After slaughter, ovaries and blood were collected. Ovaries were used for histology, fatty acid profiling, and gene expression analysis, while plasma was used to measure progesterone (P4), testosterone (T), estradiol-17\u03b2 (E2), follicle-stimulating hormone (FSH), and anti-M\u00fcllerian hormone (AMH) concentrations. Both RO and SO reduced the number of primary follicles (p = 0.04), whereas RO increased the number of antral follicles (p = 0.04) compared with the control. In both supplemented groups, FSH (p = 0.04 and p = 0.035) and AMH (p = 0.04) concentrations were higher. RO increased P4 and E2 (p = 0.03 and p = 0.013) concentrations, while SO only increased P4 (p = 0.02) levels. SO altered the ovarian fatty acid profile, increasing selected monounsaturated fatty acids and reducing polyunsaturated fatty acids, likely by increasing the expression of the converting enzyme, stearoyl-CoA desaturase 5 (p = 0.038). Overall, both oils influenced folliculogenesis through hormonal changes, and SO modified ovarian fatty acid composition, which may affect ovarian function in juvenile rabbits.<\/jats:p>","DOI":"10.3390\/ani16101528","type":"journal-article","created":{"date-parts":[[2026,5,18]],"date-time":"2026-05-18T08:56:27Z","timestamp":1779094587000},"page":"1528","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Dietary Supplementation with Raspberry or Strawberry Seed Oil Impacts Folliculogenesis, Hormonal Parameters and the Fatty Acid Profile in the Juvenile Rabbit Ovary"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2972-1755","authenticated-orcid":false,"given":"Ma\u0142gorzata","family":"Grzesiak","sequence":"first","affiliation":[{"name":"Department of Endocrinology, Institute of Zoology and Biomedical Research, Faculty of Biology, Jagiellonian University, Gronostajowa 9, 30-387 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katarzyna","family":"Michta","sequence":"additional","affiliation":[{"name":"Department of Endocrinology, Institute of Zoology and Biomedical Research, Faculty of Biology, Jagiellonian University, Gronostajowa 9, 30-387 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kalina","family":"Gali\u0144ska","sequence":"additional","affiliation":[{"name":"Department of Endocrinology, Institute of Zoology and Biomedical Research, Faculty of Biology, Jagiellonian University, Gronostajowa 9, 30-387 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6018-6888","authenticated-orcid":false,"given":"Micha\u0142","family":"Kmiecik","sequence":"additional","affiliation":[{"name":"Department of Genetics, Animal Breeding and Ethology, University of Agriculture in Krakow, Al.
