Glucocorticoid Metabolism

Maternal effects have gained attention as a method by which mothers may alter the physiological condition and phenotype of their offspring based upon current environmental conditions. The physiological and phenotypic outcomes of glucocorticoid-mediated maternal effects have been extensively studied in a variety of vertebrates; however, the underlying mechanism is currently unclear. Here, we injected tritiated corticosterone into the yolks of freshly laid Japanese quail eggs ( Coturnix japonica ) and traced its movement and metabolism through the in ovo development period. We found that corticosterone was extensively conjugated throughout the egg by the end of development, and while minimal corticosterone was detected within the embryo during development, accumulation of a conjugated metabolite in the embryo started to occur on day 6 of development. Because no movement and metabolism of corticosterone occurred in infertile eggs, our findings suggest that embryos are not passive recipients of maternal steroids, but instead appear to possess extensive metabolic capabilities, which may modulate their exposure to maternal steroids.

Oestrogen is needed for normal oviductal development in female birds, but excessive early exposure to oestrogen can cause oviductal abnormalities and impair egg-laying ability. In this study, the anatomical and histological effects of in ovo exposure to the synthetic oestrogen ethynyloestradiol on the oviducts of immature and adult female Japanese quail, Coturnix japonica, were investigated. A series of abnormalities was observed after injection of ethynyloestradiol (2 or 20 ng g(-1) egg) into the yolk on day 3 of incubation. Ethynyloestradiol induced precocious differentiation of the luminal epithelium and tubular glands in immature chicks. Right-side oviduct retention occurred at all the ages studied, whereas certain other effects were not evident until sexual maturity. The left oviduct was reduced in size and tubular gland density in the uterus (shell gland) was reduced in sexually mature birds that had been treated with ethynyloestradiol. The utero-vaginal junction was longer than in control birds and had a higher tubular gland density. The epithelial cells in the magnum were taller in birds treated with ethynyloestradiol. Embryonic exposure to the environmental contaminant ethynyloestradiol may cause persisting structural malformations in oviducts of quails, which can impair fertility. As oviductal malformations are indicative of embryonic exposure to exogenous oestrogen, they are potentially useful as biomarkers of xenooestrogen exposure in wild bird populations.

Quail is one of poultry commodities that compliance the needed of animal protein like egg and meat. Good quality was breed from quail parent that has good physiological condition. This research aimed to quantified cholesterol of quail meat from F1 from quail parent that treatment using turmeric powder supplement on itsfed in order to obtained best quail chick with good physiological condition. This research use Completely Randomized Design (CRD) experimental method. Animal on this research was 15 Japanese quail (Coturnix coturnix japonica L.) hens that gave 3 treatments with 5 repetitions. K0 was F1 of quail parent without turmeric powder supplementation, K1 was F1 of quail parent with 54 mg/quail/day turmeric powder supplementation before its sex period, K2 was F1 of quail parent with 108 mg/quail/day turmeric powder supplementation before its sex period. The F1 quail was fed using standard quail feed. Data was obtained from daily fed consumption average, daily water consumption, and quail meat cholesterol rate on 60 day old chicken. Data was analyses using Analysis of Variance (ANOVA). This research result showed that daily fed consumption, daily water consumption and meat cholesterol rate of F1 that treatment using turmeric powder supplementation wasn’t show significant difference, so conclusion of this research is physiological condition of F1 was normal. Key words: Quail Meat Cholesterol, F1 of Japanese quail (Coturnix coturnix japonica), Turmeric powder
