  1. 1. Temperature dependent preening behaviour in common guillemots Uria aalge

    Kandidat-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Saga-Savanna Kynman; [2023]
    Nyckelord :common guillemot; common murre; seabirds; Stora Karlsö; heatstress; temperature; preening; allopreening;

    Sammanfattning : As global temperature increase, new thermal conditions may challenge the physiological limits of endotherms. Examining the direct effects of extreme temperatures is an important component in understanding how these physiological limits may impact an organism’s behaviour, breeding success and survival.

  3. 2. Perch and litter preferences in chicks

    Master-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Cecilie Bramgaard Kjaersgaard Nielsen; [2018]
    Nyckelord :animal welfare; behaviour; perch preference; litter preference; poultry;

    Sammanfattning : There is a lack of research on the litter and perch preferences of chicks during the first three weeks of their lives. The purpose of this study was to identify which perch and litter types the chicks preferred, if their preference changes over time and if the preference of litter types change depending on the specific behaviours.

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

    Kandidat-uppsats, Linköpings universitet/Biologi

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

    Sammanfattning : 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. LÄS MER

  5. 4. Miljöns inverkan på slaktkycklingars beteende

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

    Författare :Aleksandra Eriksson Borovicanin; [2016]
    Nyckelord :slaktkyckling; miljöpåverkan; beteende; miljö; beläggningsgrad; ljusstyrka;

    Sammanfattning : Skillnaderna i beteende mellan den röda djungelhönan och slaktkycklingar är inte stor. Därför är det intressant att se hur slaktkycklingen påverkas av den kommersiella miljö den hålls i, en miljö som skiljer sig mycket från hur den röda djungelhönan lever. LÄS MER

  7. 5. Behavioural effects of food deprivation on red junglefowl (Gallus gallus) and White Leghorn layers

    Magister-uppsats, Institutionen för fysik, kemi och biologi

    Författare :Jenny Lind; [2007]
    Nyckelord :fowl; chicken; hunger; food deprivation; behaviour; motivation;

    Sammanfattning : The aim of this study was to examine how food deprivation effects food-related and other behavioural systems of red junglefowl (Gallus gallus) and the domesticated White Leghorn layers. If an animal is denied to perform their natural behaviours, like eating, sleeping or preening, the motivation for the behaviour can increase. LÄS MER
