A total of 72 (8 replicates, 3 hens\/subgroup) laying hens (Nick Brown, 30\u202fweeks) were divided into three groups (FRP-0, FRP-1, FRP-2). During the 9-week trial, FRP-0 (control) was fed with a basal diet (16.88% crude protein, 2,725\u202fkcal\/kg metabolizable energy). FRP-1 and FRP-2 groups, however, were fed a diet supplemented with 1\u202fg\/kg and 2\u202fg\/kg\u202fFRP, respectively. The results showed that laying performance, serum hormone (estradiol, progesterone) levels, and some internal organ weights were not affected by FRP supplementation. In comparison to the control group, higher yolk height and yolk index were found in the FRP-added groups. The albumen pH was found to have decreased in FRP-2 group. DPPH radical scavenging activity increased in egg yolk. TBARs value decreased in FRP-1 and FRP-2 groups. Serum triglyceride and cholesterol levels decreased in group FRP-2. Moreover, a higher uterus length was found in the FRP-supplemented group. Given the results achieved, it was determined that FRP does not have a significant estrogenic effect. However, FRP can be utilized to prevent lipid oxidation and for its hypocholesterolemic effect.<\/jats:p>","DOI":"10.3389\/fvets.2024.1525101","type":"journal-article","created":{"date-parts":[[2025,1,22]],"date-time":"2025-01-22T07:18:17Z","timestamp":1737530297000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Ferula (Ferula elaeochytris) as a phytoestrogen: Use of Ferula in laying hens"],"prefix":"10.3389","volume":"11","author":[{"given":"Arda Onur","family":"\u00d6zk\u00f6k","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G\u00f6zde","family":"K\u0131l\u0131n\u00e7","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2025,1,22]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"405","DOI":"10.15547\/tjs.2020.04.016","article-title":"Non-hormonal feed additives as an alternative in animal reproduction","volume":"18","author":"Mihaylova","year":"2020","journal-title":"Trakia J Sci"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"648","DOI":"10.1016\/j.neubiorev.2021.12.007","article-title":"Estrogens and phytoestrogens in body functions","volume":"132","author":"Ceccarelli","year":"2022","journal-title":"Neurosci Biobehav Rev"},{"key":"ref3","first-page":"45","article-title":"Female reproductive health-regulating hormones and phytosteroids as alternative modulator: A review","volume":"2","author":"Sarma","year":"2023","journal-title":"Annal Multidiscip Res Innov Technol"},{"key":"ref4","doi-asserted-by":"publisher","first-page":"98","DOI":"10.1016\/j.mce.2016.12.013","article-title":"Phytosteroids beyond estrogens: regulators of reproductive and endocrine function in natural products","volume":"442","author":"Dean","year":"2017","journal-title":"Mol Cel Endocrinol"},{"key":"ref5","doi-asserted-by":"publisher","first-page":"143","DOI":"10.5653\/cerm.2023.05995","article-title":"Review of potential spermatogenic and aphrodisiac effects of the Ferula genus","volume":"50","author":"Bagheri","year":"2023","journal-title":"Clin Exp Reprod Med"},{"key":"ref6","doi-asserted-by":"publisher","first-page":"437","DOI":"10.1055\/s-0043-109100","article-title":"Phytochemistry and pharmacology of Ferula hermonis Boiss.\u2013a review","volume":"67","author":"Sattar","year":"2017","journal-title":"Drug Res"},{"key":"ref7","doi-asserted-by":"publisher","first-page":"283","DOI":"10.1016\/j.bbr.2008.12.009","article-title":"The phytoestrogen ferutinin affects female sexual behavior modulating ER\u03b1 expression in the hypothalamus","volume":"199","author":"Zanoli","year":"2009","journal-title":"Behav Brain Res"},{"key":"ref8","doi-asserted-by":"publisher","first-page":"1905","DOI":"10.3390\/plants11151905","article-title":"Ferula communis L.
