Laying quails were assigned to three dietary groups. The control group (Group C) received the basal diet (laying feed containing 9000 IU vitamin A\/kg). In the treated groups (Groups BC1 and BC2) the basal diet was supplemented with 102and 103mg\/kg (-carotene (BC), respectively. At the end of the two-week feeding period, 10 birds from each group were euthanised. Blood samples were analysed for retinol, retinyl palmitate and (-carotene concentrations. Granulosa cells were isolated from ovarian follicles (F1and F2), and PMSG-inducedin vitroprogesterone (P4) secretion was measured. Similar retinol concentrations were found in both (-carotene supplemented groups, indicating saturation of the retinol-transporting system. (-carotene supplementation was accompanied by hypercarotenaemia, but did not increase the retinyl palmitate levels in the blood. PMSG-induced P4production of the granulosa cells decreased significantly in Groups BC1 and BC2 in a dose-dependent manner.<\/jats:p>","DOI":"10.1556\/avet.48.2000.1.9","type":"journal-article","created":{"date-parts":[[2005,10,21]],"date-time":"2005-10-21T19:28:11Z","timestamp":1129922891000},"page":"81-87","update-policy":"http:\/\/dx.doi.org\/10.1556\/policypage.crossmark.crossref.1","source":"Crossref","is-referenced-by-count":1,"title":["Effect of large dietary doses of \u00df-carotene on plasma retinoid AND \u00df-carotene levels and ON progesterone production in the granulosa cells of Japanese quail"],"prefix":"10.1556","volume":"48","author":[{"given":"Gabriella","family":"\u00c1gota","sequence":"first","affiliation":[{"name":"1 Goose Breeding Research Station, Department of Animal Physiology and Health, University of Agricultural Sciences Please ask the editor of the journal."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L.","family":"B\u00e1rdos","sequence":"additional","affiliation":[{"name":"2 Department of Animal Physiology and Hygiene, Faculty of Animal Science, University of Kaposv\u00e1r Please ask the editor of the journal."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Pusztai","sequence":"additional","affiliation":[{"name":"3 Department of Animal Physiology and Health, G\u00f6d\u00f6ll\u0151 Agricultural University Please ask the editor of the journal."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"425","reference":[{"key":"2","first-page":"319","article-title":"Rapid determination of vitamin A (retinol) and vitamin E (\u03b1-tocopherol) in human serum by isocratic adsorption HPLC","volume":"56","author":"H.
