1. Investigating anticipatory behaviours in lambs
Sammanfattning : Many animals kept by humans receive cues that predict future events for example food or being let out. The interval between cue and future event may however be delayed. In the best of worlds, animals may not experience such waiting as negative and it is even suggested that the anticipation following such cues is experienced as pleasurable. LÄS MER

Sammanfattning : A successful relationship between horse and rider is a partnership based on compatibility and is often referred to as a good match. In the present thesis, ‘match’ includes the good interaction, interplay and cooperation between horse and rider as well as the related positive experience. LÄS MER
3. Tail biting and feather pecking : using genomics and ethology to explore motivational backgrounds
Sammanfattning : It is well known that abnormal animal behaviour is affected by both environment and genetics. This thesis aimed to use behavioural observations as well as gene expression measurements to explore how animals that perform and receive tail biting (pigs) and feather pecking (laying hens) differ from individuals that are not involved in these behaviours.

4. Using spatial distribution and behaviour to determine optimal space allowances for poultry and rabbits
Sammanfattning : Previous research on the effect of stocking density on welfare has focused on adverse effects on health and behaviour. Absence of such effects does not mean that space allowance is optimal from the animals’ point of view. This thesis aimed to assess optimal space allowances by studying spatial distribution and behaviour. LÄS MER
5. Never wake a sleeping broiler : An undisturbed natural resting pattern in broilers
Sammanfattning : The importance of sleep and rest for animals is well known, but rarely mentioned and considered in the handbooks for broiler production, nor when welfare issues are discussed in relation to the production settings. Resting behaviours make up a large part of the daily time budget of broilers, making the quality of rest highly important for the welfare of the birds. LÄS MER
