Effects of Acute Tryptophan Depletion on Repetitive Behavior in Laying Hens
TLDR
In conclusion, ATD impacted the hens' social behavior by increasing the number of repetitive gentle feather pecks at conspecifics, suggesting a role for the serotonergic system on cognition in these birds.
Analysis of the brain transcriptome in lines of laying hens divergently selected for feather pecking
TLDR
A model in which the gut microbiota modulates the immune system, which in turn affects cholinergic signaling is proposed, which might have an influence on monoamine signaling with possible involvement of GABA or glutamate signaling.
The Role of Tryptophan-Kynurenine in Feather Pecking in Domestic Chicken Lines
TLDR
The effect of social disruption stress on FP and the metabolism of the amino acids TRP, phenylalanine (PHE), tyrosine (TYR), their relevant ratios, and on large neutral amino acids which are competitors with regard to their transport across the blood-brain barriers in adolescent birds selected for and against FP behavior is determined.

The control of feather pecking by serotonin.
TLDR
S-15535, a somatodendritic 5-HT-sub(1A) autoreceptor agonist, was demonstrated to be an excellent tool for reducing5-HT turnover in the forebrain of LFP and HFP chicks, and the most effective dose significantly increased severe feather-pecking behavior.
Variation in neighbouring genes of the dopaminergic and serotonergic systems affects feather pecking behaviour of laying hens.
TLDR
The annotated DRD4 in the chicken genome and re-sequenced it in 140 animals belonging to: experimental layer lines divergently selected for high and low propensity to feather pecking; the unselected founder population; and two commercial lines with low and high propensity to feathers pecking.
Chicks from a high and low feather pecking line of laying hens differ in apomorphine sensitivity
Effects of genetic origin and social environment on behavioral response to manual restraint and monoamine functioning in laying hens.
TLDR
Investigation of the effects of genetic origin, but not social environment, affected the behavioral response to manual restraint and monoamine functioning in laying hens found the WL birds struggled less during restraint and had higher dopamine and 5-HT turnover levels after restraint than did RIR birds.
