“…Previously, it has been shown that two strains of laying hens that differ in their propensity to feather peck [6,7] also show differences in open-field reactions [19], social motivation [19] and behavioral and physiological stress responsivity [26,28]. More specifically, it was shown that in response to acute stress induced by manual restraint, adult birds of the high feather-pecking line (HFP) displayed more struggling behavior, lower heart rate variability, higher plasma noradrenaline and lower plasma corticosterone levels than birds of the low feather-pecking line (LFP).…”

AbstractFeather pecking in domestic fowl is a behavioral abnormality that consists of mild or injurious pecking at feathers of conspecifics. Previously, it was shown that chicks from a high feather-pecking (HFP) and low feather-pecking (LFP) line of laying hens already differ in their propensity to feather peck at 14 and 28 days of age. As a first step in investigating a possible relationship between the development of feather pecking and physiological and neurobiological characteristics of laying hens, two subsequent experiments were carried out. Firstly, we investigated the development of adrenocortical (re)activity in HFP and LFP chicks during the first 8 weeks of life. Secondly, we studied dopamine (DA) and serotonin (5-HT) turnover in the brain of 28-day-old HFP and LFP chicks. In both experiments, chicks were exposed to manual restraint (placing the chicks on its side for 5 min). Plasma corticosterone levels were lower (baseline on Days 3 and 56; restraintinduced on Days 3, 14 and 28) in HFP chicks. Both brain DA and 5-HT turnover were lower in the HFP chicks, as well. Possible consequences for the observed differences in (stress) physiology and neurobiology between the two lines in relation to the feather pecking are discussed. D

“…Receivers (type RLA2000, Data Sciences) were connected to a multiplexer (RMX10, Data Sciences) adapted for simultaneous data acquisition with LabPro analysis software (Version 3.1; Data Sciences) and CARDIA software (Electronic Department, Biological Centre, University of Groningen, The Netherlands). The signal was simultaneously routed from the multiplexer via a matrix (BCM100, Data Sciences) to a personal computer containing the LabPro analysis software and to a personal computer containing the CARDIA software package for real-time acquisition of heart rate and behaviour and R-R interval analysis (Korte et al 1999, Sgoifo et al 1997.

. 2000. Effects of social stress on heart rate and heart rate variability in growing pigs. Can. J. Anim. Sci. 80: 273-280. The effects of social stress on heart rate, heart rate variability and the occurrence of cardiac arrhythmias were studied in 12 growing pigs. Social stress was induced during a good competition test with a pen mate, and subsequently during a resident-intruder test with an unacquainted pig in which the experimental pig was the intruder. The outcome of a test was determined using observations of agonistic behaviour. Five pigs won the food competition test. All pigs were defeated in the resident-intruder test with an unacquainted pig. For all pigs, heart rate was significantly higher and thus the R-R interval significantly lower during the food competition test and resident-intruder test than during baseline recordings. However, pigs that were first defeated in the food competition test had a higher heart rate during the first 7 min of the resident-intruder test than winners of the food competition test. Parameters of heart rate variabiality did not significantly change during the food competition test and the resident-intruder test relative to baseline recordings. Thus, the parasympathetic and the sympathetic nervous system remained in balance during the social stress situations. This may explain why the occurrence of cardiac arrhythmias did not increase during the food competition test and the resident-intruder test relative to baseline. We showed that social status, based on agonistic encounters during the food competition test, may influence the heart rate responses of pigs during the resident-intruder test. When heart rate is used as an index of stress, results indicate that subordinate pigs may experience more stress during an agonistic encounter with an unacquainted pig than dominant pigs.Key words: Behaviour, heart rate, social stress, telemetry, pigs de Jong, I.

Le stress social en question était provoqué durant un test de concurrence pour la nourriture avec un compagnon de case habituel et ensuite durant un test de confrontation entre compagnons de case et un porc étranger, test dans lequel l'animal expérimental était l'intrus. L'issue du test était déterminée d'après observation des comportements agonistes. Cinq porcs emportaient la lutte dans le test de concurrence pour la nourriture et tous les porcs logés en groupe étaient battus dans le test de confrontation avec le porc étranger. Chez tous les porcs, le rythme cardiaque était significativement plus élevé et par conséquent, l'intervalle RR était significativement plus court dans les deux tests de concurrence et de confrontation que durant les enr...

A growing amount of data shows that a preference for passive-nonaggressive over active-aggressive problem solving is associated with higher levels of glucocorticoids (GC). For mantled howlers, the arrival of an adult male in a new group is a potential source of psychological stress for both resident males and females. Resident mantled howler males take an active stand and aggressively repel the entrance of solitary males, while females take a passive-nonaggressive stand. In order to study whether the relationship between coping strategies and the activation of the hypothalamic-pituitary-adrenal (HPA) axis observed in other species applies to the response of resident mantled howlers to the presence of solitary males, we examine the relationship between different group and subpopulation variables and the GC levels measured in feces collected from 10 groups living in six forest fragments, in Los Tuxtlas, Mexico. The results of our study suggest that the resident mantled howler females' passive response to the presence of solitary males is accompanied by the activation of the HPA axis, whereas resident males' aggressive response is not accompanied by any changes in the HPA axis. In contrast, a previous study suggests that resident male howlers respond by increasing their testosterone levels to the presence of solitary males (Cristobal-Azkarate et al., Hormones and Behavior 2006;49 261-267). These different behavioral and hormonal responses coincide with the active and passive coping styles described for other species. The conditions in which howlers live in our study area may be favoring the interaction between solitary and resident howlers, and inducing chronically high GC levels, which in turn could negatively affect the fitness of these subpopulations.
