1. 1. How does hatchery stress affect the development of play behavior?

   Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

   Författare :Gabrielle Lundén; [2022]
   Nyckelord :Animal behavior; Animal welfare; Gallus domesticus; Hatchery stress; Play behavior;

   Sammanfattning : Play is a behavior mainly observed in young individuals that can differ greatly between species in both function and appearance. Presence of play indicates positive experiences in animals, making play a useful assessment tool for animal welfare. Commercial hatcheries expose chicks to several stressors that can affect both behavior and welfare. LÄS MER

3. 2. The relationship between corticosterone and personality in red junglefowl

   Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

   Författare :Linnéa Lindroth; [2020]
   Nyckelord :coping styles; corticosterone; Gallus gallus; proactive; reactive; red junglefowl; stress;

   Sammanfattning : Stress cannot be fully avoided in an animal´s life, and the way that animals handle stress can be crucial for their health. Coping styles in animals are describing consistent sets of behaviour and physiological stress responses. LÄS MER

4. 3. Stress and meat quality in two lines of the Yorkshire pig breed: Swedish and Dutch

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

   Författare :Andreas Andersson; [2019]
   Nyckelord :Swedish Yorkshire; Dutch Yorkshire; stress; meat quality; behaviour test; novel Arena test; startle test; lactate; temperature and pH;

   Sammanfattning : Pigs are exposed to several different environmental stressors in the modern production from weaning, mixing, crowding etc. Preslaughter stressors may result in meat quality problems, such as the formation of pale, soft and exudative meat as well as the formation of dark, firm and dry meat, which makes the meat to be unattractive.

5. 4. Meerkats (Suricata suricatta) are able to detect hidden food using olfactory cues

   Master-uppsats, Linköpings universitet/Biologi

   Författare :Ida Sörensen; [2018]
   Nyckelord :Buried food test; food odour; foraging; meerkat; olfaction; Suricata suricatta;

   Sammanfattning : Meerkats are known to strongly rely on chemical communication in social contexts. However, little is known about their use of the sense of smell in food detection and selection. LÄS MER

7. 5. Is personality dependent of growth rate in red junglefowl (Gallus gallus)?

   Kandidat-uppsats, Institutionen för fysik, kemi och biologi; Tekniska högskolan

   Författare :Andreas Calais; [2013]
   Nyckelord :Behaviour; Chicken; Growth rate; Life-history traits; Personality; Red junglefowl;

   Sammanfattning : Personality has been reported in a large variety of animal species, but it is not obvious why animals have personality. Variation in physiological traits, such as growth rate, should theoretically affect variation in behaviours and thus can explain why we observe variation in personalities. LÄS MER
