| eyes have a role in photoperiodic control of sexual activity of coturnix. | in blinded japanese quail (coturnix coturnix japonica) encephalic photoreception of the stimulus from long photoperiods is sufficient to induce and maintain normal gonadal function in females (egg laying) and in males (enlargement of the cloacal gland). however, the termination of sexual activity by short days is dependent on these birds having experienced long days at the time of blinding. | 1972 | 17815368 |

| origin of hemopoietic stem cells in embryonic bursa of fabricius and bone marrow studied through interspecific chimeras. | the histogenesis of the bursa of fabricius and of bone marrow was studied by a biological cell marking technique based on differences in the nuclear structure of two species of birds, japanese quail (coturnix coturnix japonica) and chick (gallus gallus). in quail cells the nucleus contains a large amount of heterochromatin associated with the nucleolus. that makes it possible to distinguish them from chick cells after feulgen-rossenbeck staining and by electron microscopy. by grafting bursal rud ... | 1975 | 1101262 |
| ontogeny of lactate dehydrogenase isozymes in chicken-quail hybrid embryos. | the ontogeny of lactate dehydrogenase (ldh) isozymes was examined in avian hybrids and compared with the isozyme patterns of the parental species. hybrids were obtained by crossing female japanese quali (coturnix coturnix japonica) with male domestic chickens (gallus gallus domesticus). by use of starch gel electrophoresis and an enzyme-specific stain, traces of embryonic paternally derived ldh were detected in unincubated hybrid eggs. it was concluded that the embryonic genes coding for the b s ... | 1975 | 1137566 |

| development of a new vaccine against turkey meningo-encephalitis using a virus passaged through the japanese quail (coturnix coturnix japonica). | turkey meningo-encephalitis virus could be adapted to the japanese quail by intra-cerebral inoculation. after 4 passages the virus was found to be less pathogenic for the turkey. further attenuation could be achieved by growing the virus in japanese quail kidney cell cultures for 11 passages. this attenuated virus was used for the preparation of a live vaccine against turkey meningo-encephalitis. the safety and efficacy of the vaccine was shown in laboratory and field experiments. | 1975 | 18777300 |
| the chronic toxicity of methiocarb to grackles, doves, and quail and reproductive effect in quail. | methiocarb (4-methylthio-3, 5-xylyl n-methyl carbamate, mesurol, bay (3744), a bird repellent, was fed in concentrations of 100 to 1,000 ppm to common grackles (quiscalus quiscula), mourning doves (zenaida macroura), and breeding pairs of coturnix quail (coturnix coturnix) to investigate the possibility of cumulative intoxication. although aversion to treated diets was readily apparent in most of the tests, the 28- to 30-day median lethal concentration (lc50) was determined to be greater than 10 ... | 1975 | 1203576 |

| [analysis of pattern preferences in japanese quail (coturnix coturnix japonica; galli, aves) with reference to inborn and acquired components]. | japanese quails were examined as to whether inborn or environmental factors were decisive for visual white-black pattern preference. by different breeding conditions (patterning of the environment, sight contact with other quails, knowledge of the food form) it was found out that bright surfaces were preferred to dark ones; young quails preferred patterns resembling the plumage of their own species, whereas older ones favoured those corresponding to their favourite food. furthermore, activities ... | 1976 | 1014936 |
| [demonstration in japanese quails of genetic differences in survival from hypoxia]. | 164 quails (coturnix coturnix japonica; 94 males and 40 females), 27-55 days old and belonging to 9 families, each family being issued from a different couple of parents, were submitted to an acute nitrogen hypoxia which resulted in an overall mortality of 43.29%. the fact that a high statistically significant (p less than 0,001) heterogeneity was pointed out in these different families supports the existence of a genetic component of resistance towards hypoxia. | 1976 | 825239 |
| effect of dde, ddt and calcium on the performance of adult japanese quail (coturnix coturnix japonica). | two experiments were conducted to determine the effects of dde, ddt and calcium on performance of quail. the quail received diets containing 0 or 100 p.p.m. of dde for eight 28-day periods in exp. 1 and 0, 100 or 300 p.p.m. of dde or 100 p.p.m of ddt for six periods in exp. 2. diets containing either 0.5 or 3% calcium were used with each pesticide level. no differences in egg shell thickness, cracked eggs, egg production, feed consumption, egg weights, female body weights, fertility or hatchabil ... | 1976 | 1019080 |
| calcium balance in the quail (coturnix coturnix japonica). 1, influence of sex and diethylstilbestrol. | young adult male and laying female quail, fed with a diet containing 2.64% ca and 0.70% p, were used to study nutritive utilization, corporal calcium retention and endogenous excretion, calcemia, laying and properties of the egg (including the shell structure), mineralization of the femur bone, as well as the influence of diethylstilbestrol upon these parameters. the coefficient of nutritive utilization (c.n.u.) in the female was high and logically superior to that of the male, while the corpora ... | 1976 | 1019078 |

| effects of sevin on the reproductive biology of the coturnix. | adult coturnix quail (coturnix coturnix japonica) were subjected to three levels of carbaryl pesticide treatment (sevin-20 p.p.m., 40 p.p.m., and 400 p.p.m) and monitored to observe any modifications in either their reproductive biology or behavior. there was an increase in the amount of pesticide excreted with increasing treatment levels during the first 48 hours following intubation, after which pesticide levels in the fecal material for all groups approached zero. addditionally, significant a ... | 1976 | 828254 |
| [parathion axial teratogenesis after giving several compounds with known anti-teratogenic or antitoxic properties in vertebrate adults or embryos after exposure to organic phosphates. study in the quail embryo (coturnix coturnix japonica)]. | axial abnormalities, highly specific of parathion, are prevented by pyridine aldoximes p2s, 2-pam and tmb4. atropine, well known as an antimuscarinic agent is ineffective and so it is for tryptophan and dmso, compounds having protective effect on some morphogenetic disturbances induced by organic phosphates. these results point out the specificity of pyridine aldoximes as alleviating agents on the characteristic axial deformities induced by parathion. | 1976 | 826344 |
| [epistatic disequilibrium in an experimental population of japanese quail (coturnix coturnix japonica)]. | in an experimental population of the japanese quail coturnix coturnix japonica, two polymorphic ovoglobulin loci, two polymorphic esterase loci, and pgd versus g-6-pd loci are in epistatic disequilibrium. epistatic interactions occur between structurally and physiologically very closely related proteins and enzymes. | 1976 | 135610 |
| ultrastructure of the organum vasculosum of the lamina terminalis of the japanese quail, coturnix coturnix japonica. | the structure of the organum vasculosum of the lamina terminalis (ovlt) of the japanese quail has been studied by light and electron microscopy. the ovlt has a palisade arrangement. it forms a part of the terminal plate extending from the optic chiasma to the anterior commissure and is characterized by a special vascular arrangement. the organ consists of ependymal, internal and external zones. the ventricular surface of the organ is covered by non-ciliated ependymal cells characterized by the p ... | 1976 | 991207 |
| comparison of predicted with actual body weight selection gains of coturnix coturnix japonica. | results of nine generations of individual selection for six-week large and small body weight of japanese quail (coturnix coturnix japonica) are reported. the objectives of this study were three-fold: 1) to estimate genetic variation of body weight of coturnix quail at six weeks; 2) to predict selection gains when selecting on an individual basis for large and small body weight; and 3) to conduct a selection program for large and small females and males, respectively, with greater response in the ... | 1976 | 24414762 |
