1. Perching behaviour and disturbance during sleep in three hybrids of broiler chicken (Gallus gallus domesticus)
Kandidat-uppsats, SLU/Dept. of Animal Environment and HealthSammanfattning : The aim of broiler chicken production is to breed chickens with high growth rate and muscle/bone ratio. However, this selection has affected the physiology of the broilers and as a result broilers display a physique that inhibits them in executing behaviours that they are motivated to perform. LÄS MER
2. Fjäderplockning hos värphöns och dess relation till beläggningsgrad i olika inhysningssystem
Kandidat-uppsats, SLU/Dept. of Biomedical Sciences and Veterinary Public HealthSammanfattning : Majoriteten av alla dödsfall hos värphöns beror på fjäderplockning med efterföljande kannibalism. Fjäderplockningsbeteendet innebär ett mycket stort problem för äggnäringen eftersom det både påverkar fåglarnas välfärd till följd av skador och stress, och dessutom ekonomiska förluster via nedsatt äggproduktion och ökat foderintag.

3. Swarm-based Area Exploration and Coverage based on Pheromones and Bird Flocks
Master-uppsats, InformationssystemSammanfattning : Swarm Intelligence (SI) is a young field of study from which solutions to complex problems have been proposed based on how some natural organisms (e.g. ants, bees and others) achieve many of their daily tasks through simple sets of interactions. This thesis proposes two models for area exploration and coverage based on SI principles. LÄS MER
