tameness among red junglefowls (Gallus gallus) induces variation in activity related behaviours : Exploring the basis of early domestication

    University essay from Linköpings universitet/Biologi

    Author : Ida Sörensen; [2016]
    Keywords : activity; behaviour; comfort; domestication; exploration; Gallus gallus; preening; tameness;

    Abstract : The mechanisms behind early domestication of animals are still unknown and an important question is how the changes leading to what is called the domesticated phenotype have developed. It has been suggested that the domestication process has been based on tameness of animals, and that tameness is genetically correlated to other traits. READ MORE

  5. 4. Genetiskt motstånd mot gastrointestinala parasiter och Haemonchus contortus hos får
