Muscovy duck (C. moschata), an important indigenous genetic resource in Indonesia, requires effective semen preservation methods to support breeding programs.\n\nAim: \nThis study investigated the effects of different glutathione (GSH) and vitamin C concentrations on the quality and longevity of Muscovy duck semen during cold storage. The novelty of this research lies in its focus on Muscovy ducks, the evaluation of multiple antioxidant concentrations, and detailed observation intervals to optimize semen preservation.\n\nMethods: \nFresh semen was collected from adult Muscovy ducks and diluted with Ringer\u2019s lactate extender supplemented with GSH (0.1, 0.2, 0.3, and 0.4 mM) or vitamin C (0.568, 1.136, 1.704, and 2.272 mM). The diluted semen was stored at 5 \u00b0C and evaluated every 12 h for motility, viability, abnormalities, and membrane plasma integrity. Longevity was defined as the duration during which motility and viability remained &gt;50%.\n\nResults: \nBoth antioxidants significantly influenced all semen quality parameters during storage (P &lt; 0.01). Treatment with 0.1 mM GSH and 0.568 mM vitamin C consistently preserved higher motility, viability, and membrane integrity while minimizing abnormalities. These concentrations also yielded the highest semen longevity.\n\nConclusion: \nAppropriate GSH and vitamin C concentrations effectively maintained the quality and longevity of Muscovy duck semen during cold storage. These antioxidants show potential for improving AI outcomes in poultry.<\/jats:p>","DOI":"10.5455\/ovj.2026.v16.i2.25","type":"journal-article","created":{"date-parts":[[2026,2,28]],"date-time":"2026-02-28T12:03:12Z","timestamp":1772280192000},"page":"1048","source":"Crossref","is-referenced-by-count":0,"title":["&lt;b&gt;Optimization of the best extender for liquid semen of Muscovy duck (&lt;i&gt;Cairina moschata&lt;\/i&gt;) with the addition of different concentrations of vitamin C and glutathione&lt;\/b&gt;"],"prefix":"10.5455","volume":"16","author":[{"given":"Betri","family":"Agustin","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tinda","family":"Afriani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tertia","family":"Nova","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ananda","family":"Ananda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3407","container-title":["Open Veterinary Journal"],"original-title":[],"link":[{"URL":"https:\/\/www.bibliomed.org\/fulltextpdf.php?mno=276128","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,8]],"date-time":"2026-10-08T18:19:37Z","timestamp":1791483577000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.openveterinaryjournal.com\/?mno=276128"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2026]]}},"URL":"https:\/\/doi.org\/10.5455\/ovj.2026.v16.i2.25","relation":{},"ISSN":["2226-4485"],"issn-type":[{"value":"2226-4485","type":"print"}],"subject":[],"published":{"date-parts":[[2026]]}}}
