  1. 6. Cattle grazing on semi-natural pastures : animal behaviour and nutrition, vegetation characteristics and environmental aspects

    Författare :Maja Elisabeth Pelve; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The knowledge of the grazing behaviour of cattle on Swedish semi-natural pastures and how this relates to the nutritional quality and quantity of the vegetation is low. In a situation where farming is being intensified both nationally and globally, it is important to gain more information about semi-natural pastures and how to utilise this resource properly.

  3. 7. Good enough? Animal welfare in organic poultry production

    Författare :Lina Göransson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Outdoor access, reduced stocking densities, natural light, no beak trimming, and ‘slow-growing’ broilers provided with raised sitting areas, are some of the main features of organic poultry production intended to improve bird welfare. On-farm studies are important to increase our knowledge of animal welfare in commercial production. LÄS MER

  4. 8. Domestication Effects on the Stress Response in Chickens : Genetics, Physiology, and Behaviour

    Författare :Amir Fallahshahroudi; Per Jensen; Frank Albert; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Animal domestication; stress response; gene expression; QTL; eQTL;

    Sammanfattning : Animal domestication, the process where animals become adapted to living in proximity to humans, is associated with the alteration of multiple traits, including decreased fearfulness and stress response. With an estimated population of 50 billion, the domesticated chicken is the most populous avian species in the world. LÄS MER

  5. 9. Mating behaviour and sexual selection in non-lekking fallow deer (Dama dama)

    Författare :David Stenström; Uppsala universitet; []

    Sammanfattning : This thesis examines both behavioural and morphological traits influencing male mating success in non-lekking fallow deer (Dama dama). The thesis contains results based on behavioural observations and experimental studies made on Öland and around Uppsala, Sweden. LÄS MER

  7. 10. Attacking predators and fleeing prey : detection, escape and targeting behaviour in birds

    Författare :Ulrika Kaby; Innes Cuthill; Stockholms universitet; []
    Nyckelord :zoology; ethology; birds; animal behaviour;

    Sammanfattning : The aim of this thesis is to further our understanding of predator and prey behaviour and decision making in different attack situations. The thesis deals with escape strategies, predator detection ability and prey targeting behaviour. LÄS MER
