  1. 1. Prevalensen av rörelseasymmetrier hos föl : en jämförelse mellan ridhästföl och travhästföl

    Master-uppsats, SLU/Dept. of Anatomy, Physiology and Biochemistry

    Författare :Olivia Nordberg; [2022]
    Nyckelord :rörelseasymmetri; föl; hälta; objektiv rörelseanalys;

    Sammanfattning : Ortopediska skador är ett vanligt problem hos sporthästar, ofta med hälta som följd. Tidigare studier har observerat att hästar som anses friska av ägaren ofta har ett asymmetriskt rörelsemönster som vid en objektiv bedömning bedöms som hälta. LÄS MER

  3. 2. Association analyses of forehead hair whorls, behaviour, and chromosome regions in Standardbred Trotters

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Animal Breeding and Genetics

    Författare :Victoria Saxe; [2022]
    Nyckelord :behaviour; temperament trait; tricoglyph; hair whorl; swirl; genetics; horse; Standardbred trotter; genotype; phenotype;

    Sammanfattning : Introduction: In horse breeding, athletic skills have been in focus and certain behaviour types have been found to be important for competition. Behaviour is heritable but is also affected by the environment. Just like humans, animals have their own personality and behaviour-traits. LÄS MER

  4. 3. Exploration of the hereditary cause of sex ratio distortion in horses

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

    Författare :Susan Ott; [2021]
    Nyckelord :Sex ratio; horse; selfish genetic elements; meiotic drive; Icelandic horse; Standardbred horse; Coldblooded trotters; heritability; Trivers-Willard hypothesis; pedigree data;

    Sammanfattning : Even sex ratios are seen as evolutionarily stable and are maintained by a selection against a skewed sex ratio. However, sometimes sex ratios at birth are skewed towards one sex. Reasons for this phenomenon are often unknown. LÄS MER

  5. 4. Genetic background of temperament traits in standardbred trotters

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

    Författare :Paulina Berglund; [2021]
    Nyckelord :temperament; standardbred trotter; heritability; low-pass whole genome sequencing;

    Sammanfattning : The genetic background of temperament traits in horses has been subject for research for many years to obtain understanding of domestication, breed differences and welfare. Previous studies have found heritabilities ranging from low to moderate for temperament. LÄS MER

  7. 5. Can eye-temperature variation from exercise explain behaviour profiles among trotting horses?

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

    Författare :Paulina Berglund; [2019]
    Nyckelord :eye-temperature; horse behaviour; stress; trotting horses; harness racing; Standardbred; coldblooded trotter;

    Sammanfattning : Eye-temperature measured with infrared thermography have in previous studies showed significant correlation to competition results in harness racing. Studies also show a positive correlation between serotonin level in blood and eye-temperature which indicates that this method could serve as an indicator of stress and welfare in harness racing.
