  1. 1. 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.

  2. 2. 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

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

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

  4. 4. Traits and behaviour affecting social status in red junglefowl (Gallus gallus) hens

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

    Författare :Emelie Lindblom; [2012]
    Nyckelord :Bird; Dominance; Aggression; Exploration; Morphology;

    Sammanfattning : Social status is commonly established among individuals within groups of animals. Despite this common characteristic of social animals it is still unclear how individuals establish their status. I investigated the relationships between morphology, posture and behaviours with social status in red junglefowl hens. LÄS MER

  5. 5. Tail posture and motion as a possible indicator of emotional state in pigs

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

    Författare :Jordy Groffen; [2012]
    Nyckelord :tail posture; emotional state; pigs; novel environment test; tail condition score;

    Sammanfattning : In the current study, the aim was to investigate whether tail posture and motion can be an indicator of the emotional state of pigs and if the tail posture of the pig is affected by social breeding value (SBV), coping style and/or housing. Emotional state can be defined in two dimensions: valence and arousal. LÄS MER
