| inbreeding components of body weight and growth rate in japanese quail. | 1. the parental inbreeding component of body weight and daily gain was partitioned into paternal and maternal inbreeding components and the latter were found to be the mor important. 2. the contribution of the maternal inbreeding to the depression of characters was more pronounced on 1-d-old chicks, but declined as the chicks grew. 3. the body weight taken near sexual maturity showed a low and non-significant decline. 4. in spite of differences in the body weight of the two populations of japane ... | 1976 | 1260477 |

| temporal analysis of cellular cytotoxicity and humoral factors during progession and regression of rous sarcomas in japanese quails. | temporal appearance of cellular cytotoxicity and humoral activities including blocking and arming activities during the entire course of rous sarcoma development in japanese quails was examined by microcytotoxicity assay with comparison of animals bearing regressing tumors induced by a moderate dose of virus (regressors) and animals bearing growing tumors induced by a large dose of virus (progressors). cellular cytotoxicity of the spleen cells in regressors was detected in a biphasic pattern; th ... | 1976 | 183034 |
| genetic variation of pancreatic esterase isozyme in japanese quail. | a genetic variation was found in pancreatic esterases of japanese quail which appeared to be arylesterase. it was found on the cathode side in the agar gel electrophoresis. three phenotypes, a,b and ab, were observed. these phenotypes were shown to be controlled by one autosomal locus, designated as es-4, with co-dominant alleles es-4a and es-4b. es-4 esterase isozymes were detected in all the individuals from about 4 days of age, but the activity was very weak. however, it gradually increased t ... | 1976 | 999053 |
| the effect of dietary selenium level on lead toxicity in the japanese quail. | previous studies (parizek et al., 1969) have shown significant interactions between selenium and certain heavy metals, particularly mercury and cadmium. since these elements have an affinity for sulfhydryl groups, it was proposed that a similar interaction might exist with lead. in an initial experiment, adult quail hens were given diets supplemented with 0 and 1 p.p.m. selenium and 0, 500 and 1000 p.p.m. lead in a 2 x 3 factorial arrangement. after 32 days of feeding, body weight, liver weight ... | 1976 | 934997 |

| changes in metabolite concentration in the plasma, liver and muscle of feed restricted japanese quail exposed to cold. | quail fed ad libitum and 50% ad libitum were cold exposed for several weeks, during time control quail remained at 21 degrees c. the concentration of plasma glucose, ffa, and uric acid, tissue glycogen and carcass fat content was measured at the end of the cold exposure period. quail fed ad libitum showed no significant change in the levels of plasma and tissue metabolites, or the carcass fat content, following cold exposure. the feed consumption by the cold exposed quail increased, and the mean ... | 1975 | 54130 |
| relationship of embryonic development to egg weight, hatch weight, and growth in japanese quail. | relationships between egg, embryo, hatch, two-week and four-week body weights of three quail lines differing in growth rate were investigated. two of the quail lines had previously undergone 29 generations of selection for increased four-week body weight, and the third line was a nonselected control. selected lines produced heavier eggs, larger 10 to 11 day embryos, and larger chicks. percent embryo weights were similar for all three lines indicating that correction for egg size eliminated diffe ... | 1975 | 1161716 |

| effects of hormonal pretreatment of cardiac necrosis in the japanese quail. | male japanese quail castrated and treated with beta-estradiol-3-benzoate for 3 wk were more resistant than sham-operated males to the necrogenic effects of massive doses of isoproterenol. the estrogen-treated castrate also weighed significantly more and had significantly lower hematocrit ratios than either the sham-operated male or the intact male. these results indicate that there is a definite sex-related protective effect this type of cardiac necrosis which cannot be explained on the basis of ... | 1975 | 1153402 |

| genetical control of phosphoglucose isomerase isozymes in the japanese quail erythrocytes. | three phenotypes of phosphoglucose isomerase (pgi) from the japanese quail erythrocytes were observed by horizontal starch gel electrophoresis. population and family data from one laboratory population of quail was consistent with the theory that pgi polymorphism was controlled by two codominant, autosomal alleles designated pgif and pgis with gene frequency values 0.25 and 0.75, respectively. the study supported the earlier view that the japanese quail is highly polymorphic with regard to bioch ... | 1975 | 1200415 |
| new animal model for atherosclerosis research. | japanese quail were investigated for their utility as a model for the discovery and evaluation of anti-atherosclerosis compounds. although they possessed suitable characteristics for a screening animal, their development of atherosclerosis was too variable to make them a practical model. a search was conducted to find a means to make quail uniformly atherosclerotic. to this end a line of quail susceptible to experimental atherosclerosis (sea) were selectively bred. thus, the sea japanese quail i ... | 1975 | 1199872 |
