| the prolonged exposure of japanese quail to carbaryl and its effects on growth and reproductive parameters. | carbaryl fed to japanese quail over a 14 week period resulted in decreased body weight, increased relative brain, liver and kidney weights in one or both sexes at levels of 900 ppm or higher. significant differences were not found in the f1 birds at the same levels after 6 weeks. it appears that the time of exposure is critical and that parental diet is not. there were no significant differences in egg production, hatchability or fertility although trends toward reduction of these parameters wer ... | 1977 | 403986 |
| effects of pcbs, ddt, and mercury compounds in chickens and japanese quail. | in well-controlled experiments using white leghorn chickens and japanese quail, dietary polychlorinated biphenyls (pcbs), ddt and related compounds produced no detrimental effects on eggshell quality. a drastic reduction in hatchability of chicks occurred with 10-20 ppm pcbs, but no detrimental effects on eggshell quality, egg production or hatchability were found with 0.5 and 1.0 ppm pcbs, or ddt up to 100 ppm. dietary pcbs potentiated a vitamin e-selenium deficiency in the chick, increased exu ... | 1977 | 404195 |
| [germ cell colonization of gonads in experimental quail twin embryos (coturnix coturnix japonica)]. | at the same development stage, two quail twin embryos from right and left halves of a blastoderm contain together as many germ cells as a normal embryol. these are asymmetricaly distributed between the twins as between the right and left genital ridges of control embryos. | 1977 | 410552 |
| [effects of herbicides (gramoxone and defenuron) on the development and protein levels of quail (coturix coturix japonica)]. | the herbicides gramoxone (active substance paraquat dichloride) and defenuron (active principle n-phenyl-n'-methylurea) were studied as influencing the development of the japanese quail (coturnix coturnix japonica) and the proteins in their blood serum. the aqueous solution of gramoxone (500 ppm), applied to the egg surface, reduces the hatchability percentage and delays hatching. under similar conditions, defenuron has no inhibitory effect on embryonal development. gramoxone in drinking water ( ... | 1977 | 411224 |
| [postnatal development of enzyme activities of nitrogen catabolism in the liver of japanese quail]. | in the course of postnatal development from the hatching up to the age of 84 days, the activities of xanthine dehydrogenase (xdh), glutamate dehydrogenase (gldh) and arginase were examined in the liver of japanese quail. the observation in weekly intervals showed a gradual character of xdh development whereas the conclusion of the first degree correlated to some extent with the period of achieving the sexual maturity of animals. the gldh activity increased in the course of the growth with attain ... | 1977 | 411225 |
| studies on eimeria dispersa tyzzer 1929 in turkeys. | eimeria dispersa was isolated from young, intensively housed turkeys in britain. the parasite has morphological features in common with those of the original description. at least two generations of schizonts occur before gametogony and one or two more schizont generations are concurrent with gametogony. four generations of schizonts are needed to account for the observed reproduction index of 2.08 x 10(6)/oocyst inoculated. the first oocysts were discharged by 105 h and these sporulated within ... | 1979 | 419003 |
| a rapid bioassay system for lead using young japanese quail. | a rapid bioassay of lead was established in young japanese quail. each group of 10 day-old birds received deionized water and a purified diet ad libitum for 2 wk. the diet contained 0.2 microgram lead/g. lead acetate was added to give 14.8, 34.4, 51.2, 74.4, 234, 563, or 1223 microgram total lead/g by analysis. the duodenum, kidneys, liver and tibias were assayed for lead. consumption of a diet containing either 563 or 1223 ppm lead caused a decrease (p less than or equal to 0.05) in body weight ... | 2013 | 422934 |
| the epididymal region of the japanese quail (coturnix coturnix japonica). | the epididymal region of the japanese quail was studied histologically. the organ consists of the extratesticular portion of the rete testis, the ductuli efferentes proximales and distales, the ducti conjugentes and ductus epididymidis. distinct tubuli recti link the seminiferous tubules with the rete testis. the non-ciliated cells of the ductuli efferentes proximales and distales show, between them, certain internal structural differences which were highlighted. in 40% of the birds, the ductus ... | 1979 | 433566 |
| effect of estrogen on rate of 59fe uptake by hemopoietic tissue in japanese quail. | injection of 2 mg estradiol valerate into male japanese quail caused the rate of 59fe uptake by the skeleton to drop 70% within 48 h. this phenomenon was due to an increase in the iron-binding capacity of the plasma induced by estrogen that caused a substantial decline in the availability of the label for hematopoiesis and to partial inhibition of hematopoiesis by estrogen directly. the changes in 59fe uptake induced by estrogen were accompanied by a significant drop in circulating red blood cel ... | 1979 | 434196 |
| the influence of the sex-hormone testosterone on body temperature and metabolism of the male japanese quail (coturnix coturnix japonica). | testosterone causes a significant body temperature decrease in male quails. oxygen consumption/g b. wt remains the same, however. | 1979 | 437037 |

| effects of light and of testosterone derivatives or antiandrogens on the secretory content of the subcommissural organ of the quail, coturnix coturnix japonica. | photosensitivity of the quail subcommissural organ (sco) is demonstrated. when the birds are submitted to continuous light the sco cells appear depleted in secretory material and the enzyme activities investigated are of greater intensity. such a diminished secretory content is observed in birds exposed to short daylength when they are injected with testosterone derivatives. besides, injections of antiandrogenic compounds in continuously illuminated quails abolish the decrease of the secretory m ... | 1979 | 458434 |
| acute effects of parathyroid extract on renal vitamin d hydroxylases in japanese quail. | the dose- and the time-response relationships of parathyroid hormone's modulation of in vitro 1,25-(oh)2d3 and 24,25-(oh)2d3 production in japanese quail were investigated. 4-week-old female japanese quail were injected intramuscularly with three different doses (30, 90 and 270 usp units/kg) of parathyroid extract (pth). 4, 12 and 24 h after the in vivo administration of pth, kidney homogenates were incubated with tritiated 25-(oh)d3. all three doses of pth stimulated 1,25-(oh)2d3 and inhibited ... | 1979 | 461495 |
| the effects of 1,1-di(p-chlorophenyl)-2-chloroethylene on plasma enzymes and blood constituents in the japanese quail. | glutamate oxaloacetate transminase (got), glutamate dehydrogenase (gdh), sorbitol dehydrogenase (sdh), pseudo-cholinesterase (che) and various blood constituents were measured in the plasma of japanese quail fed 1,1-di(p-chlorophenyl)-2-chloroethylene (ddmu) at low levels for periods ranging from 2 to 32 days. previous work has shown that ddmu is a potent inducer of hepatic microsomal enzymes causing marked structural changes in the liver. a rapid increase in plasma got was observed within 4 day ... | 1979 | 466732 |
| effects of accelerating stimulation on different indices of development in japanese quail embryos. | effects of continuous accelerating stimulation on the timing, duration and rate of occurrence of different indices of development in japanese quail embryos were examined. indices used were: the onset of breathing and hatching, also pipping, clicking, vocalisation, membrane penetration, yolk sac withdrawal and lung aeration. results showed that embryos stimulated by clicks began breathing about nine hours in advance of unstimulated controls and hatched about 23 hours in advance. all other indices ... | 1979 | 469484 |
| reproductive responses of quail to bunker c oil fractions. | bunker c fuel oil was extracted with petroleum ether and the concentrated extract was given to breeding japanese quail (coturnix coturnix japonica). a dose of extract equivalent to 300 mg bunker c reduced both egg production and hatchability. fractionation of the extract by absorption on florisil and elution with petroleum ether followed by chloroform yielded fractions that were tested for toxicity. all the fractions had a pronounced effect upon production; however, only the chloroform eluates w ... | 1979 | 485214 |
| characterization of paramyxo-, herpes-, and orbiviruses isolated from psittacine birds. | isolates of paramyxo-, herpes-, and orbiviruses from psittacine birds were characterized in the course of studies in cell cultures. the lbd-1 isolate, from a lovebird, was grown in chick kidney (ck) cells. it had the properties of a paramyxovirus but was found tobe serologically distinct from known avian paramyxoviruses. this virus was pathogenic for japanese quail but not for young chickens or budgerigars. rsl-1 and -2, isolated from diseased rosellas, were propagated in chicken embryo fibrobla ... | 1979 | 486000 |
| involvement of catecholaminergic nerve fibers in angiotensin ii-induced drinking in the japanese quail, coturnix coturnix japonica. | monamine distribution in a septohypothalamic area was investigated in the japanese quail using a histochemical fluorescence method. this area includes the subfornical organ (sfo) and the preoptic area (poa) which are inferred dipsogenic receptor sites for angiotensin ii (aii) in the japanese quail. nerve fibers showing yellow-green fluorescence were found between the poa and the sfo. thwy traversed from the poa to the sfo, and some fibers seemed to terminate on the neurons in the sfo. after a lo ... | 1979 | 487128 |
| effects of nutritional factors on metabolism of dietary cadmium at levels similar to those of man. | several nutrients are known to affect cadmium toxicity, but little is known about the effect of dietary nutrient levels on absorption and tissue retention of cadmium at low dietary levels, similar to those of man. feeding gradedlevels of zinc in a casein-gelatin diet to young japanese quail with 109cd (as the chloride) and 0.062 ppm added cadmium decreased the cadmium concentrations in the proventriculus-ventriculus, duodenum, jejunum-ileum, and the liver, but not in the kidney. zinc also affect ... | 1979 | 488027 |
| effect of embryonic treatment with estradiol or testosterone on sexual differentiation of the quail brain. critical period and dose-response relationships. | japanese quail eggs were injected with estradiol benzoate (eb) after 10, 11, 12, 13, or 14 days of incubation, or were injected on day 10 with one of six dosages of eb or seven dosages of testosterone propionate (tp). eb injected on day 10 of 11 demasculinized the males; as adults they were incapable of copulating in response to exogenous tp. eb injected on day 13 or 14 was without effect, and eb injected on day 12 caused slight demasculinization. the critical period for sexual differentiation o ... | 1979 | 492478 |
| effects of diazacholesterol, triparanol, and beta-sitosterol on egg cholesterol deposition in coturnix quail. | studies were undertaken to determine the effect of inhibitors of cholesterol synthesis on deposition of cholesterol in eggs of japanese quail. results indicate that this bird responds similarly to the laying hen, making it a useful screening device for these types of compounds. administration of either triparanol or 20,25 diazacholesterol resulted in a decreased cholesterol content of the yolk. concomitant with this decrease was an increase in desmosterol deposition. beta sitosterol (2%) fed eit ... | 1979 | 493220 |
| effect of testosterone and thyroxine on corticosterone and transcortine plasma levels in different bird species. | effect of testosterone and thyroxine on corticosterone and transcortine plasma levels has been investigated in photostimulated (18l--6d) peking duck, domestic pigeon, japanese quail and cock. in all these bird species corticosterone and transcortine plasma levels increased following castration, while restitution with testosterone decreased them in the castrated animals. thyroidectomy and thyroxine supplements in thyroidectomized birds failed to influence plasma corticosterone and, apart from coc ... | 1979 | 495129 |
| the toxicity of hexachloroethane in laboratory animals. | studies were conducted to assess hazards to personnel exposed to hexachloroethane (hce) in an industrial setting. acute testing in laboratory animals indicated hce was moderately toxic orally and could produce reversible eye irritation and mild skin irritation. percutaneous absorption appeared to have no practical significance. the subchronic vapor inhalation toxicity was determined in rats, guinea pigs, japanese quail and dogs in a 6-week test, monitoring pulmonary function changes, teratogenic ... | 1979 | 495459 |
