Ontogeny of the cloacal gland in male Japanese quail classified in a T-maze
(Poultry Science Association, 2007-09-01)
Broiler chicks that traverse a T-maze quickly to reinstate contact with their companions (HP, high performers) are known to grow faster, are more social, and have a reduced plasma corticosterone response to acute stress ...
Cloacal gland and testes development in male Japanese quail selected for divergent adrenocortical responsiveness
(Poultry Science Association, 2004-05-01)
The time course of sexual development in male quail from lines selected for either a reduced (low stress, LS) or an exaggerated (high stress, HS) plasma corticosterone response to brief restraint was determined. Sexual ...
Photoperiod-induced changes in cloacal gland physiology and testes weight in male Japanese quail selected for divergent adrenocortical responsiveness
(Poultry Science Association, 2004-06-01)
In quail, activation of the hypothalamic-pituitary-adrenal axis has been linked to depression in the hypothalamic-pituitary-testicular axis, and cloacal gland development and foam production are known to be androgen ...
Cloacal gland growth differences in high and low plasma corticosterone stress response line male quail reared under short daylengths
(Poultry Science Association, 2007-06)
Mail quail selected (generation 32) for reduced [low stress (LS)] or exaggerated [high stress (HS)] plasma corticosterone stress response to brief mechanical restraint (5 min of immobilization) were studied for differences ...
Selection of Japanese quail for reduced adrenocortical responsiveness accelerates puberty in males
(Poultry Science Association, 2002-07-01)
Differences in the onset of puberty were assessed in male Japanese quail from a random-bred (RB, control) line and two lines that had been genetically selected for reduced (low stress, LS) or exaggerated (high stress, HS) ...
Cloacal gland, endocrine testicular, and adrenocortical photoresponsiveness in male Japanese quail exposed to short days
(Elsevier Science Inc, 2013-01)
Photoperiod is the most important “noise-free” seasonal environmental cue for synchronizing physiological states (such as reproductive activity) in birds. However, in photoperiodic birds such as Japanese quail, the effect ...
Testosterone manipulation postcastration does not alter cloacal gland growth differences in male quail selected for divergent plasma corticosterone stress response
(Poultry Science Association, 2010-12)
Japanese quail selected for reduced (low-stress, LS) rather than exaggerated (high-stress, HS) plasma corticosterone response to brief restraint have consistently shown greater cloacal gland (CG) development, an ...
Divergent cloacal gland photo-responsiveness in male Japanese quail exposed to short days and associated differences in social interactions and reproduction
(Oxford University Press, 2017-01)
Quail under short d (SD) reduce their gonadal development, and consequently their cloacal gland (CG) size, aggressiveness, sexual behaviors, and reproductive performance. However, some quail appear nonresponsive to SD ...
Evolution of the cloacal and genital musculature, and the genitalia morphology in liolemid lizards (Iguania: Liolaemidae) with remarks on their phylogenetic bearing
(Brill Academic Publishers, 2018-02)
In this study, we describe the intra-and interspecific anatomical variations of cloacal and related muscles of male and female genitalia in species of five iguanian genera (three liolemid: Ctenoblepharys, Liolaemus, and ...
Temporal dynamic of adrenocortical and gonadal photo-responsiveness in male Japanese quail exposed to short days
(Elsevier Inc, 2014-07)
The study evaluated whether different short-term endocrine testicular and adrenocortical responses to short photoperiod exposure can persist over time and particularly when birds exhibit spontaneous cloacal gland recovery. ...
