“…Similar, or lower estimates have been reported for other species such as Japanese quail (h 2  0.22, mid-parent/progeny regression; Satterlee and Johnson, 1988) and turkeys (h 2  0.2 -0.4, realized; Brown and Nestor, 1973). It is interesting to speculate why the cortisol stress response in rainbow trout appears to have a high heritability.…”

“…The unselected (US), or random-bred fish, whose parents had been randomly selected from the F0 population, displayed a response to confinement which was midway between that of the HR and LR groups. In contrast, in Japanese quail selected for divergence in post-immobilization serum corticosterone levels, deviation from the random-bred controls line was more rapid in the highresponse line than the low-response line, which required several generations of selection to achieve a significant change (Satterlee and Johnson, 1988). In turkeys, significant differences in the plasma corticosterone response to cold stress between the selected lines were not observed until the second selected F2 generation (Brown and Nestor, 1973).…”

“…Modification of the stress response in domestic fowl by selective breeding has long been considered feasible (Brown, 1959). The stress responsiveness of turkeys (Meleagris gallopavo; Brown and Nestor, 1973), chickens (Gallus domesticus; Gross and Siegel, 1985) and the Japanese quail (Coturnix coturnix japonica; Satterlee and Johnson, 1988) have been modified by selective breeding strategies, with varying degrees of success. A similar approach has been considered with respect to aquacultured fish in which frequent or prolonged exposure to stressors significantly and adversely affects growth (Pickering, 1993;Pankhurst and Van Der Kraak, 1997), reproductive performance (Pickering et al, 1987a;Campbell et al, 1992Campbell et al, , 1994, the immune system (Balm, 1997) and flesh quality (Lowe et al, 1993;Sigholt et al, 1997).…”

ABSTRACTMale and female rainbow trout were segregated into high-and low-responding individuals (HR, LR) on the basis of their plasma cortisol response to a 3 h period of confinement imposed at five, monthly, intervals. Consistent divergence was obtained in the responsiveness of the two groups, although the difference between LR and HR groups was greater in female fish (56 c.f. 116 ng ml -1 ) than in males (45 c.f. 69 ng ml -1 ). Progeny groups (full-sib families) were obtained from the pairing of HR males and females and LR males and females. A third progeny group (US) was obtained by random pairing of parents which were not selected as HR or LR. Post-stress plasma cortisol levels in the progeny were first tested at 6 months after hatch and were significantly correlated with the response of the corresponding parental groups, HR>US>LR (178, 126, 81 ng ml -1 respectively). The difference in responsiveness between LR and HR groups was demonstrated in all four subsequent tests over a 12 month period. There were no significant differences in baseline plasma cortisol levels in LR and HR groups prior to confinement. During a 4h period of confinement, the differences in plasma cortisol levels between LR and HR fish were sustained throughout, indicating that the trait upon which the fish were selected was related to absolute maximum levels of circulating cortisol, not the rate of change of cortisol levels during exposure to a stressor. A moderately high heritability (h 2 ) for confinement-induced plasma cortisol of 0.41 was obtained by a parent-progeny regression. Manipulation of stressresponsiveness in fish by selective breeding offers scope for optimising performance under intensive rearing conditions but also provides a useful research tool for investigating the operation of the endocrine stress response.3

“…Pig populations show much functional variation (e.g. Foury et al, 2007)) and divergent genetic selection for the HPA axis response to various stimuli has been successful in a wide range of species: trout (confinement stress: (Fevolden et al, 1999;Pottinger and Carrick, 1999), chickens (adrenal response to ACTH: (Edens and Siegel, 1975); social stress: (Gross and Siegel, 1985), turkeys (cold stress: (Brown and Nestor, 1973), Japanese quail (immobilization stress: (Satterlee and Johnson, 1988) and mice (restraint stress: (Touma et al, 2008). The response to selection is usually very strong, with realized heritability between 0.4 and 0.5.…”

Robustness in farm animals was defined by Knap as 'the ability to combine a high production potential with resilience to stressors, allowing for unproblematic expression of a high production potential in a wide variety of environmental conditions'. The importance of robustness-related traits in breeding objectives is progressively increasing towards the production of animals with a high production level in a wide range of climatic conditions and production systems, together with a high level of animal welfare. Current strategies to increase robustness include selection for 'functional traits', such as skeletal and cardiovascular integrity, disease resistance and mortality in various stages. It is also possible to use global evaluation of sensitivity to the environment (e.g. reaction norm analysis or canalization), but these techniques are difficult to implement in practice. The hypothalamic-pituitaryadrenocortical (HPA) axis is the most important stress-responsive neuroendocrine system. Cortisol (or corticosterone) released by the adrenal cortices exerts a large range of effects on metabolism, the immune system, inflammatory processes and brain function, for example. Large individual variations have been described in the HPA axis activity with important physiopathological consequences. In terms of animal production, higher cortisol levels have negative effects on growth rate and feed efficiency and increase the fat/lean ratio of carcasses. On the contrary, cortisol has positive effects on traits related to robustness and adaptation. For instance, newborn survival was shown to be directly related to plasma cortisol levels at birth, resistance to bacteria and parasites are increased in animals selected for a higher HPA axis response to stress, and tolerance to heat stress is better in those animals that are able to mount a strong stress response. Intense selection for lean tissue growth during the last decades has concomitantly reduced cortisol production, which may be responsible for the negative effects of selection on piglet survival. One strategy to improve robustness is to select animals with higher HPA axis activity. Several sources of genetic polymorphism have been described in the HPA axis. Hormone production by the adrenal cortices under stimulation by adrenocorticotropin hormone is a major source of individual differences. Several candidate genes have been identified by genomic studies and are currently under investigation. Bioavailability of hormones as well as receptor and post-receptor mechanisms are also subject to individual variation. Integration of these different sources of genetic variability will allow the development of a model for marker-assisted selection to improve animal robustness without negative side effects on production traits.

“…It has been used in selection experiments (e.g. [6,34]), and as a model for a variety of studies in embryonic development, genetics, In linkage studies, microsatellite markers are currently used because they are highly polymorphic and codominantly inherited. However, they occur at about a 5-7-fold lower frequency in avian genomes than in mammals [30] and are thought to be biased in their distribution [30,38].…”

AFLP linkage map of the Japanese quail Coturnix japonica

-The quail is a valuable farm and laboratory animal. Yet molecular information about this species remains scarce. We present here the first genetic linkage map of the Japanese quail. This comprehensive map is based solely on amplified fragment length polymorphism (AFLP) markers. These markers were developed and genotyped in an F2 progeny from a cross between two lines of quail differing in stress reactivity. A total of 432 polymorphic AFLP markers were detected with 24 TaqI/EcoRI primer combinations. On average, 18 markers were produced per primer combination. Two hundred and fifty eight of the polymorphic markers were assigned to 39 autosomal linkage groups plus the ZW sex chromosome linkage groups. The linkage groups range from 2 to 28 markers and from 0.0 to 195.5 cM. The AFLP map covers a total length of 1516 cM, with an average genetic distance between two consecutive markers of 7.6 cM. This AFLP map can be enriched with other marker types, especially mapped chicken genes that will enable to link the maps of both species and make use of the powerful comparative mapping approach. This AFLP map of the Japanese quail already provides an efficient tool for quantitative trait loci (QTL) mapping. Japanese quail / AFLP / genetic map / linkage groups / chromosomes
