Changes in tryptophan and kynurenine concentrations in pig plasma after in vivo immune activation and controlled tissue trauma
Jørgensen, Cathinka Celine (Student paper, others, 2020)The main purpose of this thesis is to describe the changes in plasma concentrations of kynurenine and tryptophan in pig plasma after an LPS - injection and a surgical procedure. Pigs are frequently exposed to stressors, ... -
DNA methylation profiles in red blood cells of adult hens correlate with their rearing conditions
Pertille, Fabio; Brantsæter, Margrethe; Nordgreen, Janicke; Coutinho, Luiz Lehmann; Janczak, Andrew M.; Jensen, Per; Guerrero-Bosagna, Carlos (Journal article; Peer reviewed, 2017) -
Does early environmental complexity influence Tyrosine hydroxylase in the chicken Hippocampus and “prefrontal” caudolateral Nidopallium?
Tahamtani, Fernanda Machado; Nordgreen, Janicke; Brantsæter, Margrethe; Østby, Gunn Charlotte; Nordquist, Rebecca; Janczak, Andrew M. (Journal article; Peer reviewed, 2016) -
Early environmental effects on laying hen development
Tahamtani, Fernanda Machado (PhD Thesis;2016:57, Doctoral thesis, 2018-05-04)Chickens are widely used by humans in both farm production and in scientific research as model organisms. In the farming industry, they total 27 billion individuals worldwide (FAO, 2013). Over 6 billion of these are laying ... -
Early life in a barren environment adversely affects spatialcognition in laying hens (Gallus gallus domesticus)
Tahamtani, Fernanda M.; Nordgreen, Janicke; Nordquist, Rebecca; Janczak, Andrew Michael (Journal article; Peer reviewed, 2015)Spatial cognition in vertebrates is adversely affected by a lack of environmental complexity during early life. However, to our knowledge, no previous studies have tested the effect of early exposure to varying degrees of ... -
Effects of a controlled immune activation on social behaviour, neurophysiology and the acute phase response in pigs
Veit, Christina Maria (PhD Thesis;2021:69, Doctoral thesis, 2021)Damaging behaviours, such as tail and ear biting, are important animal welfare challenges in commercial pig production. Poor health is a risk factor for damaging behaviours but the mechanisms behind this link remain unknown. ... -
Effects of the rearing period and the production phase on fear-related responses in adult laying hens
Brantsæter, Margrethe (PhD Thesis;2017:48, Doctoral thesis, 2017)In 2013, almost seven billion laying hens (Gallus gallus domesticus) produced eggs for human consumption (CIWF, 2013). Under commercial egg production, specialised rearing farmers keep the birds until they are nearly ... -
Exposure to increased environmental complexity during rearing reduces fearfulness and increases use of three-dimensional space in laying hens (Gallus gallus domesticus)
Brantsæter, Margrethe; Nordgreen, Janicke; Rodenburg, T. Bas; Tahamtani, Fernanda Machado; Popova, Anastasija; Janczak, Andrew M. (Journal article; Peer reviewed, 2016) -
Faecal cortisol metabolites as an indicator of adrenocortical activity in farmed silver foxes (Vulpes vulpes)
Hovland, Anne Lene; Rød, Anne Marit Slåtsveen; Eriksen, Marit Skog; Palme, Rupert; Nordgreen, Janicke; Mason, Georgia (Journal article; Peer reviewed, 2017) -
Problem behaviors in adult laying hens - identifying risk factors during rearing and egg production.
Brantsæter, Margrethe; Nordgreen, Janicke; Hansen, Tone Beate; Muri, Karianne; Nødtvedt, Ane C. W.; Moe, Randi Oppermann; Janczak, Andrew M. (Peer reviewed; Journal article, 2018) -
A Proposed Role for Pro-Inflammatory Cytokines in Damaging Behavior in Pigs
Nordgreen, Janicke; Edwards, Sandra; Boyle, Laura A.; Bolhuis, Elizabeth; Veit, Christina Maria; Sayyari, Amin; Marin, Daniela E.; Dimitrov, Ivan; Janczak, Andrew M.; Valros, Anna (Peer reviewed; Journal article, 2020)Sickness can change our mood for the worse, leaving us sad, lethargic, grumpy and less socially inclined. This mood change is part of a set of behavioral symptoms called sickness behavior and has features in common with ... -
Sick and grumpy: Changes in social behaviour after a controlled immune stimulation in group-housed gilts.
Munsterhjelm, Camilla; Nordgreen, Janicke; Aae, Frida; Heinonen, Mari; Valros, Anna; Janczak, Andrew M. (Journal article; Peer reviewed, 2018)Poor health is associated with an increased risk of tail biting outbreaks in pigs. We propose that this is because illness changes social dynamics either by changing the behaviour of the sick pig towards its penmates, the ... -
The effect of lipopolysaccharide (LPS) on inflammatory markers in blood and brain and on behavior in individually-housed pig.
Nordgreen, Janicke; Munsterhjelm, Camilla; Aae, Frida; Popova, Anastasija; Boysen, Preben; Ranheim, Birgit; Heinonen, Mari; Raszplewicz, Joanna; Piepponen, Petteri; Lervik, Andreas; Valros, Anna; Janczak, Andrew M. (Journal article; Peer reviewed, 2018) -
