This study aimed to investigate the effects of milk yield, blood \u03b2\u2010hydroxybutyrate (BHBA) concentrations, and parity on oxidative stress (diacron\u2010reactive oxygen metabolites [d\u2010ROMs]) or antioxidant activity (biological antioxidant potential [BAP]) in the uterine flush fluid of lactating Holstein Friesian dairy cows. Uterine flush fluid samples were collected at 4, 5, 6, and 8\u2009weeks postpartum (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u200943), and d\u2010ROMs and BAP were measured. d\u2010ROMs, BAP, and oxidative stress index (OSI) were investigated in relation to the correlation between milk yield and BHBA concentrations. Cows were classified into primiparous cow groups (P group,\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u200911), biparous cow group (B group,\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u20095), and the third or more calving groups (M group,\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u200927); d\u2010ROMs, BAP, and OSI changes were evaluated across the groups. No significant correlations were noted between milk yield, blood BHBA concentrations, and d\u2010ROMs, BAP, or OSI. The M group exhibited higher d\u2010ROMs and OSI than the P group at 5\u2009weeks, and the M group had a higher OSI than the B group at 6\u2009weeks. Therefore, parity may influence uterine OS and antioxidant activity.\n                  <\/jats:p>","DOI":"10.1111\/asj.70156","type":"journal-article","created":{"date-parts":[[2026,1,27]],"date-time":"2026-01-27T07:12:53Z","timestamp":1769497973000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Effects of Milk Yield, Blood \u03b2\u2010Hydroxybutyrate Concentrations, and Parity on Oxidative Stress and Antioxidants in Uterine Flush Fluid During the Early Postpartum Period in Lactating Holstein Friesian Dairy Cows"],"prefix":"10.1111","volume":"97","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-8915-7499","authenticated-orcid":false,"given":"Yujiro","family":"Hagita","sequence":"first","affiliation":[{"name":"Fuji Animal Farm Nippon Veterinary and Life Science University  Minamitsuru\u2010gun Yamanashi Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryotaro","family":"Miura","sequence":"additional","affiliation":[{"name":"School of Veterinary Medicine Rakuno Gakuen University  Ebetsu\u2010shi Hokkaido Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Koumei","family":"Shirasuna","sequence":"additional","affiliation":[{"name":"Department of Animal Science Tokyo University of Agriculture  Atsugi\u2010shi Kanagawa Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tsuyoshi","family":"Tajima","sequence":"additional","affiliation":[{"name":"School of Veterinary Medicine Nippon Veterinary and Life Science University  Musashino\u2010shi Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-9815-5715","authenticated-orcid":false,"given":"Kazuhiro","family":"Bandai","sequence":"additional","affiliation":[{"name":"School of Veterinary Medicine Nippon Veterinary and Life Science University  Musashino\u2010shi Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tadaharu","family":"Ajito","sequence":"additional","affiliation":[{"name":"School of Veterinary Medicine Nippon Veterinary and Life Science University  Musashino\u2010shi Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hirotaka","family":"Matsumoto","sequence":"additional","affiliation":[{"name":"School of Veterinary Medicine Nippon Veterinary and Life Science University  Musashino\u2010shi Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,1,26]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1017\/S1751731113000396"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1163\/156856700X00769"},{"key":"e_1_2_8_4_1","doi-asserted-by":"crossref","unstructured":"Aydilek N.
